21 Casino Review 2019 - Slots and Games.

21 Casino offers new players a 121% matched deposit bonus up to a maximum of £300. What this means, is that - the amount of money you deposit into 21 Casino will be doubled by the site. Let’s say you create an account and make a deposit of £40. 21 Casino will then give you an additional £40, bringing your total account balance up to £80! The wagering requirements for this bonus are just 35X too, so you stand a really good chance of actually converting the bonus into real, withdrawable cash.

Now, as 21 Casino’s main welcome bonus is tailored to UK-based players, you’ll be pleased to learn that the bonus is also a parachute bonus. What this means, is that you'll find yourself able to withdraw any winnings that you win - while playing your cash balance. If you do land a nice-sized win, you can simply ‘drop’ the bonus funds and make a cashout!

21 Casino Bonus Codes

21 Casino do not use bonus codes. Or, at least, they haven’t done in a while - and it’s unlikely that we’ll see them making a return in the near future. If you’d like to claim the bonus, then the only thing that you need to do is tick the relevant box when you go on to actually make a deposit.

21 Casino No-Deposit Bonus

At the time of writing, 21 Casino does not offer any form of no-deposit bonus to UK Players. In some cases, we’d say this was a disappointment - but 21 Casino offers such a generous welcome bonus offer that in this scenario we’re not overly bothered.

Loyalty Royalty

21 Casino’s Loyalty Royalty program is incredibly generous and allows you to build up loyalty points every time you play one of their games (for real money.) You don’t need to opt-in to this promotion either, as all players are automatically signed up for it. Essentially, you’ll earn between 0.25 and 2.00 loyalty points for every £10 you wager on one of the games at 21 Casino. Once you’ve collected more than 200 of these points, you can start to redeem them for real cash. Every 200 points you accumulate is worth £1 in bonus money, so you can see how quickly they can start adding up!
