    Bonus Verdict

    We recommend this 121% deposit bonus up to £100 from 21 Casino, the bonus percentage is quite generous and the maximum bonus amount is decent. The wagering requirement of 35x bonus is also standard industry practice. However, there are some restrictive terms that give me pause. The low £5 max bet with bonus funds will make it time-consuming to meet the playthrough. Overall, we cautiously recommend this bonus for slots-focused players who carefully manage their bankroll and have the patience necessary.

    New players only. Min deposit £10. Bonus funds are 121% up to £100 and separate to Cash funds. 35x bonus wagering requirements apply. Only bonus funds count towards wagering requirement. £5 max. bet with bonus. Bonus funds must be used within 30 days, otherwise any unused shall be removed. BeGambleAware.org -

    Bonus Verdict

    This recommended 21 Casino bonus grants new players 21 spins on registration to use on the popular Book of Dead slot game. The main appeal here is getting to play this slot for free with the extra spins for a shot at real money prizes.

What are 21 Casino Bonus Codes

21 Casino bonus codes are random numbers and letter combinations that need to be used while depositing to unlock unique rewards. They offer free play on slots like the Book of Dead and also offer the possibility to bet on live casino games.

As a new player at this online casino, you can get a big 21 Casino welcome pack that credits you with 121% deposit match bonus worth up to £100. This applies to your first deposit, and bonus funds are kept separate from cash funds. This bonus is subject to 35x wagering requirement and the minimum deposit required is £10. However, if you’re not a fan of wagering requirements, we suggest you try our no wagering bonuses selection.

This deal is limited only to players who are willing to make an initial deposit in order to claim it, so there’s some risk involved. You can also get similar offers if you check out our best bonuses complete selection.

How to Claim a 21 Casino Bonus Code

Before you claim your bonus spins or the deposit bonus, you will need to create an account. To get the welcome bonus, follow the process described below:

  1. Navigate to 21 Casino’s homepage and find the “Registration” page to create a free casino account.
  2. Enter your personal information, and choose a username and password.
  3. You will then get 21 Casino after validating your identity by uploading ID documents.

With an account, you can make a real money deposit (min deposit £10) to access the welcome bonus. Meanwhile, you get the free spins without making a deposit automatically. If you’re looking for similar bonuses, you will be able to claim other no deposit free spins from our complete list.

21 Casino No Deposit Bonuses

Separate from the deposit deal, there is a no-deposit sign up bonus from 21 Casino as well. With these promos, you can get 21 free spins on Book of Dead. A 35x bonus wager requirement applies to the winnings generated and the maximum withdrawable amount is limited to £100. It’s an excellent chance for new players to explore the casino and try new games using the funds generated from the spins.

21 Casino Bonus Codes Verdict

Now that you have read this review of what 21 Casino offers, you are ready to decide if it is the right platform for you. It undeniably has great slots and live casino games, but is it worth your while to claim a bonus?

The bonus from 21 Casino is highly generous, offering 21 bonus spins for free with a maximum bonus for depositing players of £100. However, there are some clear drawbacks to the bonus terms. You must wager the spins winnings and deposit match 35 times on the casino games where bonus funds count towards wagering. The extra spins also have limited winnings of £100, which is high considering it’s a risk-free deal. The welcome bonus is only available to newly registered players, but that’s a standard practice and existing players have separate rewards from the casino.

21 Casino Pros & Cons


  • 21 spins will be added automatically when you make an account
  • A low minimum deposit of £10 is required to claim the bonuses
  • Many players may only access a significant bonus on the first qualifying deposit.
  • The casino gives members a great range of online casino games to play with bonus funds.
  • You can make a deposit using a wide range of payment methods.


  • Bonus money is subject to harsh wagering requirements, and the bonus expires if your account is inactive.
  • Players who want to deposit less than £10 won’t get the main bonus.
