The UK’s Best Slots Games and Where to Play Them 2025

Many slots are themed around animals, ranging from those you’ll find on an African safari in Mega Moolah to mischievous bulldogs in The Dog House Megaways. Fishing slots are a particularly popular sub-category on this front, with the Big Bass and Fishin’ Frenzy series among the most popular slots right now at top UK casinos including Winomania.

🕵️ Expert recommendation: The Dog House Megaways has an RTP of 96.55% and max win of 12,305x your bet, meaning the Pragmatic Play release beats other popular animal-themed Megaways slots like Buffalo King Megaways and 5 Lions Megaways on both fronts. This is partially because the free spins mini game features both wild multipliers and sticky wilds on every spin.

There are lots of slot games that take you back to the wild west, with symbols and features based around cowboy and cowgirl outlaws, sheriff’s badges and wanted posters. Often, the reels overlook dusty towns and taverns with upbeat folk-based soundtracks to add to the excitement. Coral has over 15 wild west-themed slots to choose from, including Wild West Bandits and 2 Wild 2 Die.

🕵️ Expert recommendation: Wanted Dead or a Wild by Hacksaw Gaming features the unique DuelReels mechanic, whereby scatters expand to fill the entire reel and award you the higher of two multipliers (which can reach 100x). The top prize of 12,500x offers better maximum returns than other well-known titles like Dead or Alive (12,000x) and Wild West Gold Megaways (5,000x).

You can spin the reels with the luck of the Irish on your side, with lots of slots starring leprechauns, four-leaf clovers, pots of gold and other icons of Irish folklore. The Irish-inspired Rainbow Riches slots series is available at top-rated sites such as Betway Casino and Grosvenor Casino.

🕵️ Expert recommendation: 9 Pots of Gold puts an Irish spin on the cash collect mechanic with the special gold pot symbols, which award an instant prize of up to 2,000x your bet if you get three or more on the same spin. With a generous hit rate of 39.75% (or nearly 2 wins from every 5 spins), it also pays out more frequently than both Clover Fortunes and Book of the Irish.

Ancient Egypt is one of the longest-running slots themes, after initially proving popular at UK casinos with iconic games such as Book of Ra (released back in 2005) and Cleopatra (2012), which are both still among the most played slots by Brits. Today, it’s still going strong thanks to the likes of the Rich Wilde series, which provides fun slots based around pyramids and temples, Egyptian gods, hieroglyphics and more.

🕵️ Expert recommendation: 4 Secret Pyramids by 4ThePlayer not only has a much bigger top payout (55,000x) than staples like Book of Dead (5,000x) and Cleopatra (10,000x), but uses the innovative BonusUp mechanic. That means every time you trigger free spins you get an improved bonus from the time before, up to a maximum of 55 free spins with a 15x multiplier.

There are dozens of online slots set in ancient Greece, featuring symbols and bonuses based around mythical gods such as Zeus and Athena. Among the most popular at UK casinos is Pragmatic Play’s Gates of Olympus series, which has spawned numerous spin-offs such as Gates of Olympus 1000 and Gates of Olympus Super Scatter. Age of the Gods by Playtech is also a beloved progressive jackpot title with slots fans.

🕵️ Expert recommendation: Relax Gaming’s Book of 99 has the joint-highest RTP (99.00%) of any online slot at UK gambling sites, plus a higher max win of 5,000x your bet than its counterpart Mega Joker. Unlike other ancient Greece-themed slots, it also gives you two ways to activate free spins, as you can do so by landing three or more scatters or alternatively filling the progress bar via collecting wilds.

If the likes of ghosts, vampires and dark fantastical characters are your thing, you’re spoilt for choice with the gothic-inspired slots available at UK gambling sites. Many of these boast above average RTPs and maximum wins, most notably Immortal Romance (96.86% RTP and a top prize 12,150x of your bet) and RIP City (96.22% and 12,500x). Software providers such as Hacksaw Gaming specialise in horror-themed slots.

🕵️ Expert recommendation: Madame Destiny Megaways boasts a maximum of 200,704 paylines, putting it in the top 5 Megaways slots with the most ways to win. On top of that, the free spins round comes with multipliers of up to 25x – more than double the 10x you can get on slots renowned for this feature like Big Bass Splash – while wilds automatically double any wins.
