Best online casino sites 2026

The best online casino sites internationally largely depend on where you, the browser, are located with many countries having their own regulated gambling industries. For instance, real money casinos in the USA are regulated on a state-by-state basis, meaning only seven have legal gambling sites available to them.

The top online casinos for countries in Europe can also be vastly different, depending on your location, with some regulating their own industry, while others either ignore it or allow residents to play with Malta-based brands, which pay tax in the European Economic Union.

The best online casinos often have upwards of 2000 casino games from a variety of iGaming developers, with the majority of these online slots, which are exceptionally popular in many places. Online casino initiatives like Crash Games and live dealer products, including classics like blackjack and roulette, and gameshows have made the industry competitive with land-based casinos.

These days many of the best casinos online will also feature sports betting, with this including major brands in places like the United Kingdom and the USA, and essentially where the laws allow it. Places like Australia, have outright banned online casinos, so you will not find casino games at Australian sports betting sites.

Probably the biggest disruptor of online casinos in recent years has been the emergence of crypto-based gambling sites, which include major brands like the Australian-based Stake.com, which via celebrity endorsements and smart marketing has take a significant chunk of the market. Online casino regulators have largely been caught napping by crypto platforms, but have slowly began to endorse these payments themselves, with Malta Gaming Authority, United Kingdom Gambling Commission and South Africa’s National gambling Board all softening their stances in recent times.

While crypto casinos have emerged, cash does remain king, and most of the top online casinos purely accept regular currencies. The most popular payment options at online casinos include credit and debit cards, web wallets, payment processors, and even mobile payment solutions.

Top 10 online casinos in the world

Often the team at the World Gambling List gets asked about the best online casinos in the world. This is obviously a matter of personal opinion, but there are some clear standouts in the gambling industry.

Things we took into consideration when ranking our best online casinos list include the markets they serve — if they don’t serve multiple markets we won’t include them. They also need strong reputations in the industry and great customer service — those two are a must.

We are constantly making changes to our ratings and this list will change from time to time, but our best online casinos in the world in 2026 include:

Leo Vegas online casino

#1 LeoVegas.com

Outstanding mobile casino

LeoVegas takes top spot in our list of the best online casinos for 2026, thanks largely to its reputation, established history and huge selection of casino games. We particularly rate its payment options and mobile casino experience, while LeoVegas withdrawals typically arrive within one to three business days once approved. Bonus offers vary depending on where you play, while instant deposit methods and exclusive games add to the overall package. LeoVegas is licensed in several regulated markets, including Great Britain by the UK Gambling Commission and internationally through the Malta Gaming Authority.

The downside is that LeoVegas’ payment options and availability can be more restrictive in parts of Asia and Africa, where players may find other casinos on our list offer a better choice of locally supported banking methods and currencies.

#2 1xCasino

New online casino

1xCasino is the new online casino from the 1xBet creators, with this URL focussing exclusively on real money casino gaming and its offshoot.

1xCasino is licensed in Curacao, and accepts many different countries, including catering to various currencies and adapting their bonuses and promotions for the user.

1xCasino has over 100 different software providers, live dealer, bingo, virtual games and more. If you are looking for a modern online casino, 1xCasino could be a solid choice and has everything you should demand.

A criticism? 1xCasino does not operate in as many regulated gambling markets as other online casinos, although this tempered by serving many grey markets.

Betway Casino

#3 Betway.com

Huge global presence

Betway is one of the most established names on our list, having built its reputation through a huge sports betting offering before expanding its online casino into a major part of the brand. Mobile users are well catered for with Betway apps available in supported markets, while its long history of sponsorships across football and other major sports has helped make it one of the most recognisable gambling brands internationally.

On the casino side, Betway offers a large selection of slots, live casino and table games, including titles from major providers such as Playtech. Regular promotions are another strong point, with offers such as the Mega Wheel joined by slots tournaments and other recurring casino rewards. Betway also operates localised sites in a number of regulated markets, although the games, bonuses and payment methods available can differ considerably depending on where you play.

William Hill Casino

#4 WilliamHill.com

Outstanding mobile casino

William Hill is one of the most well-known gambling brands on the planet, with over 80 years having passed since William Hill began taking bets.

Available in various jurisdictions, including the United Kingdom, some states in the USA and varioyus others, William Hill has huge depth in payment options, great bonus offers and outstanding mobile apps.

William Hill is not as dominant as it once was, but their close partnership with Playtech, which sees them house all their great slots, keeps them in contention as a gambling website we play at.

Mr Green Casino

#5 MrGreen.com

Classy casino-sportsbook

Mr Green Casino has continued to thrive as a real money casino destination, with their depth in games, cool theme and strong reputation keeping them at the cutting-edge.

Mr Green’s tendency to regularly run promotions and bonus offers, surrounding everything from current events to the latest casino games is a major reason we are fans.

The fact they cater to various audiences and have both a Malta Gaming Authority and Swedish license make them an attractive proposition.

The Downside of Mr Green? We were disappointed they left a key market, the UK, in October of 2024.

Temple Nile Casino

#6 TempleNile.com

New kids on the block, but top-notch service

TempleNile.com is licensed to operate in Malta, the United Kingdom and Sweden, although they are really willing to accept customers from anywhere there has not been a ban on online gambling, which encompasses grey markets such as New Zealand and Canada. Temple Nile Casino has a great selection of casino games from leading providers like Apricot, but what sets it apart is the fact it has games from upwards of 20 smaller boutique iGaming providers. Temple Nile Casino also has a great VIP rewards program, which can help you get cash and bonuses back, simply for just playing at the casino. If you want to find out more about this casino, read our Temple Nile Casino review.

