What should you look for in the best online slots?


Return to Player percentage (RTP) is the amount a player can expect to receive back when playing an online slot game for an extended period of time, and is expressed as a percentage, e.g., a 96% RTP means that, on average, if a player wagers £10,000 on an online slot game, they have a reasonable expectation of getting around £9,600 back, barring major jackpot wins.

It needs to be borne in mind, however, that the RTP is a theoretical calculation, and that online slots operate with a random number generator (RNG) and so there is no guarantee that your actual returns will reflect the RTP. Online slot games are games of chance, and wins and losses do not necessarily conform to RTP expectations.

Nevertheless, on the whole the best online slot games to win have a higher RTP than the games you will find in bricks and mortar casinos and clubs, with most online games offering a RTP in excess of 95%, as compared to significantly lower rates of return in land-based slot games.

The exception to this is progressive jackpot slots, which have a lower RTP than most other online slots because a proportion of every losing spin on the game goes into the progressive jackpot pot, which is also why they can become so huge and grow so quickly.

The table below features the RTP of the some of the most popular and best online slots games:

Cleopatra (IGT)95.02%
Gonzo’s Quest (NetEnt)96%
Starburst (NetEnt)96.1%
Mega Moolah (Microgaming)88.12%
Book of Dead (Play n’GO)96.21%
Opal Fruits (Big Time Gaming)96.67%
Foxin’ Wins (NextGen Gaming)95.62%
Avalon (Microgaming)96.01%
Age of Gods (Playtech)94.03%

How to win at online slots

Just as there is a seemingly infinite variety of slot game themes to choose from, so is there a huge range of ways to win when you’re playing online slots.

You can still find some old-school 3-reel slots that only have 1, 3 or 5 paylines, but the number of these is relatively small compared to the range of 5 reel+ video slots that dominate the market.

5 reel slot games

Generally speaking, 5 reel slots will have anywhere between 10 and 100 paylines, and most games enable you to choose how many lines you have in play on each spin. However, it always advisable to bet the maximum number of paylines and reduce your coin size, rather than play a higher coin value on fewer lines, as having the full number of paylines in play not only increases your chances of hitting a winning spin, but in some games access to special bonus features or the biggest jackpots can be only gained when all the paylines are being played.

The combination of paylines and how they pay out will vary from game to game, so make sure you check these before you begin playing.

The way in which the reels and paylines are incorporated into the best online slot games to win is evolving all the time. Games like Starburst and Berry Berry Bonanza, for instance, have win-both-ways paylines i.e., they pay out both left-to-right and right-to-left.

Ways to win slots

Some of the best slot games have gotten rid of paylines altogether, and any 3 or more symbols on adjoining reels in any combination left to right is considered a winning spin. These games will usually have 5 reels, and feature either 3 rows (243 ways to win) or 4 rows of symbols (1024 ways to win).

Other games, such as the Megaways series of slots by WMS, have gone even further in coming up with innovative combinations of reels, rows and paylines. In Raging Rhino Megaways, for instance, the number of rows in play on each reel changes on every spin (from between 2 to 7), and combined with the fact that there are 6 full reels and an additional top row of symbols, there can be as many as 117,649 ways-to-win on any spin.

High v low volatility online slots

The volatility of an online slot game is generally determined by the frequency of the payouts and their relative size, and is in essence an expression of a game’s risk level.

Low volatility slots

A low volatility game is one where, when you play for any reasonable period of time, you can expect to pick up wins on a fairly regular basis, but these will tend to be small in relation to your line or total bet. You aren’t likely to land too many huge jackpot wins, but at the same time you probably won’t go through lengthy periods without any winning spins either.

On the other hand, when you play a high volatility online slot, there may well be fairly lengthy periods where you spin often but get little or no reward. However, the winning spins that you do hit will be proportionally larger and pay out a greater multiple of your bet.

