Reference
Reading a wagering requirement.
A wagering requirement is the multiple of the bonus (and sometimes the deposit) that you must stake before you can withdraw bonus winnings. 30× on a £20 bonus means £600 of staking, not £600 of losses. The lower the multiplier, the better the offer.
Slots usually contribute 100% to wagering. Live casino and table games typically contribute 10–25%. Some games contribute 0%. Always check the contributions table.
- 10×ExcellentRealistic to clear in a single session of normal play.
- 20×–25×FairStandard for spin-based welcome offers in the UK market.
- 35×BorderlineClearable, but expect to deposit additional funds to finish.
- 50×+AvoidIn our maths the bonus value is usually wiped out by the variance.
The four types of UK welcome offer
Deposit match. The operator matches a percentage of your first deposit up to a cap. "100% up to £100" means a £100 deposit becomes £200 of playable funds, with the £100 bonus portion subject to wagering.
Free spins. A pack of spins on a named slot, usually at the minimum bet (£0.10–£0.20). Winnings are usually paid as bonus funds with their own wagering attached, occasionally as cash.
Bonus on stake. Increasingly common in 2026: "Spend £10, play with £40". The difference between deposit and play funds is bonus money with wagering attached.
Free bet / no-deposit token. Less common at casinos than bookmakers. Useful for trying a brand without commitment, but tokens almost always carry maximum-cash-out caps.
Five things to check before you click "claim"
- Wagering multiplier. Anything above 35× is rarely worth the effort.
- Game weighting. If you mainly play live blackjack, a slots-only bonus is not for you.
- Max bet during wagering. Often £5. Stake more and the bonus is voided.
- Expiry window. Seven days is tight. Thirty days is comfortable.
- Maximum cash-out. Some bonuses cap your eventual withdrawal regardless of winnings.
When not to take the offer
If you only want to play a few spins and walk away with whatever lands, decline the bonus at deposit. Bonus funds are paid out first and locked behind wagering — taking the offer can mean you cannot withdraw your own deposit until you have staked it through. You can always claim the offer on your second deposit instead.