Royal Vegas Casino

#7 Royal Vegas

Oldest online casino on the web

Royal Vegas Casino has been around upwards of 20 years now, with this ex-Microgaming gambling site one of the most respected on the web. While its management company has changed hands several times (it used to be run by Fortune Lounge), it is now managed by the very capable Buffalo Partners. Royal Vegas has now branched out and features games from various iGaming developers. Boasting an instant-play interface (which can be used on platforms like Mac). RV stocks all of Apricot’s slots, video poker,= and casual games. And of course their live suite of games, taken from Evolution, and several others, is also a top-notch experience. Royal Vegas is also accessible via their casino apps in some markets.

Jackpot Village

#8 Jackpot Village

New but well run online casino

Launching in the first half of 2019, Jackpot Village has quickly established itself in the iGaming world. Boasting games from a huge selection of online casino software companies, including Apricot Gaming, iSoftBet and live specialists Evolution Gaming, Jackpot Village is licensed to operate by the Malta Gaming Authority, while it also offers real money games to the UK via third party agreement. These two licences mean the casino can be trusted and is a good option for players based in European countries, Canada and New Zealand, among many others. Jackpot Village Casino has some nice promos running on a weekly basis and in their short history have continually added new games, keeping them fresh.

#9 Jackpot City

A gambling institution

Jackpot City online casino has been around for longer than we care to remember. Formerly, powered solely by Microgaming, Jackpot City has a great selection of online slots and table games from a variety of developers. This includes a great selection of live games, powered by Pragmatic Play Live, Ezugi and Evolution, with both high- and low-limit tables available. Run by the same folk as Royal Vegas, Jackpot City is a great option for players in Canada, New Zealand and much of Europe. With these target markets in mind the online casino has then added every conceivable payment method you could want. Jackpot City Casino remains one of the top online casinos in the world.

#10 Betsson Casino

European giants

A well-known online casino brand, Betsson Casino has a huge footprint in Europe and has a strong reputation right across the globe. Betsson Casino is powered by several of the industry leading software developers, including Microgaming and Net Entertainment. The online casino also features a strong live casino, with the table limits among the most diverse in the world. If you are looking for a safe online casino, Betsson is probably a good choice, particularly if you are depositing in the EUR, because they have some great promotions surrounding this currency. Betsson Casino review.


Online Casinos – The global view of gambling sites

Online casinos are worth billions of dollars to the global economy and while precise figures can be difficult to confirm due to varying reporting standards and privacy policies across jurisdictions, the overall scale is clear.

In recent years, regulated online casino markets have continued to grow, with global online gambling revenues estimated to exceed US$100 billion annually, driven by expansion in North America, Europe and emerging markets.

In the United Kingdom alone, billions of pounds are wagered each year across online casinos and betting sites, with figures reported by the UK Gambling Commission reflecting activity from licensed operators. Similar growth has been seen in regulated markets across Europe, North America and parts of Latin America.

Many governments still prohibit locally licensed online casinos, yet face ongoing challenges in preventing residents from accessing offshore sites.

Countries including the UK, Canada and the United States remain among the most valuable online gambling markets, while regulated jurisdictions across Europe continue to attract major operators. Regulation remains one of the key factors shaping how gambling companies enter, compete and grow within these regions.

Australian online casinos

Australia

Australia does not permit locally licensed real-money online casinos, and WGL does not advertise offshore casino sites to Australian players. Under the Interactive Gambling Act, operators are prohibited from offering or advertising online casino games to people in Australia, with the ACMA actively blocking illegal gambling websites. Australians can legally use licensed online sports betting sites and wagering services, while land-based casinos and lotteries remain regulated separately.

European online casinos

Europe

Europe is home to many of the world’s largest regulated online casino markets, although gambling laws and licensing requirements vary significantly by country. Major regulated markets include the UK, Italy, Spain, Sweden, Denmark, the Netherlands, Germany and Belgium, while Malta remains an important licensing hub for operators serving permitted European markets. Advertising, bonuses and player-protection rules also differ considerably between countries. See our European online casino guides for local regulations and recommendations.

USA online casinos

USA

Online casino gambling in the USA is regulated state by state, with eight states now having legalised real-money iGaming. Established markets include New Jersey, Pennsylvania, Michigan, Connecticut, West Virginia, Delaware and Rhode Island, while Maine legalised online casinos in 2026 under a tribal model. Major brands include DraftKings, BetMGM, FanDuel and Caesars, although availability varies by state. See our US online casino guides for local laws and licensed operators.

Canada

Canada’s online gambling market is regulated at provincial level, with Ontario and Alberta now operating competitive regulated iGaming markets open to private operators. Ontario launched its market in 2022, while Alberta followed in July 2026, giving players access to licensed online casinos, sportsbooks and poker sites. Rules and availability continue to vary elsewhere in Canada. See our Canadian online casino guide for locally available operators and regulations.

Great Britain

The UK remains one of the world’s largest and most tightly regulated online gambling markets, with casino operators required to hold a UK Gambling Commission (UKGC) licence. Players have access to thousands of slots, live casino and table games, although tighter player-protection measures now include online slots stake limits and financial checks for some customers. See our guide to the best UK online casinos for more information.