High volatility slots

Whether you choose to play low or high volatility games will depend both on your approach to risk and the levels of engagement you want from your slots play. When you play high volatility slot games, you generally need a larger bankroll behind you to cover you for those times when you are spinning for little or no reward and your balance is shrinking quite quickly. The large payouts are likely to make this worthwhile in the long run, but you sometimes need both patience and resources to see out the lean spells.

If you’re the sort of player who always wants to be in the game and enjoy high levels of engagement through regular wins, regardless of their size, then it is more likely that for you the best online slot games to win will be low volatility games. The rate at which you use your bankroll will, on the whole, be slower, and you will get more action and payouts along the way.

In the end, it’s really just a matter of personal preference, and the option you choose will be an expression of what you hope to get out of your online gaming experience.

If you want to work out before you begin playing whether a slot is a high or low volatility game, then we would naturally recommend that you read our reviews first! If this isn’t possible, then the best way to work out a game’s volatility is to look at the payouts for hitting 5x symbols, either on a payline or as a scatter. The size of the win in relation to the line bet will be a good indicator as to the game’s volatility, as the higher the payout as a multiple of the bet, the greater the game’s volatility is likely to be (and vice-versa).

Slot bonuses and wagering requirements

The UK online casinos that we feature here all offer new players some form of welcome bonus as an incentive to register for an account. All such bonuses come with wagering requirements, which is the number of times you have to wager the bonus amount you are given before you can cash it out, or withdraw any winnings made from playing with bonus funds.

This means that the ultimate value of any bonus you receive will also in part be determined by the wagering requirement (also known as the playthrough), and so you need to consider both of these elements when weighing up a signup deal.

At most of the online casinos that we recommend here, slots games contribute to helping you clear the bonus 1:1, i.e., every £1 you wager on slots counts as £1 towards meeting the playthrough. However, it is always important to read the T&Cs, as at some sites there will be exceptions e.g., slot games that only contribute 50%-75% towards clearing the bonus.

You also need to check whether your wagers on progressive jackpot slots contribute to the wagering requirements — at some sites they do, at others they don’t, so if you play progressive jackpot slots regularly, make sure you know in advance whether this is helping you to meet the playthrough or not.

Tips for playing real money online slots 

Progressive jackpot slots

The gameplay on progressive jackpot slots is generally the same as you would find on any type of online slot, with one important difference — a proportion of every losing spin, wherever the game is played in the world, goes into the pot to create the progressive jackpot prize. This is why progressive jackpots are often worth tens of millions of pounds, and can grow to these enormous sums very quickly.

Most progressive jackpot slots will have a slightly lower RTP than non-networked games, although it will still generally be higher than you find on progressive jackpot slot networks at land-based casinos. This is because there are more versions of the game being played by more players around the clock in an online network.

While most progressive jackpot slots have engaging gameplay and are enjoyable to play in their own right (and most also come with some good base play payouts), there is no doubt that the reason most players opt to play them is the chance to win an enormous jackpot prize.

Strategies for playing progressive jackpot slots

Bearing this is mind, the key strategy when playing progressive jackpot slots is to ensure that you are betting the maximum number of coins and paylines. This is because on most games, you only have a chance to win the biggest jackpot when you are betting the max. However, most progressive jackpot games are accessible to the majority of players because they have a limited range of coin sizes, so you can usually play the game regardless of the size of your bankroll.

There is a trade-off when you play progressive jackpot slots, in that the RTP is lower than on other games, but the potential payouts more than compensate for this, making them unequivocally the best online slots games to win.

Ultimately, it depends on your approach to risk and what you want from your online gaming experience. If you want the chance of hitting a life-changing win, then you will likely consider playing progressive jackpot slots to be worthwhile, particularly as the wager sizes are no greater than other games. This is even more so the case when you consider that the payouts from games like Mega Moolah (Microgaming) and Mega Fortune (NetEnt) are potentially worth tens of millions of pounds.

Play slots with a high RTP

If you want to get value from your online slots play, then it is worth your while exploring the RTP of different games. It varies from game to game, but you can generally expect the best online slots to have a RTP in excess of 95% (with the exception of progressive jackpot slots).

