Highest paying slot games for UK players

Not all online slots are created equal, with some offering better chances of a payout than others. While there’s no way of guaranteeing a win, choosing slot games with higher return to player percentages (RTP) will theoretically give you a better chance at winning real money. 

RTP is displayed as a percentage and indicates how much of your money you can expect to get back when playing a casino game over time. The industry average is 96%, but the best online slot payout percentages are 98% and higher. Give these high-paying slots a try to increase your chances of winning when you spin the reels:

1. Book of Dead

Rich Wilde is the main character in this Indiana Jones-style slot. Book of Dead is a fan favourite, boasting a decent 96.21% RTP, and in-game bonuses including wilds, scatters and a special expanding symbol that will trigger a payout worth 5,000x your stake when it covers the entirety of the reels!

2. Big Bass Bonanza

Big Bass Bonanza is so successful that it’s spawned numerous sequels, including our all-time favourite Bigger Bass Bonanza. The original has a fun fishing theme, immersive soundtrack and various bonus features, including scatters, free spins and re-triggers to enhance gameplay.

3. Starburst

Set against a cosmic backdrop, Starburst is an iconic slot from leading slot provider NetEnt. The 5-reel, 10-payline slot has a 96.09% RTP and is optimised for play on all devices, including iPhone and Android. While it’s classic in style, it remains a top pick for gamblers thanks to its simple gameplay and low volatility, meaning you’re likely to enjoy small but frequent wins. 

4. Cleopatra

Cleopatra is a popular ancient Egyptian-themed slot featuring classic cultural symbols such as the Sphinx, river Nile and hieroglyphics. While it has a mid-range RTP of 95.02%, the max win of 10,000x your bet makes it hard to pass up on. You can boost your payout by triggering the various unique features, which include wilds, scatters and free spins.

5. Big Bass Splash 

Big Bass Splash is one of the most popular titles in the ‘Big Bass’ series from Pragmatic Play. On this fishing adventure, you’ll need to hook the various symbols to land a payout. The wild and the scatter are the most valuable, with five scatters triggering a free spins round that could see you win 5,000x your bet.

6. Rainbow Riches

Rainbow Riches appeals to high rollers and casual players alike due to its wide betting limit. You can spin the reels for as little as £0.20 all the way up to £500 per spin. The game offers three different bonus games – Road to Riches, Wishing Well and Pots of Gold – all of which offer a top prize of 500x your stake. There’s also an autoplay feature for those of you who want to watch the reels play out without lifting a finger.

7. Dead or Alive

Released in 2009, Dead or Alive is an innovative NetEnt slot with a gunslinger theme. Prolific outlaws such as Jesse James and Billy the Kid are the slot’s special symbols and will appear on ‘Wanted’ posters. These wilds become sticky during the free spins bonus game to offer wins of over 13,000x your stake!

8. Immortal Romance

Immortal Romance is a fun vampire-themed game with top-notch graphics and a higher-than-average 96.86% RTP. There are 243 ways to win in this Microgaming slot, which also features a Wild Desire bonus that could pay out 12,000x your bet.

9. Gonzo’s Quest

Join Gonzo in his quest to uncover the lost city of Eldorado in this popular NetEnt slot. The 5x3 reels feature Peruvian-inspired symbols, high-quality graphics, an immersive soundtrack and plenty of bonus features. The Free Fall bonus is where the real fun begins, with an Avalanche feature that applies multipliers of up to 15x, leading to potential wins of 37,500x.

10. Break Da Bank Again

Break Da Bank Again is a popular Microgaming slot with a mid-range RTP of 95.43%. The money heist-themed slot has low betting limits of £0.01 to £22.50 per spin, making it an ideal choice for budget bettors. There’s also a rewarding free spins bonus game that can award 15, 20 or 25 free spins based on whether three, four or five scatters are in view.

How to win online slots

There’s no way to guarantee a win when playing online slots, as they all use random number generator (RNG) technology to ensure that outcomes are unpredictable and fair. That said, these expert tips will help maximise your playing experience:

  1. Choose the right slot:  When getting started, play slots with high RTPs and bonus features, as this will help boost your chances of winning a payout.

  2. Practice for free:  There are plenty of demo slots that you can play for free online. Playing for free will help familiarise yourself with a game’s mechanics before you place real money bets.

  3. Stick to your budget:  Responsible gambling means never betting what you can’t afford. Set a budget and stop playing once you reach it.

  4. Claim casino bonuses:  Bonuses and promotions will boost your bankroll and extend your gaming session.

  5. Check the paytable:  All slots have a unique paytable showing the values of the symbols featured in the game. Study this so you know which ones are the most valuable.