India

India has introduced a nationwide ban on online money games, including real-money casino games, under the Promotion and Regulation of Online Gaming Act 2025. The legislation applies to games of chance and skill and also restricts advertising and payment processing connected to prohibited games. Esports and non-money social games remain permitted. See our India online casinos guide for more information on the current laws and restrictions.

New Zealand

New Zealand is moving to a regulated online casino market under the Online Casino Gambling Act 2026. Up to 15 operators will be permitted to hold local licences, with the new regime expected to be fully operational in 2027. During the transition, existing offshore operators can continue under specific conditions. See our New Zealand online casino guide for the latest licensing status and locally available casinos.

Ireland

Ireland has a regulated online gambling market with a range of major casino brands available to players. The Gambling Regulatory Authority of Ireland (GRAI) oversees the country’s new licensing regime under the Gambling Regulation Act 2024. Casino availability and payment options vary between operators. See our dedicated Irish online casino guide for local recommendations and more information on licensing and regulation.

South Africa

South Africa has a complex provincial licensing system. Licensed bookmakers offer online casino-style products including slots and live dealer games, while offshore casino operators do not hold South African licences. See our South African online casino guide for the full legal position.

Best International online casinos

The online casino industry is diverse but not every country has regulation surrounding online casinos. Rest assured there are plenty of good International online casinos that accept players from right around the world. Even if you are in a country where online casinos are banned there will be an international online casino that will take your bets. Remember, when looking for an International online casino, do your homework and only choose casinos with strong reputations.


Step by Step: Registering and playing at online casinos

There are many things to take into consideration when choosing an online casino. Is it legal to bet at online casinos from your home country? What deposit options are there for people in your region? Is the casino licensed? Do they have the games you want? What is their reputation like? Are there any reports of slow cash-outs? What type of platform are you playing on?

As you read above, there are many different laws for online gambling in different nations. If you are unsure about the status of gambling in your country, do some research. It pays to be aware of the rules. You could be in a country with a great regulated gambling industry, so why accidentally play at an offshore online casino. Our tables are geo-targeted and will only show online casinos you are able to sign up at.

While registering at online casinos can have slight variations depending on your location, generally the process follows a similar path no matter where you are in the world. You will fill in a digital form with details like your name, date of birth, address, email address and telephone number. Often your details, using digital means, will automatically verify your account, passing various Know Your Player (KYC) laws in certain countries. Other online casinos will require you to send in proof of identity if they can’t verify your account automatically.

Real money online casinos will often have welcome bonuses, or offers available to new players. Be very wary though, these often have huge wagering requirements, making them next to worthless. However, casino bonus offers can be a great way to have a look at a casino, and extend your gameplay. Some casino bonus offers are even great, and are not a scam to get your business. Use websites like the World Gambling List to seperate the good offers from the bad.

One of the most important parts of playing at online casinos is funding your account, but this has become increasingly easier as payments have digitalised. Where you are in the world and what currency you wish to play in are all major factors in funding your account. There is more information about casino payments below.

online casino games

Many online casinos allow you to browse their games before you sign up, which gives a fair idea of what they have to offer. Some casinos will use multiple software providers and have more than 2000 games, while others will stick to one platform. Popular games available at the best online casinos include live dealer classics like blackjack and roulette, online slots and video poker.

The best online casinos will all have customer service departments around the clock. While some queries may take time to solve, all of the casinos we advertise in this guide have extensive customer service options, including live chat and telephone.

Online casinos will allow you to cash out any winnings with many different payment methods. While some online casinos will restrict you to the payment method you used, for withdrawals, generally bank transfers, web wallets and even cash withdrawals are popular. Some players can use cryptocurrency withdrawals, although these are excluded in key gambling markets like the UK and Malta.


Online casino games

While nothing quite matches the thrill of walking on to the gaming floor at one of Las Vegas’s many casinos, the online casino game selection is improving all the time. The selection of live dealer games is a welcome addition and has heralded the true arrival of online casinos.

Online Slots Pokies

Slots

Known as pokies in some quarters, slots are one game which is genuinely better on your computer. The 3D games are life-like (or magical) and the progressive jackpots available on the internet can sometimes top $US10 million. Popular slots providers include Betsoft, Playtech and Net Entertainment. Explore the history behind slots as well as different strategies and types in our extensive slots guides.

Blackjack

Blackjack

Perhaps the No.1 casino game in the world, blackjack is readily available to online players. There are various versions from many different software providers. Several of our favourite blackjack titles include Ezugi Live Dealer, Pragmatic Play Live and Evolution’s titles. Online blackjack for real money can be played in most places globally, with most gambling sites stocking at least several versions of it.

Roulette

Roulette

Roulette, or The Devil’s Wheel, is one of the all-time classic casino games. Online you can play a large selection of live roulette titles, including some you wouldn’t find at a land-based establishment. Roulette at online casinos, while catering for high rollers, also has games which don’t price out low-limit players, unlike some land-based gaming venues. Online roulette for real money can be played in most places globally

Poker

Poker

If you want to play casino poker you can, including games against the dealer such as Casino Hold’em and Caribbean Stud Poker, but it’s the community games that have become insanely popular. Online poker tournaments run daily at various levels at many different operators. Poker websites such as Pokerstars, WSOP and GGPoker are where most of the action is at in 2025. You can learn about the ins and outs of poker here, or delve into the online poker world.

