35x Wagering Requirement
2/5
21 Casino’s bonuses have a 35x wagering requirement, meaning you must wager the bonus amount 35 times before withdrawing any winnings. This requirement reduces the real money value of the bonus, making withdrawals more challenging compared to no-wagering offers.
Explore our No Wagering Casino Bonuses for bonuses that let you withdraw your winnings without wagering.
Competitive Bonus Amount
3/5
The 21 free spins from 21 Casino offer a fair chance to win real money with no deposit required. The 121% deposit bonus up to £100 further boosts your initial funds, making this bonus combination competitive in the UK casino market.
£100 Max Win Limit for Free Spins
1/5
The free spins at 21 Casino have a win cap of £100, limiting the maximum withdrawal from free spin winnings. However, the deposit bonus up to £100 offers more substantial withdrawal potential within the bonus limits.
