Understand the real value of any casino bonus before you claim it
See what your casino bonus is really worth
Wagering requirements (also called playthrough) are the number of times you must bet your bonus before you can withdraw winnings. For example, a £10 bonus with 35x wagering means you must place £350 in bets. Look for low or zero wagering for the best value.
Some casinos offer wager-free bonuses, meaning any winnings can be withdrawn immediately as cash. These are typically more valuable than higher bonuses with high wagering requirements. Look for the "Wager Free ✓" indicator in our calculator above.
Free spins have a set value per spin (usually £0.10). Match bonuses give you a percentage of your deposit as bonus cash. Both types can have wagering requirements, so always use our calculator to compare the real value of different offers before claiming.
