SlotHow to Actually Clear a Casino Bonus (Meet the Wagering)
Claiming a bonus is easy. Actually clearing it — turning locked bonus money into cash you can withdraw — is where most players get stuck. The rules are usually buried in the terms and conditions, and they are designed to make the bonus harder to complete than the headline “100% up to £X” suggests. This guide walks through exactly what you have to do, in plain English, so you can decide whether a bonus is worth your time before you deposit.
If you are completely new to this, start with our beginner’s guide to online casinos first, then come back here.
What “wagering requirement” and “playthrough” mean
The wagering requirement (also called playthrough or rollover) is the total amount you must bet before your bonus and any winnings from it can be withdrawn. It is quoted as a multiple — for example 35x.
The single most common beginner mistake is reading “35x” as “I place one bet 35 times bigger”. It means the opposite: you must place bets totalling 35 times the qualifying amount. That “qualifying amount” varies by casino:
- Bonus-only wagering: the multiple applies to the bonus alone.
- Deposit + bonus wagering: the multiple applies to both added together — roughly double the turnover.
The difference is huge, so always check which one applies. Bonus-only is far friendlier than deposit-plus-bonus at the same headline multiple.
A worked conceptual example
Let’s keep the numbers generic — every casino is different, so treat this as a method, not a promise.
Suppose a bonus is B with Nx wagering on the bonus only. Your total required turnover is:
Turnover = B × N
If a bonus were, say, £50 with 35x wagering, you would need to bet 50 × 35 = £1,750 in total before withdrawal. That is not £1,750 out of your own pocket — it is £1,750 of cumulative bets, recycled as you win and re-stake. But every time money passes through a game, the house edge takes a small slice. Over £1,750 of turnover on a slot with, say, a 4% house edge, the expected cost of that turnover is around £70 — more than the bonus itself.
Now apply deposit + bonus wagering instead. If you deposited £50 and got a £50 bonus, 35x on the combined £100 means £3,500 of turnover — double the grind for the same headline offer. This is why the small print matters more than the big number.

How game weighting works
Not every bet counts equally toward the wagering. This is game weighting, and it quietly decides whether a bonus is realistic or nearly impossible.
- Slots usually count 100% — £1 bet clears £1 of wagering.
- Table games (blackjack, roulette, baccarat) often count 10%, 5%, or 0%. If blackjack counts 10%, a £1 bet only clears 10p of the requirement — so you would need ten times the turnover to clear it that way.
- Live dealer, video poker, and some jackpot slots are frequently excluded entirely, meaning bets there do nothing for the wagering.
Casinos weight low-edge games (like blackjack, which a skilled player can bring close to even) down to near zero precisely because you could otherwise clear the bonus cheaply. The weighting table is usually the most important paragraph in the whole terms document. Read it before you assume your favourite game qualifies.
Max-bet rules while wagering
Almost every bonus caps the maximum bet you can place while wagering is still outstanding — commonly around £5, though it varies. Breach it, even by accident, and the usual penalty is severe: the casino can void the bonus and all winnings from it. No warning, no partial credit.
This rule exists to stop players placing one large bet to swing for a big win and cash out fast. Practical protection:
- Note the max-bet cap before your first spin and stay well under it.
- Remember the cap can apply per spin and to features like “bet all lines” or buy-a-bonus stakes.
- If you are unsure whether a bet type counts, ask support in writing before you play.
The expiry clock
Bonuses come with a deadline — often 7 to 30 days — to complete the full wagering. When it expires, the bonus and any unwithdrawn winnings tied to it typically disappear.
This turns the maths from “can I clear it?” into “can I clear it in time without over-betting?”. A large turnover requirement on a short clock effectively forces bigger, riskier bets, which increases the chance you lose your balance before you finish. A generous-looking bonus with a tight expiry can be worse than a modest one with a relaxed window. Always divide the required turnover by the days available and ask honestly whether that pace is sensible for your bankroll.
The honest reality: high wagering often isn’t worth clearing
Here is the part most affiliate sites won’t tell you. Bonuses are marketing. Once wagering climbs high — and once you factor in weighting, the max-bet cap, the expiry clock, and the house edge grinding away across all that turnover — the expected value of a high-wagering bonus is frequently negative. You are statistically likely to lose your deposit trying to clear it.
A useful rule of thumb: a smaller bonus, or no bonus at all, that leaves you in full control of your money often beats a large bonus you are unlikely to complete. If a casino’s headline offer is enormous but the wagering is 50x on deposit-plus-bonus with a 7-day clock and slots-only weighting, that is a signal to walk away, not to deposit more.
If you want help comparing offers on their real terms rather than the headline, our AI casino finder reads the fine print for you and surfaces the wagering, weighting, and caps side by side.
Bottom line
Clearing a bonus is a maths problem, not a game of hope. Before you deposit, check four things: the wagering multiple and what it applies to, the game weighting, the max-bet cap, and the expiry window. Multiply it out. If the honest expected value is negative — and for high-wagering offers it usually is — the smartest move is to skip the bonus and play only with money you fully control. A bonus you can’t realistically clear isn’t free money; it’s a reason to over-play. Keep your stakes within your means and treat any bonus as a bet, not a gift.