Pontoon

Pontoon

Pontoon is a very similar casino game to blackjack in a lot of aspects, however there are a few key differences. Pontoon allows players to double down, before they play out the hand, taking multiple hits or “twists”. This means players can double down after they receive a third card. Online Pontoon games are commonly found at the top casinos online, with it possible to play in both live dealer and and RNG format.

Caribbean Stud

Caribbean Stud

A poker variation where players bet against the dealer, rather than against each other. Caribbean Stud has adapted extremely well to the online world, with many casinos stocking this as a live game. Apricot, Playtech and NetEnt all have multiple versions of Caribbean Stud available in both RNG games and live dealer. Read our guide to Caribbean Stud for more information.

Baccarat

Baccarat

Baccarat is one of those games where it doesn’t really matter if you are playing at home or at the Bellagio. The house edge is low, the stakes are usually high and the rules are simple. Online it’s exactly the same with live dealer and RNG-based versions available. One of the best things things about playing baccarat at online casino sites is that often the table limits will be more friendly to those of us who don’t have massive bankrolls. Read more about baccarat.

Craps

Craps

Craps is one of the oldest casino games and is really quite simple despite appearing busy and confusing when playing live. Without proper guidance and understanding you can lose money quickly when playing, so be sure to read our how to play Craps guide. Craps is not found as frequently at online casinos, as it is in land-based venues with it often much more possible to play at RNG version, than a live dealer Craps game.

Bingo and Housie

Bingo/Housie

While bingo, or Housie, as it is known in some places, is not as widespread as slots, there are plenty of online casinos that stock a few versions of this game. Traditionally played at places such as scout halls, bingo has evolved into a popular online casino game, with both RNG and community games available to players. Online bingo is particularly prominent at UK casinos, with this game played right across the country. Some of the bigger online casinos with Housie include 32Red and Royal Vegas.

Keno

Keno

Another game that is more commonly found at land-based gambling venues, keno has been adapted for internet casinos. You can play both live games (where you watch a live video of someone picking the numbers) or you can play via an RNG game, which still allows you to pick your numbers, but the balls being drawn are done via random number generators. The aim of the game is pick as many of the drawn numbers prior to the game. The more numbers you get, the more cash you win. Read more about playing keno online.

Casino War

Casino War

Always regarded as one of the easier games at online casinos, Casino War basically pits dealer against player. If your card is higher than the dealer’s you win and vice versa. You can also bet on a tie. You will find Casino War at many of the top online casinos, but if you are looking for it in live dealer you are probably out of luck, because we haven’t seen it before. Having said this, online casinos are rapidly evolving, so don’t be surprised if a live version of Casino War springs up soon.

Sic Bo

Sic Bo

Of Asian origins, Sic Bo has been adapted into many Western casinos. Sic Bo is a dice game where the player bets on the possible outcomes of the three dice thrown down by the dealer. The origins of Sic Bo date back to the ancient Chinese, with it now a staple in South-East Asia. Online you will find it in live format but generally only at casino sites targeting Asia. If you are desperate for your Sic Bo fix you will find it in RNG format at most of the best online casinos.

This is the big advantage online casinos have over their land-based rivals — they don’t have big overheads so they can afford to give more back to the customer. And while online casino bonuses usually come with heavy wagering requirements, you can walk away a winner from using a bonus. Things to look out for include ridiculous terms like a $10 cap on winnings or anything over 50x turnover requirements.

Mobile devices are now the no.1 way people wager at online casinos in 2026, with most gambling sites boasting fully responsive mobile websites, while brands in regulated markets often have apps available for Android, iOS and increasingly Huawei smartphones and tablets.

The casino games selection at mobile gambling sites generally mirrors that of the desktop computer, with live dealer, slots, crash games, video poker and even draw-based titles working well on smaller screens.

The online slots selection is usually top class at mobile casinos, while RNG table games are extremely functional. As the mobile market grows, expect the game selection to become stronger and stronger.

Mobile casinos now have a huge range of video poker games, blackjack games, roulette games and pretty much any other key game that you might find at an online casino. These mobile casino games are designed to run smoothly on WIFI, 4G and 5G connections and function much the same as they would on desktop.

Many online casinos offer free-play or demo versions of their games, although some operators require players to register an account before accessing them.

Probably the most common way to play at online casinos on mobile devices is via apps, with many of the top casinos boasting Android, iOS and Huawei apps.

Online casino apps

Depending on which country you are in you may be able to download market apps for various online casinos from places such as the Apple App Store and the Google Plus store, which is for Android users.

Some countries, such as Australia, have legislation against real money gambling apps. If you use Android and want to download an app in a country where they are banned you may be able to download a non-market app directly from the casino.

Android casino apps

Android casino apps

Android casino apps are more common than those of their chief rival Apple. This is because they can be marketed as third party applications, meaning they don’t have to pass stringent tests to get into the Google Play store — they can simply be downloaded from the online casino’s website. Rest assured if the online casino has regulation, their app will still have to abide by the strict rules placed on them even if you are downloading it directly from the gambling company.

iOS Casino Apps

iOS (Apple) casino apps

iOS casino apps will only be found in a country that has gambling regulation, or the one exception is if there is no regulation at all, which includes countries like Canada and New Zealand. Basically we are at Apple’s mercy when it comes to playing online casino games on iPhones or iPads, with no way to install third party casino apps, unless you jailbreak the phone.

