If you’re a UK slot player searching for the most entertaining and rewarding video slots of the year, you’re in the right place. We’ve handpicked the best online video slots that you can find at UK casinos in 2025 – from legendary classics to fresh releases with game-changing features.

TOP Video Slots to Play at UK Online Casinos (2025)

These are the slots that keep you coming back for one more spin. Whether you love mythological adventures, wild-west thrillers or quirky fruit machines, this list is your shortcut to the top games worth playing right now.

Thunderstruck II (Microgaming)

Few slots have stood the test of time like Thunderstruck II. Since its release in 2010, it’s been my go-to. With its epic Norse mythology theme and solid gameplay, it set the standard that many have tried (and failed) to copy.

The Great Hall of Spins bonus is the amazing. As you unlock new levels, the game changes with free spins tied to Norse gods like Loki, Odin and Thor. Add in 243 ways to win, a high variance format, and a decent RTP, and it’s still one of the most engaging UK slots around.

Theme: Norse Mythology
Studio: Microgaming
Default RTP: 96.65%
Max Win: 8,100x
Volatility: High
Min/Max Bet: £0.30/£15

Book of Dead (Play’n GO)

Book of Dead is arguably the most famous “Book” slot ever made – and it’s still wildly popular with UK players in 2025. The Indiana Jones-style theme, high volatility, and iconic expanding symbol feature in free spins make it a go-to game for thrill-seekers.

It’s a simple slot, but highly effective. One lucky expanding symbol during the bonus round can lead to massive wins, especially if you land Rich Wilde across the reels.

Theme: Ancient Egypt
Studio: Play’n GO
Default RTP: 96.21%
Max Win: 5,000x
Volatility: High
Min/Max Bet: £0.10/£50

Big Bass Bonanza: Hold & Spinner (Reel Kingdom)

This 2025 revamp of the classic Big Bass series brings fresh energy. With the new Hold & Spinner mechanic, you get more win potential in the base game and more chances to trigger the bonus with big instant cash prizes.

The fishing theme still holds strong appeal, and the retro design combined with modern features like buy bonus rounds keeps it fresh.

Theme: Fishing
Studio: Reel Kingdom
Default RTP: 96.07%
Max Win: 10,000x
Volatility: Medium-High
Min/Max Bet: £0.10/£10

Starburst XXXtreme (NetEnt)

One of the most recognisable slots ever has had a serious power-up. Starburst XXXtreme takes the core features of the classic and dials everything up – higher volatility, bigger max wins, and the same iconic wild re-spins.

If you’re a fan of sleek visuals, simplicity, and the thrill of a very volatile payout, this one is a must.

Theme: Space/Jewels
Studio: NetEnt
Default RTP: 96.26%
Max Win: 200,000x
Volatility: Extreme
Min/Max Bet: £0.10/£50

Razor Returns (Push Gaming)

The 2025 sequel to the cult hit Razor Shark, Razor Returns adds even more edge with new multipliers, improved graphics and higher win potential. It’s not for the faint-hearted, but it’s a favourite among high-volatility fans.

Land the mystery symbols and hit the Nudge & Reveal feature to open up some really nice payout possibilities.

Theme: Underwater/Action
Studio: Push Gaming
Default RTP: 96.55%
Max Win: 100,000x
Volatility: Very High
Min/Max Bet: £0.10/£20

Money Train 4 (Relax Gaming)

The Money Train series keeps getting better. Money Train 4 is a feature-packed release with a mind-blowing 150,000x max win. The bonus round remains the star – especially when the persistent symbols line up for insane combos.

This is one for bonus buy fans and players who like heavy risk/reward action.

Theme: Wild West/Cyberpunk
Studio: Relax Gaming
Default RTP: 96.1%
Max Win: 150,000x
Volatility: Extreme
Min/Max Bet: £0.10/£60
