How Slots Work

How Online Slots Work

Unlike other casino games, such as blackjack and poker, playing slots online involves little skill. Luck alone determines whether or not you’ll hit a winning symbol combination when the reels stop spinning. Whichever symbols appear on the reals are determined by a random number generator (RNG), ensuring that the outcome of every spin is random and, as a result, fair. Under the Licensing Conditions and Codes of Practices set by the UK Gambling Commission (UKGC), every UK-licensed casino must use this technology on all games.

This RNG technology determines which symbol will show on each reel at the end of the spin. The outcome of every spin is separate from the previous and next spin, which means you’re never ‘due’ a win. Likewise, if a slot has just paid out the jackpot prize, there’s no saying it won’t pay out again on the next spin.

Certain online slots have an ‘autospin’ feature, which allows you to set your wager for a specified number of spins until you’ve spent the assigned credit.

How Online Slots Work

How to Play Online Slots

Slots are about as simple as it gets when it comes to online casino games – just set your bet, hit the spin button and wait to see if you get lucky. Even if you’re playing one of the latest video slots with multiple paylines and bonus features, the basic premise is the same. Sure, you might need to set your coin size and select the number of paylines you want to bet on, but that’s pretty straight forward too.

The more paylines you bet on, the more ground you cover. Just remember that your bet will multiply by the number of paylines you bet on, increasing your overall wager for that spin.

If you do land a combination of winning symbols, you’ll know about it. Music will play and images will appear on the screen to let you know that you’ve struck lucky. You’ll then have the option to use your winnings to play again or to keep them in your casino wallet.

Set your bet and select your paylines See if you land

Landed a win and want a fast withdrawal? E-wallets such as Skrill, Neteller and PayPal are often your best bet.

Our Criteria

How We Review Online Slots Sites

When we review online slots sites, we do so with slots players like you in mind. We take a look at everything from banking to bonuses to find the best slots sites to recommend to UK players. Here’s what’s on our hit list:


A current gambling licence from a reputable licensing body confirms that a slots site is a safe and fair place to play, and also that the site undergoes regular audits by third-party testing companies like eCOGRA. Here at, all our recommended slots sites for UK players are licensed by the UK Gambling Commission.

Welcome Bonus

Whether it’s a bundle of free spins, bonus funds or both, we love to see slots sites roll out the red carpet for new players with a great welcome offer. Our reviews take a deep dive into slot site sign-up deals to check which terms apply, highlighting restrictions such as wagering requirements and winning caps, and showing you where to find the best slots site offers.

Choice of Games

When we undertake slots site reviews, we always hit up the game tab to see what’s in store for players. The best slots sites complement a selection of many hundreds or thousands of real money online slots with classic table games like blackjack and roulette, and many offer live dealer games too.

Payment Methods

We think it’s important that slots sites offer a range of trusted payment methods, so our reviews always include a look at the cashier page. We expect to see options such as debit cards, Trustly and Paysafecard, as well as e-wallets like PayPal, Neteller and Skrill. Our reviews also cover deposit and withdrawal time frames, along with details of any fees.

Customer Support

Great customer support is a must for any business, and online slots sites are no exception. When we review new slots sites, we examine what’s available in terms of help for players. At the best slots sites, a comprehensive FAQs section is backed up by a variety of ways to get in touch with the team. This might include live chat, along with email and phone support.

Site Design

We spend time getting to grips with a slot site’s design and usability. We’re not interested in dreary sites that make it difficult to get to where you want to go. At, you’ll find fast-loading sites with fresh designs and straightforward navigation.

Mobile Compatibility

Playing slots on your mobile is great fun and also convenient, so we include detailed info about mobile compatibility in our slots sites reviews. Most sites have a mobile version of their main desktop site, but the best slots sites also offer native mobile apps. These apps come with perks like improved security and bonus code notifications, and are often available for Android and iOS mobile devices and tablets.

Slot Games

Slots You Can Play Online

Online slots might be simple, but there’s still plenty of variety when it comes to the games on offer. Whether you’re a fan of traditional fruit-machine style slot games, or prefer all-singing, all-dancing progressive jackpot slot games, the best online slot sites have something for everyone.

Classic Slots

These slots hearken back to the days of fruit machines, though the symbols aren’t necessarily fruit, bells and lucky 7s. Most classic slot games have three or five reels, making it pretty easy to select your paylines, which are almost always in one direction. This simplicity makes them a popular choice among slots newbies.

Mega Joker is one popular classic slot, with an appearance akin to a real fruit machine.

Video Slots

Video slots tend to have more going on that classic slot games. Expect crazy themes, tailor-made soundtracks and graphics that could give some video games a run for their money. These games offer players multiple ways to win, with some titles offering over 1,000 paylines in every direction you could imagine. Video slots also tend to have more bonus rounds and in-game free spins than classic slots. Video slots are perfect for players looking to combine their love of online casino with their favourite films, TV shows and music genres, with software developers such as NetEnt and Playtech partnering with big production companies to create branded video slots.

NetEnt’s Starburst is arguably the most popular video slot of all time, owing to its simple gameplay and inclusion in free spins offers.

Penny Slots

You don’t need to be a high roller to play online slot games, thanks to penny slots. You can bet as little as 1p per spin on these titles, which is great if you want to play real money slot games but have a limited budget. But that’s not to say that penny slots are a budget option, you’ll still get high-quality graphics, top-notch soundtracks and the chance to win big.

