How would you like to browse?
Five ways into the catalogue, depending on how you shortlist. Browse all slots to scan everything, newest first. Filter by theme if you know the setting you're after, such as Egyptian, fishing or Greek mythology. Filter by mechanic for a specific engine: Megaways, Hold and Win, Cluster Pays. Filter by attribute if you shortlist by exact spec: RTP, reel count, paylines. Or filter by provider if you follow particular studios. Each hub explains the category and lists the reviewed slots in it.

Themes
Slot themes
Themes group games by setting, from Egyptian tombs and fishing trips to Irish luck and classic fruit machines. Each theme page lists the reviewed slots that share it. Theme is the broadest filter on the site: useful for browsing, less precise than filtering by RTP or mechanic.

Mechanics
Browse by mechanic
Slot mechanics decide how wins are formed. Megaways, Hold and Win, Cluster Pays, Cascading and the rest: pick by the engine driving the slot rather than the theme on top. Each mechanic page explains how the device works and lists the reviewed slots that use it.

UK regulation
UK slot rules in brief
What changes when a slot runs at a casino licensed by the Gambling Commission.
Stake limits
Online slot stakes are capped at £5 per spin for players aged 25 and over (from 9 April 2025) and £2 per spin for players aged 18 to 24 (from 21 May 2025). GB-licensed casinos apply the cap whatever bet range the studio builds into the game.
RTP versions
Studios often release one slot in several RTP versions, and each casino chooses the version it runs. The figure that applies is the one in the game's own help or paytable screen at that casino.
Bonus buy
In January 2020 the Gambling Commission had GB-licensed operators remove paid feature buy-ins from slots, citing social-responsibility concerns. Studios still build the option for other markets, so a review may describe it.