Our online slot game reviews will generally include a game’s RTP, while many of the UK casinos that we feature here will list the RTP of its games on their site.

Free spins and no deposit bonuses

Many of the online casinos that we feature here offer new players welcome bonuses where you can pick up no deposit bonus spins, or free spins in conjunction with a deposit match bonus. With a no deposit bonus, you can usually expect to get between 5 to 20 spins, while when you pick up free spins along with a deposit match, you will usually get between 100 to 500 spins as part of the deal.

In most cases, these bonus spins will be on a specific game (or games). Taking advantage of these spins gives you the chance to check out games without dipping into your bankroll, so you can explore slot titles that you may not have had the chance to play previously. This is one of the best ways in which to find new slots with gameplay and themes that you enjoy, and to check out all the special features and bonus rounds they have.

Take advantage of signup bonuses and low playthrough requirements

One of the biggest changes in online gaming has been brought about by the introduction of HTML5 technology, which has meant that more and more UK online casinos are now able to offer the games of a variety of different developers alongside each other. This has been a hugely positive development for players, as you get great gaming choice and variety, along with a larger range of titles at the best UK casino sites.

This also means that you will be be able to find many of the same slots titles on offer at a variety of different casinos. It therefore makes good sense to look around at the various sites that feature your favourite slot games and compare the value offered by their respective signup deals. In this way, you are not only getting to play the best slot games, but are also getting the best possible value while doing so.

Local v network progressive jackpots — which is best?

Most progressive jackpot slots are part of a large network operated by the game’s developer. This means that the jackpot prize of a game like Mega Moolah is made up from a proportion of every losing spin at every online casino where the game is being played, no matter where it is in the world. With thousands of players playing the game at any one time, the prize pool grows bigger every minute of every day, and so the jackpots in these games can quickly reach enormous sums.

There are, however, some progressive jackpot slots that are played via local networks. In this scenario, the prize pool will grow from the losing spins on the game only at one particular online casino, or perhaps a small group of casinos being run by the same operator. This means that the jackpot prize will not grow as quickly as in networked games, and will generally not reach the same sort of size. However, at the same time there is the advantage that there are not as many players competing at any one time for the top payout.

Special features on the best online slot games

In the best online slots games to win, the most lucrative payouts are won via the special features, such as free spin rounds, multipliers, scatter and wild symbols. These payouts are usually well above the size of the wins you can pick up in base play, and so it pays to have a good understanding of how these function in any online slot game you play.

This is why it’s important to check out a game’s paytable in order to know which symbols are the most valuable, what features the scatter symbols trigger, the rewards the wild symbols give you, and how the free spin bonus rounds operate. In this way, you are more engaged in the game as you know what is happening at all times, as well as where the biggest payouts can be won. 

Types of slot games

Slot games have come a long way since the first versions appeared, and developments in technology have undoubtedly taken online slots gameplay to new levels of sophistication. 

Below are examples of some of the types of gameplay you can enjoy on the best online slots.

Flux slotFlux

This 5-reel slot game by Thunderkick is notable for its free spin bonus round, which gives you a choice as to how you take advantage of the bonus; you can opt to have wins pay both ways, get extra rows of symbols on the reels, or simply take more free spins with the reels set up as in base play.


Opal Fruits Slot Online ReviewOpal Fruits

Big Time Gaming’s Opal Fruits combines traditional slot machine fruit symbols with ultra-modern gameplay. The game features 6 reels with 3 rows, plus additional 4 reel rows at the top and bottom of the main reels which spin horizontally rather than vertically, producing up to 5,625 ways to win. It has also has the Reactions feature, where symbols in a winning spin disappear from the reels and are replaced, meaning multiple wins are possible from a single spin.

Thunderstruck II SlotThunderstruck II

One of the most popular and successful online slots games of all time, Microgaming’s Thunderstruck II introduced the concept of a progressive free spins feature. Every time you trigger the Chamber of Spins round, you make your way through the five different levels of bonus round, with the gameplay and rewards changing at each tier. What is unique about this feature is that the bonus level you attain carries over from one gaming session to the next.

