21 Casino first launched in 2012 as part of the Caddell Group. It’s an online casino that keeps everything nice and simple, eschewing flashy gimmicks in favour of a gaming experience that’s as smooth as a beached pebble. It’s long held a UK gambling license and recently acquired a Swedish license, and offers a secure, safe, and heavily vetted environment where you can play a fine selection of games. Throw in some excellent bonus promotions including a 21 bonus spins no deposit required and 121% welcome bonus for new players and all the foundations are in place. But does 21 Casino build on them to become a true player favourite?

The 21 Casino site shows there’s something wonderfully reassuring about an online casino that isn’t afraid to keep it simple these days. But you know what? So many sites are obsessed with the ‘novelty’ value that they failed to appreciate that any casino that creates a seamless gaming experience is pretty novel anyway. Not so 21 Casino. Its interface is so intuitive that you’ll forget you’re playing at a new casino within five minutes of signing up. Plus, the casino looks great to boot.

It uses a predominantly black colour scheme with a splash of yellow and white, including a chalkboard background. It’s classy that design that blends a classic layout with a contemporary appearance. The casino games section is typically sleek, featuring tidily ordered games above a white grid, with several filtering options neatly arranged above them. The homepage is similarly uncluttered. It features a large but unobtrusive banner across the top, links to key sections via top and side menus, as well as a couple of other promo advertisements. Whatever the opposite of loud is, 21Casino is it.


The 21 Casino registration process takes about 1 minute 34 seconds from start to finish and includes high-level SSL encryption. Yes, we timed (we’re sad like that). The 21 Casino login asks you to select a username & password, share a few necessary contact details and then verify your account via an emailed link. You’re then ready to claim your welcome bonus (should you want it) and start playing. The 21 Casino login is an adequate (if necessary) user portal, which tells you your current cash balance, bonus amount and tracks your progress against any wagering requirements. The site is efficiently well laid out, so key sections are easy to find. You will, however, need to scroll down to the bottom of the page to see detailed information about the 21Casino terms and policies but that’s it’s hardly hassling. Especially given that most people don’t read them.

The games section features some interesting filters. You can browse the whole collection of course, but you can also display video slots vs classic slots, for example. Or only display the slots with the biggest jackpots if you prefer. We can’t make up our mind how useful it is, but it’s an apparent attempt to do something a bit different. The ‘promo’ section causes similar ambivalence. We assumed that it would filter down to the games currently subject to bonus offers. That’s not quite the case – it shows the latest releases and most popular slots. It’s still a good place to go if you’re looking for quick ideas though.


21 Casino games titles features hundreds from 51 different providers. The big software boys like NetEnt and MicroGaming are there of course, but there’s a nice selection of games from some of our favourite smaller studios like Blueprint Gaming, Aristocrat and Elk. The slots game catalogue is impressive once you delve into it. The video slots are supplemented by a small selection of jackpot games including NetEnt’s three popular titles – Mega Fortune, Arabian Nights and Hall of Gods. Microgaming’s Mega Moolah is, however, conspicuous by its absence. We know a lot of you love that one. 

Moving away from slots, 21Casino games boasts a diddy live casino with five different games including baccarat, roulette and blackjack games. Most gaming sites will include some level of live dealer games for those who want it these days, but in truth, there’s better to be found elsewhere if you crave the real-life action. The list of table games is fairly middling too (21Casino prioritises slots like so many others) but there is an interesting ‘High Roller’ section that will entice the serious gamblers amongst you. Remember to play sensibly, kids!

21 Casino recently updated the website to reduce the focus on dealer games. We are not sure why, but at least they have maintained the simple site design when so many other online gambling sites have gone the opposite and introduced more clutter.


Just like our very own 777, the number 21 is renowned in gaming circles, not least in Blackjack. 21 Casino’s name reflects its importance, and they’ve extended them to the first part of the 21 Casino welcome bonus. Spend that 1 minute 34 seconds registering, depositing and you’ll immediately receive a 121% bonus up to €300. Any winnings you make are added to your bonus cash, which is visible from your profile. The bonus spins are subject to x35 wagering requirements, as are the other elements of the welcome bonus. 


The 21 Casino no deposit offer is only available to no UK players. Thereafter their 1st deposit bonus is 121% up to €300. You can opt out of the welcome bonus if you prefer to play with your own cash and no wagering requirements form the start. We should also add that the description of the bonus elements in the drop-down when you deposit is weirdly formatted and it’s best the check the promo page (or this very review) for full details. The bonus of 121% up to €300 is now standard across the globe. 

The welcome bonus is for 18+. New players only. Minimum deposit of £10. Bonus funds are 121% up to £300 and separate to Cash funds. 35x bonus wagering requirements. £5 max bet with bonus. Bonus must be used within 30 days otherwise any unused bonus shall be removed. Terms Apply. BeGambleAware.org


The 21 Casino mobile casino for iOs devices and Android follows in the footstep of its big desktop brother. It’s a sleek, smart site that’s controlled by a straightforward menu and grants immediate access to an excellent game selection. It’s accessed via your device’s browser and optimised for iOS devices like iPads and iPhones, plus smartphones and tablets of all shapes and sizes.

The smart yet vivid colour scheme looks great, and there’s plenty of functionality included too. Again, we tested the live chat portal, and it worked correctly even late at night. There are no issues loading games or pages; everything is generally as it should appear. It’s an impressive cross-platform online casino.


Aside from being a classy online casino and a supremely comfortable gaming environment, 21 Casino also provides some perks for regular players. There’s a couple of recurring promos, which allow you to secure deposit bonuses on selected weekdays, although they aren’t exceedingly exciting. The loyalty scheme is well constructed though, and you can redeem your points in cash. The games selection is regularly replenished so be sure to check the new games section. Finally, customer service through live support is available from 9am-12am GMT every day. We contacted them right at the end of that timeframe and still got a response within an impressive 5 seconds. Those factors combined with the user-friendly site make 21 Casino a comfortable home for any online casino player.


We’re big fans of 21 Casino here at 777 Casino, and not just because of the way they combine numbers with their word ‘casino’ in their title. This site seems to fly under the radar a bit, but if you want a straightforward, modern, hassle-free casino online, then you should look no further. They have the variety of casino games and live dealer games any discerning player is seeking.

The welcome bonus is excellent although it could do with some more exciting regular promotions here and there. It caters to big spenders but is suitable for everyone thanks to the accessibility of its interface. It’s just a comfortable place to play and immediately makes you feel at home. It might lack the razzmatazz of some, but that’s precisely its charm. We think 21 Casino deserves a more significant reputation.
