Best online slots sites
Playing slots online is better than playing slots at a land-based gambling venue. Yes, you read that correctly. We believe online slots offer a better overall experience than your average machine at a casino, club or pub.
There are several factors that led us to that conclusion. We looked at payout rates, game variety, progressive jackpots, bonus features and, of course, the convenience of being able to play from your desktop computer, smartphone or tablet.
While online casinos obviously lack some of the social atmosphere found at a land-based venue, players are often rewarded with a far greater choice of games. The biggest online casinos now offer thousands of slots from dozens of software developers, including everything from classic fruit machines and progressive jackpots through to Megaways, Hold & Win and Bonus Buy titles.
Online slots also tend to be more transparent. Most games publish their RTP (Return to Player) percentage, allowing players to compare different titles before they play. Many of the best online slots feature RTPs of 96% or higher, making them competitive with their land-based counterparts.
The online slots sites you can personally join will depend on the gambling laws where you live. Countries such as the United Kingdom have highly regulated online casino markets, while other jurisdictions have their own licensing requirements and restrictions. It is always important to check your local laws before signing up with a real money slots site.
Modern slots casinos are also built with mobile players in mind. Most online slots sites can be accessed directly through your web browser, with no download required, while many operators also offer dedicated Android and iOS apps. Whether you’re playing from a desktop computer at home or spinning the reels on your phone while on the move, accessing your favourite slots has never been easier.

The mobile side of online casinos has exploded over the past decade and is now the preferred way many players enjoy slots and other casino games. Millions of people around the world play real money slots on their smartphones and tablets every month, with online casinos investing heavily in mobile-friendly platforms and apps.
The convenience associated with mobile online slots remains its biggest attraction. Not everybody lives near a casino or slots venue and, even if they do, many players would rather spin the reels from the couch, on the train or while travelling. Modern mobile slots offer the same gameplay, jackpots and bonus features found on desktop, with many games now designed specifically for smartphone screens.
Whether you use an iPhone, iPad or Android device, you will have access to thousands of online slots. Most casinos now offer instant-play mobile websites that allow players to register, deposit and start playing directly through their web browser, with no software download required.
Many online casinos also have dedicated mobile apps available, although availability will depend on your location and local gambling regulations. In regulated markets such as the United Kingdom, casino apps are commonplace, while players in other jurisdictions may be limited to browser-based gaming.
The quality of mobile slots has improved dramatically in recent years. Today’s games feature HD graphics, smooth animations, progressive jackpots and feature-rich bonus rounds that perform just as well on mobile as they do on desktop. Combined with fast mobile-friendly deposit methods such as Apple Pay, Google Pay, PayPal and online banking, playing slots on the move has never been easier.

You are doing well if you can find an online casino that doesn’t have a good selection of slots. After all, they are easily the biggest money-spinners for casinos, both online and on land.
Where you are based will determine the range of games and casinos at which you can play. For instance players from the USA are heavily restricted by their tough gambling laws. This doesn’t mean you can’t play at online casinos, it simply means you need to work a bit harder to find one.
Places such as the United Kingdom, Sweden and Norway (this is just a small sample) have regulated the online casino industry and in turn allow casinos to operate in a transparent environment. For many countries, such as Australia, there are not laws addressing online gaming. While it is not legal to base online casinos out of Australia it is legal for Australians to gamble at casinos based out of other countries. It’s a similar story for much of the world.
Each online casino will have a software provider (there are several exceptions to this, with games or some games made in-house) or multiple places from where they draw their slots. For much of the world Microgaming is the best-known platform for online casinos, although companies such as BetSoft, NetEntertainment, Playtech and RTG hold their own.
The software used by casinos should be a decisive factor in choosing where to play slots. You want to play at casinos with respected software companies that are audited by independent third parties such as eCOGRA and similar bodies. Just like casinos, the software is generally licensed in a certain jurisdiction such as Malta (Microgaming).