Progressive Jackpot Slots

This is where real slots enthusiasts get excited. Whereas most slot games have a fixed prize for winners, the prizes for progressive jackpot slot games just keep growing! However, even progressive games come in different shapes and sizes. Whereas some jackpots are specific to the online casino at which you’re playing, others are pooled between different casinos sites. Whatever the nature of the progressive jackpot, the size of the prize pool increases as players wager. These jackpots have been known to hit the hundreds of thousands, with titles such as Mega Moolah and Mega Fortune making players millionaires!

Mega Moolah regularly pays out jackpots into the millions of pounds to the luckiest players.

You may need to bet the maximum coin size to be in with a chance of hitting the top jackpot prize.

In our January 2021 interview with award-winning game studio Blueprint Gaming, Jo Purvis, Director of Marketing and Relationships, spoke to us about Blueprint’s Jackpot King progressive jackpot series and why the genre is so popular.

“There’s a large segment of players that absolutely love the possibility of winning huge amounts of money from any spin. For them, it enhances the gaming experience and adds something extra to the gameplay. Jackpot King is so successful because players have the opportunity of winning some amazing prizes, but they also get to play quality games at the same time. It simply makes for an entertaining experience, and those fortunate enough to reach the Wheel King are always on the edge of their seat in anticipation of what awaits.”


Features of Online Slots

Today’s slots players can forget about the nudge and hold features of traditional one-armed bandits. Modern online slots leave retro fruities in the dust with oodles of exciting features that make gameplay more thrilling and can boost your wins too. Let’s look at some of the common components of online slot machines.


Sitting vertically on the screen, spinning reels are the bedrock of online slot games, affecting both gameplay and the number of ways to win. Classic slots like Jackpot Jester and Couch Potato tend to have just three reels, while modern video slots such as Starburst and Book of Dead have five. For certain games, however, it’s the more the merrier where reels are concerned. The Raging Rhino slot, for example, has six reels, while Jammin’ Jars has eight.

Some developers also tinker with the mechanics of the reels, as well as the quantity, with avalanche reels being the perfect example. Also known as cascading or tumbling reels, this feature sees symbols that form part of a winning combination pay out before the symbols fall away, explode, or otherwise disappear from the payline. This allows new symbols to drop and, potentially, new winning combinations to form.


A payline is a line on a slot game which pays out if certain combinations of symbols appear. Traditional slots usually keep things simple with a single payline running from left to right. However, modern video slots have no such limitations, often featuring 5, 10, 20, 50 or 100 paylines which may run horizontally, vertically or in diagonal and zigzag patterns.

And that’s not the only way that paylines have evolved — games like Crazy Chameleon and Turning Totems have a Win Both Ways feature, which allows winning lines to form from left to right and from right to left. Meanwhile, Megaways slots, such as 88 Fortunes and Bonanza Megaways, use a reel modifier to alter how many symbols appear on the reels each round, creating many thousands of ways to win. In Cluster Pays slots like Astro Legends and Honey Rush, payouts are determined by the number of symbols that form clusters of five or more.


The latest slots feature a huge variety of themes, so you might find yourself matching anything from Irish leprechauns to Egyptian treasures. Many slot games also feature wilds and scatters. Acting as substitutes for other paying symbols to help you get a winning combo, wilds come in a range of styles, which do pretty much as their name suggests. Think sticky wilds, expanding wilds, walking wilds, multiplier wilds and more.

Wilds might be depicted as a simple logo, as a character of the game or as something else, but all serve to ramp up the chance of a payout. Scatter symbols work a little differently from wild symbols. Landing three or more scatters anywhere on the reels will typically trigger a bonus round where you’ll find even more goodies up for grabs.

Bonus Rounds

For many players, bonus rounds are the most exciting part of slot games, as it’s these games that increase your odds of landing a big win. Many bonus rounds are triggered by landing three scatter symbols, but this does vary, so remember to check what’s what in the paytable before you jump into real money play. Some games, such as Net Gains and Super Fruit Smash, include a feature that allows players to buy into a bonus round using cash.

You’ll find that the nature of bonus games varies between slots. Some games require you to pick from three or more things like lucky chests, wishing wells and golden eggs to win a bundle of free spins. Other bonus rounds offer multipliers that increase your final payout, and some slots will even give you a choice of bonus games.

Mobile Slots

Keep your Favourite Slots in Your Pocket

With so many players choosing their mobile for online gambling, slots developers create games with mobile players at the top of the priority list. This means there’s plenty of choice when it comes to mobile slot games. If the title has been built with HTML5, it’ll function identically across any device and operating system, whether you’re playing on desktop, mobile, or tablet. Furthermore, some of the best new slot games have been created especially for play on a smaller touch screen. Not only does this mean you can benefit from improved usability, but high-definition graphics too.

Every slot site on our list has a mobile-friendly website, but the best have developed native mobile casino apps for Android and iOS, which makes playing mobile slot games a breeze. Once you’ve downloaded the app, you’ll be able to sign into your casino account, ready to get from your home screen to your favourite title in just a couple of taps. As these apps are stored on the device, you’ll use less mobile data and won’t have to wait as long for pages to load. And if you’re looking to keep everything at your fingertips, pay by mobile slot sites could be a great option — you’ll only need your phone number to make a deposit.

We’ve picked out the top slot sites for playing on your mobile.
