Best Slot Games to Play in 2026
If you compare the best slot games list from 10 years ago to the current list below, you’ll notice that both feature a game provider that dominates with several titles.
The once-mighty NetEnt was a powerhouse that, from 2010-2015, churned out hit after hit with ground-breaking slots such as Gonzo’s Quest, Twin Spin and Dead or Alive.
Then, around 2016, a young upstart studio called Pragmatic Play came along. While it was true to say that some of their earliest releases were nothing to write home about, they soon found their groove - and the rest is history.
Commanding an incredible 9 positions in the top 20 best slot games to play at slot sites in the UK, Pragmatic Play have firmly established their position as players’ #1 game provider.
1. Big Bass Splash (Pragmatic Play)
Hot off the heels of Big Bass Bonanza’s success comes Big Bass Splash which follows the familiar format, but with a number of significant upgrades.
First off, the theme is given a little makeover with the bearded fisherman now taking on a redneck persona. Driving a monster truck, our redneck fisherman opts for a less eloquent method of catching fish by firing launching dynamite to blow them out of the water
The updated game is given some radical features including the random Bazooka feature plus a respin opportunity to hook a 3rd Scatter when only two drop.
Once the feature bonus is triggered by landing 3 Scatter symbols, you’ll be given the chance to net yourself additional features including More Fish, More Fishermen, +2 Free Spins, Start at Level 2 and More Dynamite, Hooks and Bazookas.
2. Gold Blitz Express (Games Global)
Gold Blitz Express delivers fast-paced action with a glittering golden edge. It follows a classic fruit slot format enhanced with a Hold & Win mechanic.
The layout combines traditional fruit symbols with modern cash prize icons. Land 6 or more Cash symbols to activate the bonus round.
In the Hold & Win feature, all cash symbols remain locked while respins continue. Filling the grid or landing jackpot symbols awards fixed prize amounts. This is not a fixed paylines slot, with over 4,096 possible combinations.
Players can claim a maximum win of up to 1,999x their stake, with bets ranging from £0.20 to £150.00 a spin.
3. Big Bass Bonanza (Pragmatic Play)
Proving that you can take any subject and create a successful slot by applying a little genius, Big Bass Bonanza became the launching pad for an extremely successful series of ‘Big Bass’ slots based around fishing.
Technically, Reel Time Gaming’s Fishin’ Frenzy was the first such slot, having taken up residence on casino gaming floors around the world some years prior.
The feature bonus is where the ‘reel’ fun starts - land 3, 4 or 5 Scatter symbols to receive 10, 15 or 20 free spins respectively. During the free spins, you’ll bank any cash prizes that land if accompanied by the fisherman collector symbol.
The free spins bonus also offers a trail through which you progress with each Fisherman Wild symbol that lands. Every 4 steps awards a retrigger of 10 more free spins with an increased multiplier of up to 10x.
4. Big Bass Vegas Double Down Deluxe (Pragmatic Play)
Big Bass Vegas Double Down Deluxe follows the familiar Big Bass collection format, with a Las Vegas theme and added bonus features.
The slot uses a 5x3 layout with fixed paylines and includes fish symbols displaying cash values, alongside card ranks and premium themed icons. Base game wins pay from left to right, while Scatter symbols act as the entry point to the bonus round.
Landing 3 or more Scatter symbols triggers the Free Spins feature.
During free spins, fisherman Wild symbols collect all visible fish values on the reels and award them as a combined payout. As additional fisherman symbols land throughout the feature, progressive multipliers increase in stages, and extra free spins can be awarded.
5. Double Bubble (Roxor Gaming)
Double Bubble is a straightforward fruit-themed slot with a traditional structure. Picture a bright, candy-coloured backdrop where playful bubbles pop in bursts of sweet excitement.
It uses a classic 5-reel layout with 20 paylines and familiar symbols such as cherries, lemons and sevens.
The game focuses on simple line wins rather than complex bonus rounds. It is a high-volatility slot with an RTP of 96.02%.
Multiplier elements may apply to certain winning combinations, keeping the gameplay easy to follow and fast-paced.
