Great Britain · 18+. Reviewed 5 October 2026. Examples are illustrations, not offers or predictions.
A headline bonus is a conditional reward, not an increase in your spending budget. For readers in Great Britain, start with the current regulatory ceiling, then calculate the actual turnover and check what happens to your own money.
What changed on 19 January 2026
GB licensees cannot apply bonus-fund wagering requirements above 10 times. An incentive also cannot combine more than one gambling product: betting, casino, bingo or lottery. A casino offer and a separate sports offer are not automatically one prohibited incentive; check what activity earns each reward. Historic 30x–50x examples and overseas terms should not be used as the standard for a new GB offer.
Calculate the requirement before you accept
| Illustrative £20 bonus | Qualifying turnover | Meaning |
|---|---|---|
| 0x | £0 | No bonus playthrough, but eligibility and payment checks still apply |
| 5x | £100 | £20 × 5 |
| 10x | £200 | £20 × 10 |
These figures assume bets contribute 100%. If a game contributes 20%, a £1 bet earns only 20p of progress; £200 of qualifying credit would require £1,000 in actual stakes. The contribution rate matters as much as the multiplier. Do not apply a deposit-plus-bonus formula without checking the terms and whether that calculation complies with the GB rule.
Read five conditions together
- Reward type: bonus credit, free-spin winnings or cash? Is there an opt-in or qualifying deposit?
- Eligible games: excluded titles and contribution percentages change the calculation.
- Maximum bet: a promotion can restrict stakes while bonus funds are active.
- Expiry: distinguish the time to claim, use spins and finish any playthrough.
- Withdrawal effect: understand which bonus funds disappear if you withdraw cash or cancel the promotion.
Ask the operator to identify separately your cash deposit, cash winnings, restricted bonus and bonus winnings. Do not assume a bonus condition gives the operator unrestricted control over your own cash. If a withdrawal is refused, request the exact clause and a written explanation.
Why a smaller multiplier still costs money
At a hypothetical 96% RTP, £200 of completed turnover has a theoretical expected loss of £8. This is an average mathematical cost for that turnover, not an £8 cap, guaranteed profit from a £20 reward or a forecast that you will complete the offer. You can lose your balance before finishing. Increasing stakes to meet a deadline increases exposure.
Save the specific terms when claiming. Declining a bonus is a reasonable choice if the restrictions do not match the amount or time you intended to spend.