Android casino apps

Web apps

A web app is a simple icon on the desktop of your phone or tablet that links you directly to an online casino’s website. Basically it is just a shortcut to create quick access to your account, with it just loading the web page on your browser. It is possible to create web apps quickly on both Android and Apple devices.

Huawei AppGallery

Huawei apps

Huawei casino apps are available in various regulated markets across the world. These include African countries like South Africa, many Asian countries, and across Latin America. Huawei casino apps are downloaded directly from the AppGallery, or directly from gambling operators, with these devices allowing non-market apps.


Online casino licensing jurisdictions

Gambling at online casinos is done by millions of people, with most of them safely and securely enjoying their gambling experience at a website licensed in a respected jurisdiction.

What this means is there are countries which license and regulate online casinos, the vendors forced to abide by certain restrictions to operate. For instance, online casinos based in the United Kingdom must be audited by eCOGRA, which is an independent regulatory body which tests games for fairness and resolves disputes.

If an online casino is based in Malta it does not necessarily mean it is restricted to serving this country. Many of the biggest online casinos are based in Malta and serve countries including England, USA, New Zealand and many others.

Some online casinos do restrict their services. For instance, many casinos do not service the USA because of the strict federal laws surrounding online gambling. To confuse matters further there are casinos operating outside this somewhat confusing law.

Lets take a look at some of the more trustworthy global gambling regulator

Trustworthy casino licens. sing:

While there are plenty more countries providing online casinos to the world, not all of them operate from savoury licensing jurisdictions. Eventually we will have more in-depth reviews of each of the places providing casinos, but for now here are some of the more respected places they are based.


Deposits & withdrawals at online casinos


The methods involved in depositing money at online casinos are plentiful, with most having full banking facilities for countries they serve. This means deposits can be made via credit and debit cards (Visa, MasterCard, Diners Club etc), bank transfers (some local, some international), web wallets (Neteller, Skrill etc) and other forms of payments specific to certain countries. In Germany, for instance, there is a company called Giropay which processes payments to casinos through accessing your online bank account.

Withdrawals work in a similar manner to deposits with the casino usually processing payments within 24 hours of requesting it, mostly quicker. Depending on the method you have selected to withdraw funds it could take a few business days for the cash to be yours. If you are using a web wallet or some other withdrawal methods you may get your money quicker, or even instantly.

Banking transactions at the safest online casinos are usually safeguarded with 256-bit SSL encryption technology. This is the best encryption available for keeping funds safe; it is in line with what major banks around the world use.


Online casino software

Online casino software is provided by many different developers, with many gambling sites using a mixture of providers and integrating these games into one platform.

Traditionally online casinos were powered by just one software developer, with pioneers like Microgaming and Playtech powering most of the early gambling sites.

But now technology companies have platforms that casinos can take and basically integrate any games into it, which means you could find casinos with 50 or more software providers.


Online casinos history

Online gambling has grown from a niche internet experiment into a multibillion-dollar global industry, with online casinos, sportsbooks and poker sites now competing directly with traditional gambling venues.

The growth of online casinos has been rapid and forced governments around the world into playing catch-up, with the evolution of them staggering, given they have only been mainstream for under two decades.

From basic websites to modern online casinos

The first online casinos appeared in the mid-1990s, offering a small selection of basic casino games. Software developers including Microgaming, Playtech and NetEnt helped drive the industry’s early growth.

Faster internet connections, smartphones and improved gaming technology transformed the experience. Players can now access thousands of slots, table games and live dealer games streamed directly to computers and mobile devices.

Online gambling regulation

Governments gradually began regulating the industry, with established licensing regimes emerging in markets including the UK and across Europe. Malta, Gibraltar, Curaçao and other jurisdictions also became important licensing centres for international operators.

The picture remains very different from country to country. Some governments regulate online casinos, others restrict particular products, while some prohibit them altogether.

Safer gambling and financial controls

The rapid growth of online gambling has also increased regulatory scrutiny. Licensing authorities increasingly require operators to monitor player behaviour, provide responsible gambling tools and intervene when customers show signs of gambling-related harm.

Anti-money laundering and customer verification requirements have also become a major part of online casino regulation, with operators expected to verify customers and monitor suspicious transactions.

The rise of regulated US online gambling

The United States has become one of the industry’s most important growth markets. Legal online sports betting expanded rapidly following changes to US law in 2018, while a smaller number of states have also regulated online casinos and poker.

The COVID-19 pandemic provided another major boost to online gambling as land-based casinos closed and consumers increasingly turned to digital entertainment.

Today, online gambling is firmly established as one of the biggest parts of the global gambling industry, with regulation and technology continuing to shape how and where it grows.


Online casino languages and currencies

With the global online casino landscape rapidly evolving, one of the biggest pros has been that they are catering to specific or multiple markets. This means that often a casino will be hosted in multiple languages and cater to many different currencies. While the World Gambling List is written only in English at this point, we will point you in the right direction if you are searching for a certain language to do your gambling in. For instance, most European countries that do feature regulation will have casinos “facing” in their direction which means they will be in Swedish, Dutch, Spanish or many of the other languages spoken. You can read our casino reviews for further information on what languages are supported by each casino.

Most online casinos will outsource their payment processing and receive a global solution, which means they will have a stack of currencies available to choose from during the sign-up process. In short, all this really means is that your account balance will be displayed in your chosen currency, often corresponding to the country that you live in. However, if you are from a country without regulation or a smaller nation you may have to deposit and convert your money to another currency. Often there is a small conversion fee to do this, but it usually is less than a few per cent, or a small set amount, and then you will see the balance of your account in a popular currency such as the USD or Euro.