The software also determines what slots games a casino will have. Unless you beat the system (think bitcoin casinos), Americans cannot play at Microgaming casinos because the software company is not allowed to operate in America under its Malta licensing agreement. Another example is Aristocrat Leisure’s online arm, which is not allowed to operate in Australia because the company is based out of Sydney.
Online slots promotions & free spins
One of the best things about playing online slots is the range of promotions, bonus offers and free spins available to players. Most online casinos offer a welcome package for new customers, which may include a matched deposit bonus, free spins or a combination of both. In this section of our guide we present the latest online slots promotions and bonus offers.
Beyond welcome offers, many slots sites now run ongoing promotions including cashback deals, reload bonuses, slot tournaments, prize drops and VIP rewards programs. These can provide regular players with additional opportunities to boost their balance or earn extra spins.
It is important to remember that most online casino bonuses come with terms and conditions attached. Wagering requirements, game restrictions and maximum withdrawal limits may apply, so players should always read the fine print before claiming a promotion.
Some of the most common slots bonus offers you will see online include:
Casino welcome packages:
Joining an online casino can be a rewarding experience for slots players, with most having welcome packages. These could be a matched deposit and free spins combination or just one of these. These slots sign up offers are a great way to boost your bankroll or even have a free look around your chosen casino site.
An example of a casino welcome package: 100% up to $100 + 100 free spins.
Free spins offers:
Free spins offers are essentially giving you a free hit on a slots game. Sometimes slots free spin offers can be given to a player just for opening an account. While other times a player might be rewarded with free spins for hitting a VIP goal, being a loyal customer or maybe even just be given them via email in an attempt to get you to login to the slots site.
An example of a free spins offer: Open a new account and receive 50 free spins no deposit.
Reload bonuses:
A bonus awarded on deposits made after the welcome offer has been used. Reload bonuses are commonly given to players who make more than one deposit, and usually involve a percentage match or deposit bonus. But we have seen free spins incorporated into these offers in times gone by.
An example of a reload bonus: Deposit 100 units of your currency and have it matched 100% bonus.
Slots cashback offers:
Casinos will often give players cash back on losses, as a way of enticing players to keep playing at the same slots site. Often part of VIP or Rewards Programs, slots cashback offers are a great way to get something back if you are a regular at online casinos and they are perfect for slots players, with any bonus given to you generally having its wagering requirements cleared at 100% when playing these games.
Example: Receive 5% cashback on slots losses up to 100 units of your currency.
Slots tournaments
Slots tournaments are not specifically a promotion, but they are a great tool for casinos to attract players to gambling websites. While they have different structures and often work in different ways, depending on the slots site, the general gist is the more you play the more points you score the higher you finish on the ladder – securing yourself cash and prizes. Often slots tournaments are based on a specific slots developer, meaning you could participate in the same promo in various jurisdictions and gambling websites. For instance, Playtech often runs slots tournaments in markets they are regulated in.
VIP & loyalty programs
Loyalty programs vary from casino to casino, but slots players are often among the biggest beneficiaries. Most VIP schemes reward players with points based on their wagering activity, allowing them to move through different tiers and unlock additional benefits along the way. The higher your VIP status, the greater the rewards are likely to be. Depending on the casino, these perks can include cashback offers, free spins, bonus funds, faster withdrawals, dedicated account managers and invitations to exclusive events. Some of the industry’s most generous loyalty programs have even rewarded high-value customers with luxury holidays, electronics and cars.
When you accept an online slots bonus, you are also agreeing to the terms and conditions attached to it. These rules are designed to prevent players from simply claiming a bonus and immediately withdrawing the funds, while also helping casinos protect themselves from abuse. Unfortunately, some bonus terms have become increasingly restrictive over the years, which is why we do our best to only recommend slots promotions that offer genuine value to players and a realistic opportunity to win real money.
Some of the most common slots bonus terms include:
Turnover or rollover requirements:
This means you must wager the bonus amount, or sometimes the bonus plus your deposit, a certain number of times before any winnings can be withdrawn. Depending on the casino and promotion, wagering requirements can range anywhere from 15x to 50x or higher.
