How to Compare Casino Bonuses
Check the wagering requirement
Divide the bonus amount by the wagering requirement to find the implied house edge on the bonus. A 30x wagering requirement on a £100 bonus means you need to bet £3,000 before withdrawing.
Review the game weightings
Not all games contribute equally towards clearing a bonus. Slots typically contribute 100%, while table games may only count 10–20%. If you prefer roulette or blackjack, check this before claiming.
Note the maximum withdrawal cap
Many bonuses cap the maximum amount you can withdraw from bonus winnings — often at £100–£500. If you have a large win, you may only be able to keep a fraction of it.
Check the expiry period
Bonuses expire, usually within 7–30 days. If you cannot meet the wagering requirement within the timeframe, your bonus balance and any winnings will be forfeited.
Bonus FAQs
A wagering requirement is the number of times you must bet through bonus funds before you can withdraw any winnings. For example, a £50 bonus with 30x wagering means you must wager £1,500 before cashing out. We always display the full calculation.
No-deposit bonuses are great for trying a casino risk-free, but they almost always carry higher wagering requirements and strict win caps. Always read the terms before using them.
A match bonus multiplies your deposit amount (e.g., 100% up to £100 doubles your first deposit). Free spins award a fixed number of spins on specific slot games. Many welcome offers combine both.
Welcome bonuses are typically limited to one per household or payment method. Attempting to claim the same offer multiple times violates operator terms and may result in account closure.
This varies by operator but is typically between 7 and 30 days. Unused bonus funds and any winnings generated will be forfeited if you do not meet the requirements within the stated timeframe.