Planet of the ApesPlanet of the Apes

This unique NetEnt slot is a 10 reel 40 payline game that in reality consists of two 5 reel 20 payline games that are separate yet connected. There are two distinct play areas — Rise and Dawn — each with its own discrete symbols and paytable, although all 10 reels are in play on each spin. The game is packed with special features that create quite sophisticated and complex gameplay, and this is backed up by outstanding production values that will make this one of the best slot games you are ever likely to play.

Aloha Cluster Reels Online SlotAloha! Cluster Pays

Rather than traditional paylines, NetEnt’s Aloha! is a 6 reel games that has the unique cluster pays feature, where 9 or more symbols appearing adjacent to each other, either horizontally or vertically, creates a winning combination. There is also a sticky win re-spin feature, where symbols are held in place during the re-spin, with any further symbols that are added to the winning cluster increasing the size of the payout.

Starburst Online SlotStarburst

A hugely innovative game that remains as popular today as when it was first released in 2012, NetEnt’s Starburst was one of the first games to have the win-both-ways feature, where wins are paid out for hitting 3x or more symbols on a payline both left-to-right and right-to-left. It was also one of the first games to feature sticky wilds, where a wild symbol expands to take up the entire reel, and then stays in place for an additional free spin, increasing the potential payout size. Starburst is also notable for the eye-catching beauty and simplicity of its design. 

Slot game bonuses

The best slot games have bonus features that give you payouts beyond those you get during base play. Often, these will be for hitting wild symbols or scatter symbols, and can trigger special bonus rounds as well. Free spin rounds and bonus games are generally where the biggest wins are, and during these sorts of features multipliers are often applied to winning spins so that the size of the payouts is further increased.

In addition to these sorts of in-game bonuses, the UK online casinos that we feature here also provide a range of welcome bonuses for new players, as well as ongoing rewards for regular players that give you extra value and additional bonuses once you’ve signed up for an account.

Free spin bonuses

Welcome Bonus free spins for new players will either come in the form of a no deposit bonus, or as part of a deposit match bonus. With the former, you can expect to receive in the region of 5 to 20 spins on a selected slot game, while with a deposit match bonus you will get anywhere between 50 to 500 free spins, usually on a designated game (or games). 

It is always important to remember, however, that any winnings from a welcome bonus (including winnings from free spins) will be subject to wagering requirements. This is the amount you have to wager before you can cash out any bonus winnings, and is expressed as a multiple, e.g., 30x, 40x, etc. This means that if you take advantage of a signup deal that gives you a £100 bonus with a 40x wagering requirement, you will need to wager £4,000 in total before you can cash out.

With most free spin offers, you will also find that winnings are capped (usually somewhere between £100 and £200), and that a playthrough requirement is applied before these winnings can be withdrawn, e.g., if you win £200 and the wagering requirement is 30x, you would have to wager £6,000 in total before you can cash out those winnings.

Ongoing bonuses for regular players

However, bonuses aren’t just for new players, and once you have signed up at an online casino you can still continue to pick them up. A lot of sites offer players re-load bonuses, for instance, where when you make a deposit during a promotion period, you get a match bonus, or you might be offered free spins as well. VIPs often receive match bonuses or free spins when they make deposits during exclusive promotions, or you might be given the chance to pick up some free spins when a new slot game is released.

However, as is the case with signup deals, you can expect that most of these sorts of bonuses will also come with wagering requirements.

The best online slot game developers

New slot game producers are entering the market all the time, meaning that players have more choice and variety as the type of games they play than ever before. Below are some of the leading game developers who produce the best online slot games at our recommended UK online casinos.

Netent SoftwareNetEnt

NetEnt has successfully established itself amongst the top echelon of online slots producers through its innovative approach to gameplay and the advances in graphics and design it has introduced. Themed slots, as well as slots with their own original themes, are hallmarks of the NetEnt slot catalogue, and its progressive jackpot network has also grown significantly, with Mega Fortune in particular regularly paying out spectacular jackpot wins. NetEnt has also branched out into live dealer games, and these have proven to be very popular at UK online casinos as well. Many of the best slot games to win at our featured sites are by NetEnt, including Starburst, Gonzo’s Quest, Guns N’ Roses, Jack Hammer (1 & 2), and Jack and the Beanstalk. 

