Types of casino bonus

Understanding wagering requirements

A wagering requirement (or "playthrough") is the number of times you must stake the bonus amount before you can withdraw winnings derived from it. A 35x wagering requirement on a £100 bonus means £3,500 of total stakes - typically on slots that contribute 100%.

Two bonuses with the same headline can deliver wildly different value. A £50 bonus at 10x wagering is mathematically far more valuable than a £200 bonus at 60x with a £5 max-bet cap. We score every bonus on real expected value, not face value.