Online casino laws

Online casino laws vary from country to country

Laws surrounding online casinos vary greatly from country to country which means it is hard to determine whether you specifically are legally allowed to play at an online casino. Even if you legally are not allowed to play at an online casino, it doesn’t mean you can’t. There are very few cases globally of a punter receiving the raw end of the stick from authorities for playing at an online casino; generally it is the operators themselves who are targeted. In the few cases where players have been prosecuted it has been in countries such as the United Arab Emirates where religious beliefs are backed up by stringent laws. Even now though casinos based “offshore” operate and accept players from countries who have strict gambling laws. You could break the countries’ laws down into three categories:

  • White market
    Countries like the UK and Malta are considered white markets and have regulated, legal gambling options. Often countries classified as grey markets will also be targeted by white market operators because there will be no sanction for accepting players from here. Other countries with legal “white market” online casinos include South Africa, Canada and many US states.
  • Grey market
    Countries like Canada (with the exception of Ontario) and New Zealand are considered grey markets, which means that there are no laws stopping offshore companies from targeting casino players, yet there are few or no regulated casinos by the specific country. Grey markets are like gold for gambling companies because they don’t have to pay tax to the country the players is from.
  • Black market
    The illegal online casino industry is booming and worth billions of dollars. Countries like the USA, Australia, China and Malaysia are black markets and have thriving online casino scenes. Licensing bodies such as Curacao and Costa Rica allow their operators to target black markets which often forces the hand of governments around the world to take action and offer regulated gambling themselves. Governments around the world, including Australia, have used IP blocking to stop online casinos from serving Australians, although mirrors of the website tend to spring up at a new domain quickly.

Staying safe & customer service at online casinos

If there has been a theme in this article it is to do your research before committing a lot of money to a casino. It pays to query customer service before you deposit to make sure there is someone there. You can always make a small deposit and then withdraw it to make sure the process works smoothly.

Customer service at online casinos can be reached via several methods (obviously depending on what casino you are playing at). There are options such as email, live chat, Skype and sometimes even local numbers for players to call. This is definitely one area of a casino to have a look at before you commit real money.


Types of online casinos

When you first start out playing at online casinos you will find a myriad of terms thrown at you, like download casinos, instant play casinos, mobile casinos and many more. While they are all essentially the same products, these are some of the different types of casinos are described:


Trusting online casinos

With the rise of online casinos and the increased use of personal and credit information online, many people are confused about just how much to trust them and online merchants in general. While those of us more experienced with these factors know of the low risk, high convenience of these services, changing online gaming laws and the sheer number of online casinos available make being informed even more important than ever.

While many new players at online casinos may feel that giving information may be risky or unsafe, this just is not true. Online casinos, like any other customer services, depend heavily on reputation and the bad press associated with any dishonest dealings would never be profitable in the long run. With proper research, a player should have no trouble at all finding a reputable, honest online casino to open an account with.

The use of the internet has increased much faster than legislation can keep up with. As a result, online casinos must adapt and change with laws in order to remain in business. This is a great benefit to players, as online casinos seek to play by the rules in order to stay in business, meaning more security for the consumer.

Deciding if an online casino is worth trusting is often a simple matter or reading honest reviews and determining if it is licensed. A quick search engine query should turn up several reviews from independent sources (if it doesn’t, the online casino probably hasn’t been around long enough to build up a reputation).
A reputable online casino will take strong steps towards separating itself from lesser companies, being fully licensed and using trusted, quality programs.

Always remember that online casinos are just as much at risk as its clients. With thousands of people depositing and withdrawing cash, online casinos take every precaution to properly identify all players and clients.

What this means for the average player is that their information is always safe, and their money will only be removed or altered at their own discretion.

With the technology involved with online casinos, some people worry that the temptation to alter odds or prevent players from winning may prove too much for the online casino staff.

But, even if an online casino took steps to illegally cheat players, with the chance of having their operation shut down and risking fines and imprisonment, would the added funds really matter when players began to leave in order to play in a more fair location? No.

Even if an online casino made the foolish decision to alter their games’ odds, any success would be short lived, as reputable online casinos are independently audited. What this means is that winning payouts will be calculated over time to determine the house advantage, and that the online casino has been adhering to it.
In short, while it is theoretically possible for an online casino to cheat, it would never be profitable.

Best Online Casinos

Commonly asked questions about online casinos

Working in the online gambling realm, it’s crazy how many questions we get asked constantly. These range from things like are there online casinos in my country? To, how old do I have to be to play at an online casino? Here are the answers to some of the more common questions we get asked about online casinos.

  • What is the best online casino?

    We must get asked this question about online casinos at least once a week, and there is no real definitive answer. There are some great UK casinos like Leo Vegas and Mr Green, but we can’t all sign up at them. Instead it comes down to individual answers like the best casino for players in a certain country is x casino. If online casinos are banned in your country it gets even murkier as to what is the best online casino.

  • Can USA citizens sign up at online casinos?

    The USA went through a period of great change to its gambling laws in 2018, with most states now either actively working towards regulating the gambling industry, or have done already.

  • What US states have regulated online casinos?