Double Bubble can give players the chance to win up to 22,000x their stake, with their Bubble Line boost symbol.
6. Book of Dead (Play’n GO)
Play’n GO created this modern-day classic nearly a decade ago, and since then, it’s been the inspiration for hundreds of similar ‘Book of’ slots.
That’s mostly down to the extremely popular Expanding Symbol mechanic, which is randomly selected during the free spins bonus.
To trigger the bonus and receive 10 free spins, you need to land at least 3 Tomb Scatters. The Book is revealed, and a random Expanding Symbol is selected. The premium symbols pay more, but are less likely to hit, while the lower ones hit more frequently, but pay less.
Rich Wilde, the leading character, is ‘devilishly handsome with an innate sense of adventure’ according to Play’n GO.
In fact, he’s so adventurous that you’ll find a whole series of Rich Wilde slots of a similar theme, including Rich Wild and the Amulet of Dead, Rich Wild and the Shield of Athena and Rich Wilde and the Tome of Insanity, to name just a few.
7. Eye of Horus (Blueprint Gaming)
Eyes of Horus by Blueprint Gaming is a medium volatility, 5x3 slot built around expanding symbol free spins.
The game uses 5 reels, 3 rows and 10 fixed paylines, so it is fairly easy to navigate, even for slot novices. It is an Egyptian theme, with traditional card values and themed premium symbols.
Three Eye of Horus Scatters trigger the Free Spins feature. During free spins, one symbol is chosen to expand fully on any reel it lands on, increasing the chance of forming multiple winning paylines. 500x your bet is the maximum payout.
8. Starburst (NetEnt)
What can be said about the most iconic online slot of all time that hasn’t been said before? NetEnt’s Starburst is where many online slot players first cut their teeth.
Most of the best UK casino sites award free spins on Starburst as part of their welcome bonus offers. This all-time classic is simple, yet engaging with mesmerising graphics, animation and ethereal sound effects.
There is no complicated bonus round - the Starburst Wild symbol is present on reels 2, 3 and 4. When it lands, it expands to cover the entire reel and awards a respin. Landing an additional Starburst Wild awards another respin, but now you have two expanded Starburst Wilds which is where the big wins can occur.
The reel symbols consist mainly of precious gems, but it’s the Red 7s and Gold Bar which top the pay table. With 10 fixed paylines paying both ways, it’s not hard to see how Starburst has remained in the Top 10 for over a decade.
9. Big Bass Splash 1000 (Pragmatic Play)
Big Bass Splash 1000 follows the popular Big Bass format with added multiplier potential.
Fish symbols carry cash values, while the fisherman acts as a collecting Wild during bonus rounds. Landing 3 or more Scatter symbols activates Free Spins.
Throughout the feature, collected fish values are added together and progressive multipliers can increase winnings as more fisherman symbols land.
Bet stakes range from £0.10 to £500.00 per spins, with the maximum win being 25,000x your stake.
10. Fluffy Favourites (Eyecon)
Although not personally fond of this classic slot from Eyecon, the numbers don’t lie.
The artwork, sound effects and bonus round are as basic as you can get - even by 2016 standards. But it’s probably this simplicity that gives it the charm that appeals to many slot players.
Reel symbols consist of cuddly toy-type characters, particularly those that you’ll find in the claw machines found at the fair. Which is exactly why the Claw Scatter symbols trigger the Toybox Pick bonus where you’ll receive up to 5 grabs at claiming a prize.
Each successful pick reveals a random bet multiplier of up to 100x your bet. Up to 25 free games can be awarded when landing the pink elephant Wild symbol, which also doubles any win.
11. 333 Boom Banks 2 Power Combo (Games Global)
333 Boom Banks 2 Power Combo builds on the original with an expanded respin and multiplier format.
The game uses a 5-reel layout and features fruit and classic slot symbols alongside special cash and multiplier icons. Wins are formed through standard paylines, with coin symbols acting as the gateway to the bonus.
