Last verified: March 2026 | Operator: LeoVegas Gaming PLC | UKGC Licence: 39198
21 Casino has over 1,200 games from 60+ providers. That's a bigger library than most UK casinos, which tend to sit in the 800–1,000 range. You'll find video slots, classic slots, table games, live dealer tables, jackpot slots, and game shows — all playable in the browser without downloading anything.
Slots take up the bulk of the catalogue — around 900+ titles from NetEnt, Pragmatic Play, Play'n GO, Microgaming and others. The live section is all Evolution Gaming: roulette, blackjack, baccarat, plus game shows like Crazy Time and Lightning Roulette, running round the clock.
A good chunk of the slots can be played for free in demo mode — no account needed, no deposit. Handy if you want to try a game out before putting money on it. Live tables and game shows need a funded account though.

Progressive Jackpots
There are 30+ progressive jackpot slots available. Mega Moolah (Microgaming) is the big one — it's paid out some of the largest jackpots in online casino history, regularly topping £1 million. Divine Fortune (NetEnt) and Major Millions (Microgaming) are the other popular picks.
Jackpot Tip
Jackpots hit randomly — there's no trick or strategy to trigger them. On some games, betting more can improve your shot at the top prize, but that depends on the specific title. Check the game rules before playing. And remember: only play with money you're happy to lose.
Key Providers
Mobile Gaming
There's no 21 Casino app for iPhone or Android. Everything runs through the mobile browser — the site resizes to fit your screen and all games work the same as on desktop. Just open Safari, Chrome or whatever you use and go to the site. No download needed.
New players can use the 121% welcome bonus on eligible slot games. The 10 no-deposit free spins are specifically for Book of Dead. Check payment options for how to fund your account — registration takes under five minutes.