Microgaming SoftwareMicrogaming

Microgaming has been one of the leading names in the online gaming industry for more than two decades, and has been behind some of the biggest and most important innovations in online slots. Microgaming produces games in all categories, with its progressive jackpot slots perhaps being the type of game it is best known for, although many of the most popular video and themed slots are also products of the Microgaming studio. Some of the best-known Microgaming slots include Game of Thrones, Jurassic Park, Avalon (1 & 2), Thunderstruck (1 & 2), and Immortal Romance. Mega Moolah, Microgaming’s flagship progressive jackpot slot, is also rightly famous and continues regularly to award jackpot wins that are worth tens of millions of pounds.

Blueprint Gaming SoftwareBlueprint Gaming

UK-based Blueprint Gaming was founded in 2007 and it develops games under its own label as well as for other brands, with its slots being found in a growing number of well-known online casinos. Visually creative and featuring imaginative gameplay, Blueprint Gaming slots include a range of Megaways games and themed video slots, with some of its most popular titles including Mars Attacks!, Ted, Top Cat, Worms Reloaded and Winstar.

Barcrest SoftwareBarcrest 

Operating as a subsidiary of Scientific Games, Barcrest produces both land-based casino slots as well as online games, and has more than 50 years’ experience in the gaming industry. Some its most popular cabinet slots have been translated into online versions, and it also produces a growing range of original games designed specifically for online and mobile platforms. Rainbow Riches is probably Barcrest’s best-known and most successful title, with other games in its catalogue including Monopoly Big Event, Ooh Aah Dracula, Wild Times and Thai Flower.

ELK Studios SoftwareELK Studios

Swedish game developer ELK Studios launched in 2013 and is notable for its eclectic range of games that encompass a broad range of themes and include a number of innovative gaming features. Its slot games can be played at a growing number of our featured UK online casinos, and it has a focus on producing high quality games designed specifically for mobile gaming platforms. The ever-growing range of ELK Studios slots includes well-known titles such as Taco Brothers, Ho Ho Tower, DJ Wild, Poltava and Wild Toro.

NYX Gaming SoftwareNYX Gaming

Based in Las Vegas and now part of Scientific Gaming, NYX Gaming produces a large range of around 650 online games, including slots, bingo and lottery games. NYX’s slots are developed for both HTML5 and Flash platforms, and its range includes a good mix of styles and themes, with its superhero slots being some of the most popular titles in its catalogue. Well-known slots produced by NYX Gaming that you can play at our featured UK slots sites include Foxin’ Wins, Justice League, Cherry Blossoms and Mad Mad Monkey.

IGT SoftwareIGT Software

IGT is unusual amongst online slot developers in that it also has a presence in the land-based casino industry as well, in addition to social gaming and running state lotteries. It has a growing catalogue of online slots games, including an increasingly popular progressive jackpot slot network, and so you’ll find its games at many of our recommended UK online casinos. Well-known IGT slots titles include Wolf Run, Kitty Glitter, Family Guy and Da Vinci Diamonds, while the Mega Jackpots progressive network includes games such as Cleopatra, Siberian Storm and Golden Goddess.

Playtech SoftwarePlaytech

One of the ‘Big 3’ producers (along with NetEnt and Microgaming), Playtech has been in the online gaming industry for 20 years and in that time has established a strong reputation not only for producing online slots, but also bingo, poker, live dealer games, sports betting software and social gaming platforms. Several smaller producers also operate as part of Playtech, and so it has a significant presence in the online casino and gaming world. Its range of online slots include several different progressive jackpot networks, as well as some well-known stand-alone progressive slots, with popular titles in the Playtech catalogue including The Sopranos, Gladiator, Kong: 8th Wonder of the World and Azteca.