The main mechanic revolves around the Boom Banks respin feature. Landing 6 or more coin symbols triggers the bonus, where all coins lock in place and respins are awarded.
Special Power Combo symbols can add extra respins, apply multipliers to coin values or unlock additional positions on the reels, while fixed jackpot prizes are available if specific combinations are completed before the respins run out.
12. 9 Pots of Gold (Gameburger Studios)
Surprisingly, for such a popular genre, 9 Pots of Gold is only one of two Irish-themed slots in our list, of which both are from Gameburger Studios.
With reel symbols featuring Leprechauns, harps, 4-leaf clovers and pots ‘o gold at the end of the rainbow, this wonderfully crafted slot manages to blend everything considered ‘Lucky Irish’ into one game
Landing 3 or more Pot Scatters on any reels awards a climb of the ladder and a cash prize of up to 2,000x your stake.
The Free Spin Wheel is awarded when you land 3 or more Free Spin symbols. Each wedge on the Free Spin Wheel contains a number of free spins plus a multiplier, with up to 30 free spins and a 3x multiplier available.
13. Big Bass Floats My Boat (Pragmatic Play)
Big Bass Floats My Boat continues the Big Bass collection format with added features and higher multiplier potential.
The slot follows a 5x3 layout and includes fish symbols carrying cash values, alongside tackle-themed premium symbols and standard card ranks. Base game wins are paid left to right across fixed paylines.
Three or more Scatter symbols activate the Free Spins feature.
During the bonus round, fisherman Wild symbols collect all visible fish values on the reels and add them together for a single payout.
As more fisherman symbols land across the feature, progressive multipliers can increase in stages, allowing later spins to carry significantly higher win potential.
14. Fourfold the Gold (Games Global)
Fourfold the Gold is a classic 3 row, 5 reel and 25 paylines fruit slot, with an added multiplier focus. It sparkles with classic Vegas glamour and golden ambition.
The layout features traditional symbols such as fruits, bells and gold bars. The key mechanic revolves around multiplier symbols with the beer barrel being the highest paying base symbol and card suit symbols being the lowest payout symbol.
When multipliers land on winning combinations, they can significantly increase payouts, in some cases multiplying wins up to four times.
15. Legacy of Dead (Play’n GO)
The sands of ancient Egypt whisper secrets untold, and Legacy of Dead from Play’n GO captures that mystique flawlessly.
Legacy of Dead is a 5x3, high volatility slot built around an expanding symbol free spins mechanic.
The theme centres on ancient Egypt, with explorer Rich Wilde joined by traditional low and high-value symbols.
The Book symbol acts as both Wild and Scatter. Land 3 or more Book symbols to trigger 10 Free Spins. At the start of the feature, one regular symbol is randomly selected to become the expanding symbol, potentially covering entire reels and creating strong payout opportunities. The max win is up to 5,000x your stake!
16. Gold Blitz Ultimate (Games Global)
Gold Blitz Ultimate bursts onto the scene with high-voltage energy and instant-cash thrills.
This is a cash-collect style slot focused on Hold & Win gameplay. The reels feature classic fruit symbols alongside cash value icons and jackpot symbols. The core feature is triggered by landing 6 or more Cash symbols.
During the Hold & Win bonus, cash symbols lock in place while respins are awarded. Landing additional cash symbols resets the respin counter, with Mini, Major and Mega jackpots available.
Players can bet between £0.20 and £0.50.00 per spin, and with multipliers of up to 10x, you can have a maximum win of up to 5000x your bet.
17. Age of the Gods (Playtech)
Age of the Gods by Playtech is a mythology-themed slot linked to a progressive jackpot network. This slot invites you to ascend Mount Olympus and stand among legends.
The reels feature classic standard card symbols, as well as Greek god symbols, each of which has different rewards. For example, the Athena bonus grants random multipliers between 2-5x before free spins, and the Poseidon bonus, which, with a strike of lightning, can turn 5 symbols into wilds.
Scatter symbols trigger Free Spins, depending on the specific Age of the Gods title variant.