Capped bonus winnings:
Sometimes buried deep in the fine print is a maximum withdrawal limit attached to bonus winnings. For example, a casino may allow you to keep only the first $100 or $200 won from a no-deposit bonus. This can be a major drawback, particularly if you land a significant win while playing with bonus funds.
Promotion expiry dates:
Most online slots bonuses come with an expiry period. If you receive 50 free spins, for example, you may only have seven days to use them. Likewise, bonus funds often need to be wagered within a set timeframe before they are removed from your account.
Game restrictions:
Not every slot contributes equally towards bonus wagering requirements. Some games may contribute only a percentage of your bets, while others may be excluded from bonus play altogether. Certain casinos also restrict the use of Bonus Buy features while playing with promotional funds.
Online slots software companies
The World Gambling List puts player safety as our highest priority when recommending online casinos. We only endorse casinos that use licensed and reputable software providers. The company behind a slot often tells you a lot about the game, with some developers specialising in high-volatility slots and huge jackpots, while others focus on classic gameplay, innovative bonus features or themed releases. Here are some of the online slots software providers we endorse, but remember you should still be smart with your casino selection.

Pragmatic Play Online slots definitions
The types of slots games available on the internet are many and varied. There are progressives, video slots, 3D slots … and what the hell is a pokie? Here are some common types of slots.
- Classic slot machine: This type has three reels and is extremely simple in comparison to modern slots. Most online casinos will have a few classic slots available to real money players.
- Progressive slots: These slots have a jackpot which builds up as players put more money into it. Often the progressive jackpot will be linked to the software companies and every casino with the slot will contribute to the jackpot. The player triggers the jackpot, which can often reach into eight figures.
- Bonus slot: Often a video slot will have a bonus game waiting to be triggered. An exciting thing to look out for in coming years is slots developers adding games of skill to the bonus of their games.
- Pub slot: One of the original classic slots. You can find plenty of games such as Pub Fruity online.
- Multiple payline slot: A single payline slot means your winning symbols must line up on the one line. Multiple paylines means the winning symbols could be on different ‘lines’, even potentially in a zig-zag. Learn about the different paylines and ways-to-win in slots.
- Video slots: These are simply RNG games displayed on a computerized screen.
- 3D slots These are a reasonably new type of slot. They feature devastating graphics and, led by software providers such as BetSoft, have pushed slots into never-before-seen territory.
- Pokies: Australians and New Zealander like to call slots by the colloquial name of pokies.
- Penny slots: As the name advertises the machine accepts a minimum bet of $0.01.
- Community slot: A new type of slot that is beginning to take hold. Offers players the chance to interact during bonus rounds. These are often progressive slots. Games include Wheel of Fortune and a Powerball title.
If you hear someone refer to slots as a 243-ways or 1024-ways games it simply means that is how many chances you have of winning on the game if you are playing maximum lines.

Five reasons online slots are better
Online slots have got several advantages over land-based slot machines, including better graphics, bigger payouts and outstanding features.
Five reasons we think online slots are better than retail games include:
- House edge: This is such a big factor it even has its own section. We at the WGL play slots to win and the house edge is obviously a big factor in the bottom line.
- Graphics: While there have been a few cool slots at land-based venues over the years, online slots are far more visually pleasing, with obvious influences from the booming video-game industry. The advent of 3D slots has also made them more entertaining.
- Slots tournaments: What you might ask? But slots tournaments are a great way to win big from very little outlay. You won’t find slots tournaments at land-based casinos, with these pitting you against other players. The aim of the game is to get the most points and finish as high up a leaderboard as you can. Read more about online slots tournaments.
- Cheaper: It’s a broad statement that online slots are cheaper. But when was the last time you went to the pub and didn’t have a couple of pints and a meal with your slots playing time? You should get more bang for your buck by playing at home.
- Variety: We know of one online casino, Slots Million, that has more than 800 slot machines on the one website. You won’t find most of these titles at land-based venues and the themed slots available on the Web are outstanding.
