Bonus FAQ
What is a wagering requirement?
A wagering requirement (also called a playthrough requirement) tells you how many times you must wager your bonus before you can withdraw the winnings. For example, a £100 bonus with 30x wagering means you must place £3,000 in total bets before any winnings become withdrawable. Lower is better — look for 20x or under.
What does "no wagering" mean?
A no-wagering bonus lets you keep any winnings from free spins or bonus funds without meeting a playthrough requirement. These are rare but genuinely player-friendly. Casumo is one UK casino currently offering no-wagering free spins.
Can I withdraw my bonus money straight away?
Generally, no. Most welcome bonuses are subject to wagering requirements that must be met before withdrawals are possible. Always read the T&Cs before claiming a bonus. A few specialist casinos do offer no-wagering promotions.
What is a maximum bet rule?
When playing with bonus funds, most casinos limit your maximum stake to £2.50–£5 per spin or hand. Placing bets larger than this while using bonus funds can result in your winnings being voided. This rule is enforced by UKGC-licensed operators.
Do bonuses expire?
Yes. Most bonuses and free spins have an expiry date — commonly 7 or 30 days. If you haven't met the wagering requirements before expiry, the bonus (and any associated winnings) is forfeited. Check the T&Cs for the expiry period before claiming.