The game is primarily known for its four fixed progressive jackpots, Mini, Minor, Major and Mega, which can be won randomly during gameplay.
18. Buffalo Blitz (Playtech)
Buffalo Blitz is a 4-row, 6-reel slot centred around a Hold & Win style bonus with 4096 paylines.
The theme includes wildlife symbols alongside cash prize icons. All coins have different values attached to them, with the Buffalo coin being the highest at 300x coin value and the 10/9 being the lowest with a 100x coin value.
Landing enough coin or cash symbols triggers the respin feature.
During the bonus, symbols lock in place and respins continue until no new symbols land, with fixed jackpots available for completion patterns.
19. 12 Pots of Gold Drums (Games Global)
12 Pots of Gold Drums combines a traditional Irish theme with a hold-and-respin style bonus mechanic.
The slot is played on a 5x3 layout with fixed paylines and features leprechauns, harps and pots of gold alongside standard card symbols. Wins pay from left to right, while gold coin symbols are central to unlocking the main feature.
The primary mechanic is the Pots of Gold respin bonus.
Landing 6 or more coin symbols triggers the feature, where coins lock in place and respins are awarded. Each additional coin resets the respin counter, and the aim is to fill positions on the reels to unlock fixed jackpot prizes before the respins expire.
20. Big Bass Amazon Xtreme (Pragmatic Play)
Big Bass Amazon Xtreme brings all the best elements of the Big Bass series of slots, but this time it receives an Amazonian makeover.
The bearded fisherman sits snoozing in his canoe, waiting on a big catch that appears in a randomly thrown net, where he’ll leap into action. Other random features include a Waterfall that adds additional fish during the Free Spins.
The Free Spins feature starts with the opportunity to take a pick from 13 clay pots - each one adding a free spin modifier such as more fish, more fisherman or guaranteed fish.
Big Bass Amazon Xtreme maintains the bonus trail, which is climbed by landing the Fisherman Wilds. Each level achieved awards more free spins, and true to the Xtreme title, up to 70 extra free spins are available along with a massive 50x multiplier.

How We Review The Best Slots Games
As slot experts at Gambling.com, we review new slot games every week. We have years of experience having played the best online slot games in the UK. Although every slot provides an entirely different gameplay experience, we put each game through a rigorous review process that allows us to bring you objective conclusions. We also add to our reviews the subjective opinions of our experts and their likes and dislikes of each casino slot.
How Slot Games Work Online
Understanding the features, game mechanics and logic of online slot machines will help you create your own slot strategy and better prepare for success when spinning those digital reels. Read our Gambling.com guide further to better understand the ins and outs of online slot machines, and for a hands-on learning experience check free slots reviews and try them out. Don't miss our list of the highest paying casinos, which also features the top 15 highest paying slots.
Online Slots RNG
Similar to land-based casinos, online slot machines have a Random Number Generator (RNG) which makes sure that the symbols on the reels land in random positions with every spin. All the casinos we recommend on Gambling.com are licensed by the UK Gambling Commission (UKGC), which requires the RNG to be certified and tested regularly. So you can be sure that no casino slot we feature on our site is rigged and the symbols always land in a random order.
What are Paylines?
Being one of the core elements of any slot machine, paylines mark the all the possible winning symbol combinations. The number of paylines on a casino slot will determine how many ways you can win while spinning the reels. You can choose how many lines you wish to play and in which combinations, as well as decide how much money to bet on each line.
How Many Reels and Paylines Do Online Slots Have?
The most basic slot games usually have 3 reels and a single payline that typically goes through the centre of the reels. However, technology has come a long way and today’s game designers offer online video slots that feature 5, 7 or 9 reels and hundreds of paylines. Some UK slot games feature 243 ways to win, while there are even slots with 1024 possible winning combinations.
5-reel slot games have become the standard for many online slots, while a game can offer anywhere between one to hundreds of paylines. The innovation and creativity of online slot designers recently brought slots with 1024 ways to win where, instead of traditional paylines, wins are given for any left or right-aligned symbol combination that lands on the reels.
How Much Can You Bet On an Online Slot Game?