- Aliens: Remember that mid-80s movie called Aliens? Well, NetEntertainment created an outstanding slot based on the classic cult horror film. You won’t find it at a bricks-and-mortar casino, but if you manage to find it online you are in for a good time.
House edge and online slots
We touched on how this works before. As a basic rule of thumb the more money you put into an online slot machine the less the house edge will be. For instance, playing a $1 slot and maximum lines could trim your house edge down to 3-4 per cent.
If you are playing a mid-priced game such as a 25-cent slot, the house edge is likely to be around 8 per cent at a land-based casino. Online you will be able to play 20-cent spins and still have a house edge of around 5 per cent.
Playing online you need to take into account whether the slot is a progressive game, which almost certainly will increase the house edge. The reason, of course, is that a few per cent of your initial outlay goes into a jackpot that can then go off at any moment.
So when playing online slots it pays to play maximum lines if you can afford it for a length of time. If you are playing a smaller denomination game you are probably better off using the “hit and run” tactic, meaning if you have an early win you should take the money and run because the house edge will eventually destroy you.

How to deposit at real money slots sites
Deposits at online casino vary greatly depending on where you are from. Tough gambling laws in countries such as the USA and China mean the options can be limited. But if you are from a country with more liberal gambling laws such as the United Kingdom or Australia, the options are endless. Some of the more common casino deposit options include:
- Cash deposits: This option is not for everyone because it’s not always possible. But it can work slots players in countries such as the UK, where online casinos have betting shops associated with them (think William Hill, Paddy Power etc). You can deposit at these land-based stores and the money will appear in your online betting account.
- Credit and Debit cards: This is by far the most popular deposit option for online slots players. Both credit and debit cards are instant and you can generally withdraw back to your Visa, although USA players may have to cash out with a check. Visa cards are the most common type of credit card accepted at slots sites. Read our guide to the best Visa casinos.
- Web wallets: These are used worldwide and can be a way for punters in countries where gambling is restricted to deposit money at online casinos. They are also a good option for bettors who don’t want to give out their card details or deal directly with the casino. Arguably the biggest and most popular web wallet is Paypal with many online slots sites having this deposit option.
- Bank transfers: This is generally facilitated between you and your bank. Often the slots site will have a bank account in your country, which means it will be an overnight transfer. If you are transferring internationally it can take up to three or four days to finalise a bank transfer to a casino.
- Pre-paid cards: More and more pre-paid cards are becoming available that act like a common Visa or MasterCard. Common prepaid cards include Ukash and American Express, while Visa have also forayed into the prepaid card zone, although there can be restrictions on these cards and depositing at gambling sites.

Online slots country guides
Online slots are accessible in almost any country in the world, although the legalities vary wildly, depending on your location. For instance, Australians are unable to play online slots (or pokies, as they call them) legally because of local laws which stamps out all forms of iGaming.
Other countries, like the United Kingdom and many states in the USA, have regulated online casinos and in-turn online slots, meaning residents here can play these real money games legally.
Below we will break down some of the key territories our readership is from.
UK online slots
Many of the top online casinos are based in the United Kingdom and it is perfectly legal to play real money slots at these gambling sites. The top UK online slots include many of the biggest brands in the world, including giants like bet365, William Hill and Leo Vegas.
United Kingdom online casinos are regulated by the Gambling Commission and if you are a slots developer, you must also seek licensing to operate here, which most the top dogs globally have done.
UK slots sites can be accessed via both desktop computer and mobile, with most gambling sites having downloadable apps for Android and iOS smartphones and tablets.
ZA online slots
South African allows online slots to be played at regulated gambling sites, with these rapidly expanding after increased iGaming regulation came into effect in 2022. The best online slots sites include brands like JackpotCity.co.za, which has launched a localised site, Betway and Hollywood Bets.
Many of the best online slots casinos have got apps for Android, iOS and Huawei smartphones and tablets, while they are also accessible via your web browser.
It is true that many online slots sites based overseas accept South Africans, but the World Gambling List chooses to only promote regulated brands.
