Our review of 21 Casino

A slick black and grey styled casino site, 21 Casino could be the perfect home for a slots player who also loves casino games. On desktop, the layout centres around a single page rather than redirecting to different pages, so if you hate flicking back and forth waiting for pages to load, this will suit you nicely. The site is even easier to use on mobile, with a sliding menu of games to explore.

Welcome Offer

When you sign up to 21 Casino, you’ll be offered their welcome bonus. This has a minimum deposit of £10, and will give you 121% bonus up to £300. See the promotional page for more details.


There is (at time of writing) a reload bonus available every week; you’ll get a 21% bonus on your first deposit of the day every Monday and Tuesday. The big promotion at the moment is far more exciting- 21 Casino are giving away a holiday! One lucky winner will win a ski trip for them and a +1, including tickets to a music festival! Now that’s what we call a prize!Other bonus promotions are also available; there is currently an offer called the Stairway Bonus in which different deposit amounts give increasing numbers of free spins, depending on how much you’d like to deposit. You can check out all the promotions on offer on the specially-dedicated promotions page.


With this being a casino site, we were pleased to see lots of table games available, as well as variations with live dealers for those who want the real casino experience. There is a huge slots catalogue to choose from, and you can search by title if you know what you’re looking for. High rollers will enjoy the selection of jackpot games, where you could win the big bucks if you’re lucky enough to break the jackpot. There are also plenty of scratch card style games which can be found in the “Lottery” section.