    While most states are considering legalising sports betting in the USA, online gambling has been slightly slower. Currently the USA states with regulated, or do have legislature in place to regulate, online gambling are New Jersey, Nevada and Delaware, with California and Pennsylvania progressing well in their bid to regulate the industry.

  • How do we know games at online casinos are fair?

    Online casinos that have strong regulation will only use licensed casino software companies, which means they will be heavily audited by third parties like eCOGRA, which tests things like random number generators for fairness. There are two main types of software that you will find at online gambling sites, with these being the licensed and regulated games from companies like Microgaming and Playtech, while the other is from companies like RealTime Gaming, which allows online casinos to alter the source code of their games — in essence they don’t provide player assurances after the game has left their grasp. Instead when playing at a RTG casino, or one like it, you should be sure that site you are playing at has a strong reputation, with good reports from players.

  • What is the best casino game?

    This really does come down to preference. All we will say, is that online casino games are improving all the time, with 1000s of real money slots available and many variants, that you would not find in brick and mortar casinos, of live table games available behind the virtual doors of good casinos. In total many of the best online casinos have over 2000 games in total.

  • What are live dealer games at online casinos?

    This is when a video feed of a real live casino game is streamed to your computer or mobile device, while you place bets on a virtual table. The beauty of playing live dealer online casino games over live in-the-flesh table games is that there is generally table limits to suit all types of players, you won’t be priced out playing. The sheer variety of games is also outstanding when talking about live casino games.

  • Is online or casino gambling better?

    While this question comes down to so many factors, we’ll say straight off the bat, that it’s very hard to beat the atmosphere of a land-based casino — we’ve played at the Bellagio and Caesars Palace — we know how much fun it is. But the answer is not this straight forward — if you’re purely looking for the best odds and convenience, online casinos might be for you. To give you an example, in most places in the world a slot machine will pay between 84 and 90% of the money put into it, while at most online casinos slots will pay out upwards of 96%.

  • Why are online casinos payouts better than land-based casinos?

    This is because there are less overheads and more competition in the online gambling realm. For instance you don’t need bar and wait staff at an online casino. This means online casinos, with an eye on shading their competition, give more back to the players and use it as a selling point to lure new players.

  • How long do payouts take from online gambling sites?

    When you win, often it can be frustrating waiting to get paid from an online casino. How long it takes will depend on what your situation is. For instance if you are in the US and bet with an offshore company the payout might take up to 10 days to hit your account. If you in the UK and play at an online casino licensed here, you realistically can have your cash within two days. Some online casinos are even beginning to process cash-outs instantly.

  • Are there any online casinos with a betting site as well?

    Yes there are many gambling sites that have dual functions. This includes some of the biggest names in the industry, like William Hill, Bet365, Guts.com, Betsson and LeoVegas. While we wouldn’t say most online casinos have some sort of sports betting offering, the number is increasing yearly as third-party platforms become more accessible for gambling companies.

  • How do online casinos make money?

    All casino games have a house edge, and if they don’t there is a small percentage taken from each bet to cover the house costs. For instance a table game might have a house edge of 0.5% which is the best you can hope for when using basic strategy on a blackjack table. This means 99.5% of the money put into the game will be returned to players. The house edge doesn’t factor in the stupidity of the players, so in most cases an online casino is earning at a much greater capacity.

  • What is the biggest online gambling market in the world?

    Right now it is hands-down the United Kingdom. The UK is the biggest regulated jurisdiction in the world and has hundreds of licensees that serve various markets all over the world. Many online casinos will hold multiple licenses, but the biggest will generally hold that magical United Kingdom Gambling Commission seal of approval. Having said this the United States and to a lesser extent India (because the economy is not worth as much per head) are the sleeping giants of the online gambling industry. The USA has only just began regulating online casinos in most states, while India and its population of close to 1.5 billion is yet to put anything in stone, but have began discussions about regulating some forms of gambling.

  • Do men or women gamble more?

    Gambling has traditionally been a man’s domain, but online casinos have began tapping into the female mindset. For instance do you thing bid budget Microgaming slots releases like Bridesmaids are targeted towards men, I don’t think so. Many of the latest studies do however show that men gamble more, spend more and are more prone to problem gambling, despite this gap decreasing in recent times.

  • What is a casino bonus?

    An online casino bonus is a perk for a player, usually given when you open a new account. These casino bonus offers can come in numerous forms, including no deposit bonuses, matched deposit bonuses, free or extra spins and anything else the website can dream up. Be aware there are wagering requirements generally attached to online casino bonuses, which in some cases, can make it very hard to actually turn a profit from your bonus money.

  • Can you play casino games for free online?

    Yes you can, most online casino software companies, will also give their licensees permission to allow players to play their games for free. Often websites like this one will also host free versions of slots and RNG table games. However there are no live games available in freeplay mode — this would cost the casino sites too much money.

  • Are online casinos legal in Australia?

    Australia has banned online casinos, as of 2017, with an update to the Interactive Gambling Act closing a loophole which allowed offshore gambling sites to target Australian residents. In 2025 there are still many online casinos that target Australia, but these sites are as reputable as the ones that have now departed this massive gambling jurisdiction.

  • Are there are any adult casinos?

    You would be surprised how often we get posed this question by online casino players. Maybe minds are straying back to when the Microgaming Playboy Bunny’s were first released. Well the good news is there are adult casinos, but the bad news is we choose not to promote them on the World Gambling List.

  • What time is best to play at online casinos?