The amount you can bet on a slot game will depend on its min/max bet limits, number of paylines and other game rules. You must bet at least the minimum and check the paytable to understand how winning combinations occur. In standard slot games, the winning combinations read from left to right, but there are many new and innovative slots that award wins for symbols clustered or grouped in multiple directions.
Every wager you make will deduct coins from your balance. For every payline you select, you will need to make an extra bet. The minimum bet is 1 coin, so if you would like to bet on a slot with 25 paylines for example, you will need to bet a minimum of 25 coins. The values of coins changes from one slot game to another. While some slots allow you to place a few pence per bet, others will require £1 per for each wager.
Mobile Slot Games
With most slot players preferring to spin the reels on mobile, the majority of online slots are coded in HTML5, optimising them for mobile devices. Most developers use a mobile-first approach, ensuring new releases are designed for immersive mobile casino gameplay. Even classic online slots have been updated for mobile play, with most available instantly via mobile casino browsers or apps on Android, iOS and Windows Phone.
Slot Games RTP (Return to Player)
When you place a bet on a slot machine, it's natural to wonder how much you could potentially win. While slot payouts are random, each game's expected return is calculated through a precise mathematical model known as RTP, or Return to Player.
Understanding RTP
RTP is a percentage that shows how much money is returned to players over time. For example, if a slot has an RTP of 96%, it pays out £96 for every £100 wagered by all players collectively. However, since wins are random, one player might lose £100 while another hits the jackpot with just a few pounds.
Free Slot Games Online
Many websites let you play the best casino slots in demo mode, allowing you to try them out for free without spending your own money. This is a perfect way to explore different slots, getting a feel for the game’s theme, design, and features before betting real cash. Experienced players often use free slots to learn about bonus features, RTP, volatility, and betting limits. Due to UKGC regulations, UK players can access and play casino slots for free only once they sign up and verify their account with the casino.
Slot Games with No Deposit
UK casinos offer attractive bonuses to entice new players and reward loyal ones. These include no deposit bonuses, which let you play top slot games for free. No deposit bonuses might give you bonus money when you sign up, free spins on featured slots, or both. Unlike demo mode, no deposit bonuses allow you to win real money, although you’ll usually need to deposit and meet wagering requirements to withdraw any winnings.
Online Slots Software
Top-tier software providers have had to up their game in recent years, facing ever-increasing competition from smaller studios eager to push the boundaries of innovation.
This has led to an evolution in the online slot experience for UK players, who have access to an unprecedented selection of online slot software, each aiming to deliver a distinct and memorable gaming experience.

Common Misconceptions about Casino Slots Online
There are myths and rumours about online slot machines that come from common suspicions that people have about online activities. Are online slots programmed to pay out at specific times? Do they pay out less after a player wins the jackpot? Are online slot games rigged and fraudulent? Let’s have a look at some these misconceptions.
- Online Slots are Easy to Win: This is an untrue myth. Although online slots statistically give a better chance to win in the long run due to a high RTP, this does not mean you will win. Every spin of the reels is entirely random and while slots may seem easy to play, that does not make winning more likely.
- Playing More Increases Chances to Win: Although in theory the more you play, the greater chances you have to win, that does not mean you will increase your chances to win per each individual spin, and winnings are never a guarantee. So the length of your session won’t affect your chances of landing big wins. Always have to bear in mind the randomness of each spin; just as you are likely to win more if you play longer, you are also likely to lose.
- Online Slots Don’t Pay Large Sums: Action speaks louder than words and if this was the case, millions of people wouldn’t be playing online slots. You can win huge amounts playing online slots, with millions of pounds being paid in prizes throughout the UK every week, and progressive jackpot slots that can pay millions to individual happy winners.
- Online Slots Are “Rigged”: There is a false myth about online slot games being rigged, allowing casino operators to control the game outcome. Every casino we feature on Gambling.com is licensed by the UKGC and as such, its RNG is fully certified and regularly tested to make sure that the outcome of every spin of an online slot game is random. So any slot we recommend on our site is never rigged.