Quickspin began operating in Sweden in 2011 and its growth and success was so rapid that it was acquired by Playtech in 2016, although it still continues to produce games under its own label. The company has had significant recognition by the online gaming industry, winning numerous awards, and it supplies games not only to leading UK online casino sites, but has also branched out into land-based games as well. Quickspin games are notable for their original themes and narratives (it doesn’t produce branded slots, for instance) and these quirky slots are increasingly popular with players around the world. Some of the well-known Quickspin slots you can play at our featured online casinos include Sakura Fortune, Mayana, Mighty Arthur, Rapunzel’s Tower and The Epic Journey.

Realistic GamesRealistic Games

A UK-based game developer that has been operating since 2002, Realistic Games was a pioneer in the devolvement of HTML5 slots for online and mobile platforms, and it now has a significant portfolio of games that you can play at a range of leading UK online casinos. With a number of industry awards under its belt, the company has continued to grow, and it has recently signed an agreement to supply its games to operators using the Microgaming integrated platform. Realistic Games slots are noted for their high quality graphics and fun themes, with some of its most popular titles including Sunset Reels, Fortune 5, Black Ice and Symmetry.

WMS Software CasinoWilliams Interactive

More commonly known as WMS, Williams Interactive is now part of the Scientific Games group, but it started out more than 50 years ago producing pinball machines, arcade games and juke boxes, eventually moving into cabinet slots and then finally online slot games. It has a large portfolio of games, although it tends to specialise in slots with historical and mythical themes that have a broad appeal, and its games can be played at most of the leading online casinos that we feature here. Popular WMS slots include Raging Rhino Megaways, Spartacus Call to Arms, Great Zeus and Viking Vanguard.

Yggdrasil SoftwareYggdrasil

Since its launch in 2013, Scandinavian game producer Yggdrasil has made a big impact through its slots which are notable for their innovative themes and engaging gameplay. Yggdrasil slots are beginning to appear at a growing number of our featured online slot sites, and their high production values have led to the company winning a number of industry awards. Some of the best-known and most popular Yggdrasil online slots games include Lucha Maniacs, Easter Island, Gem Rocks and Ozwin’s Jackpots.

Playing online slots v other casino games

Undoubtedly one of the reasons that online slots are so popular is because they are very accessible and can be enjoyed by anyone. Unlike many card games and table games, you don’t need to know complicated rules, or master some obscure vocabulary to be able to play and enjoy the best online slot games. Even in slots with the most sophisticated gameplay, the way in which the game is operated is relatively straightforward, and no complex wagering or playing strategies are required.

Varieties of slots games

This means that slots have widespread appeal, and can also cater to a wide range of tastes. For instance, you can enjoy classic, old-school 3-reel slots, where the gameplay is at its most simple, as well as more elaborate games with a huge variety of paylines and packed with special features and bonus rounds. This ability to cover all of the bases when it comes to playing styles is one of the major reasons for slot games’ ever-growing popularity, as they have something for everyone.

Although classic casino table games do have some variations — for instance, you can play single or multi hand blackjack, or American, French or European roulette — these games don’t offer anywhere near the sort of variety that the best slot games do. No matter what your interests are, you will be able to find an online slot game with a theme to match — from mythology and fantasy, to ancient history, to the latest hit TV shows, movies and video games, you will be able to play a slot game that is designed to cover your interests.

Slots jackpots

The best online slot games to win also have huge jackpot wins that other sorts of casino games can’t match. Progressive jackpot slots regularly create multi-millionaires, and just about every game gives you the chance to win sizeable payouts. In contrast, when you play blackjack or roulette, your wins are much more limited in comparison, no matter how good a player you are.

Some players prefer casino table games or video poker as these have a lower House edge (i.e., a higher RTP) than most online slots, but this is because you can’t win a huge jackpot payout on the turn of a single card in the same way that you can with one spin on an online slot.

And in the end, this is their great appeal. Online slots may ultimately be high risk games, but they also offer the potential for very big rewards.