    This poses a few different questions. If you are a slots player, online casinos are 24/7 and you can pop onto your phone or computer and play anytime. If you are looking for live games you may need to do a little bit more homework, although there are plenty of around-the-clock options if you are based in the right place. Look at it like this, if you are in the UK and play at an online casino based there at 7pm at night you are likely to find plenty of live tables open for business. However if you visit this same casino at 2am UK time you might find the dealers have gone home for the night. The good news is there plenty of online casinos that will have live games open right now, you just have to find them.

  • Do I need to use my real name when playing at an online casino?

    As a general rule, yes you do need to use your own identity when signing up at an online casino. This is because you must prove your identity, with this known in some places as Know Your Customer (KYC). Basically online casinos are obliged, through agreements with their regulators and the country’s they operate in, to keep tabs on the money and who is spending it to stamp out things like money laundering and fraud. If you can’t prove your identity online casinos could stop you from withdrawing any winnings and report your account activity to the relevant authorities.

  • What online casino has the best slots games?

    This is again dependent on what you are looking for, but rest assured if you play at an online casino with any of Net Entertainment, Playtech, Microgaming or Betsoft software you will find some great slots games. Often online casinos will have a variety of slots providers supply them with games, which means you can find a great array of slots titles. For instance SlotsMillion has over 2300 real money slots available.

  • Is online gambling legal in New Zealand?

    It’s not illegal is probably the correct answer here. Basically New Zealand does not have any laws surrounding online casinos in operation, other than that they cannot operate there. This however does not stop many of the best online casinos from operating in New Zealand from offshore locations. There are not many gambling sites that won’t accept NZ dollars and your custom.

  • What is the oldest casino online?

    There are plenty of online casinos that have been around since the late 1990s, with these including Royal Vegas Casino, which we understand is the oldest left still online.

  • Why can’t I access online casino apps from my country?

    Often regulation will stop online casinos from putting their apps in the Apple App store, and with no third party apps available on iPhones, you probably will have to just play in your mobile browser. If there is regulation, or no regulation stopping online casinos, in your country it’s likely you can download iOS apps. Android users are a in a different situation, with these devices allowing third party downloads, which means that you can download gambling apps directly from the company that offers it. Always do your homework before downloading a gambling app to an Android device, because there is far less restrictions placed on their operations.

  • Why can’t I use Paypal to deposit at online casinos?

    Paypal is one of the biggest processors of gambling deposits in the world, however they only operate in regulated markets, or ones where there are no laws banning online casinos. It’s highly likely that if you can’t see Paypal as a deposit option at a UK or MGA licensed casino it means Paypal won’t process gambling payments in your country, in accordance with local law. If you are in a country where there is regulated gambling, read Paypal online casinos for further information, including what countries cannot use Paypal.

  • What are my chances of winning at online casinos?

    This really does come down to the individual, what game they are playing and whether you know what you are doing. Online casinos have a return to player (RTP) rate and this means they give back a set percentage of all money put into the online casino, but rest assured the casino always wins in the long run (How do casinos profit?). An example is if you follow the best basic strategy when playing blackjack you should have a RTP of close to 95%. Obviously ladyluck still has her say, so always set yourself limits on how much you are willing to lose in a session. Also set yourself an upper limit, where you walk away a winner, before squandering your hard work on the slots or tables.

  • Which are the highest paying online casinos?

    Online casinos set their own return to player rate (RTP) and this determines how much money they pay back to the casino. This RTP rate will vary from game to game, but at the end of it, the casino will be able to give you a figure, which on average is anywhere between 85% and 95%. All of the top online casinos on this page are 92% and upwards RTP. Things can get murky if you are playing at online casinos with lower standards of regulation than the sites we advertise. For instance RTG casino operators have control over individual slot games RTP which means it could vary greatly from site to site.

  • Are mobile casinos safe?

    Security protocols at the top online casinos mobile sites is as strong as their desktop version. Basically if an online casino has a good reputation, it will also encompass their mobile casino as well. Staying safe when gambling on mobile largely comes down to your WIFI connection — if that is secure you should be fine as long as the casino is a legitimate gambling site.

  • What is eCOGRA all about when gambling online?

    eCOGRA is a body that verifies that online casinos are treating players fairly. If you see a casino with the eCOGRA tick of approval, it’s an affirmative sign that they are a legit business. The eCOGRA (eCommerce and online Gaming Regulation and Assurance) body makes sure that casino, including things like random number generators and banking practices, are at a high standard. This eCOGRA symbol is one of the strongest indicators given to a player in the online gambling industry.

  • What does the future hold for online casinos?

    This is a question that gets pondered a lot in the gambling industry and in a lot of ways the future is already here for online casinos. Already several online casinos have created Virtual Reality experiences for their players. Basically you put on some fancy goggles and then it seems like you’re walking around a casino — where you can choose the game you wish to play. If you want to check out a great virtual reality casino, visit SlotsMillion.com. Other advances we can expect in online gambling is the continued growth of mobile, with the products available on handheld devices getting better by the day. This is partly down to the improved speed of internet connections, but also a greater emphasis on development from the iGaming software companies.

  • What casino card game has the best odds?

    This really does depend on a few factors, including the variance of the game you are playing. However as a general rule baccarat is regarded as the mainstream card game with the best odds. This is why it is so popular with high rollers, particularly in Asia. Baccarat’s house edge can be anywhere from 1.01% to 1.24% at online casinos. Video Poker is also another game with a low house edge, that is popular at online casinos.
