Wagering Requirements — How To Read A Bonus Before You Accept It

Published: 4 August 2026

Offshore welcome offers look far larger than UK ones because there is no cap on advertised value. A "£3,250 bonus" is a match spread across several deposits, not cash in your account.

The three terms that actually matter

Game weighting

Not every game clears wagering at the same rate. Slots normally count 100%, table games 10%, and live dealer games often 0%. Playing blackjack to clear a slots bonus can mean you make no progress at all.

A worked example

A £100 deposit with a 100% match at 40× wagering on the bonus means £4,000 of turnover before withdrawal. At £2 a spin that is 2,000 spins. At the 96% average RTP, the expected cost of clearing it is around £160 — more than the bonus is worth.

This is not an argument against bonuses. It is an argument for reading the multiplier before you click accept.

How the arithmetic actually works

Wagering is expressed as a multiplier, and the first thing to establish is what it multiplies. There are two conventions and the difference is a factor of two.

Basis£100 deposit + £100 bonus at 35×Turnover required
Bonus only35 × £100£3,500
Deposit + bonus35 × £200£7,000

The same advertised "35× wagering" therefore means either £3,500 or £7,000 of play depending on a single word in the terms. Always find which basis applies before accepting.

What clearing a bonus actually costs

Turnover is not loss, but it has an expected cost, and that cost is calculable: turnover × (1 − RTP).

TurnoverAt 96% RTPAt 94.5%At 92%
£3,500£140£193£280
£7,000£280£385£560
£8,000£320£440£640
£12,000£480£660£960

Set that against the bonus. A £100 bonus at 35× on deposit+bonus costs an expected £280 to clear on a 96% game. The offer is worth less than the cost of collecting it, which is why most players never complete one — and why operators can advertise them at that size.

Game weighting — the multiplier behind the multiplier

Not every game clears wagering at face value. A £10 bet on a game weighted at 10% contributes £1 towards the requirement.

Game typeTypical weighting£1,000 of play contributes
Slots100%£1,000
Slingo and scratch cards50–100%£500–£1,000
Roulette10–20%£100–£200
Blackjack5–10%£50–£100
Live dealer0–10%£0–£100
Video poker0–20%£0–£200

The reason is house edge. Blackjack at 0.5% would let a player clear a bonus at almost no expected cost, so operators either weight it near zero or exclude it outright. If you intend to clear a bonus, you will be playing slots — the terms make sure of it.

The max bet rule, and why it voids more withdrawals than anything else

Almost every bonus caps the stake permitted while wagering is active, usually at £5. Exceed it — once, even accidentally — and most operators void the bonus and everything won from it.

This catches people constantly for a specific and avoidable reason. On a site with no UKGC stake cap, raising your stake mid-session is effortless, and a bonus buy at 100× your stake almost always breaches the limit in a single click. Autoplay set before the bonus was credited is the other common route.

The clauses that catch people out

Maximum cashout

Common on no-deposit and free-spin offers: winnings capped at 5× to 10× the bonus regardless of what you actually win. A £10 free-spins offer with a £50 cap means a £2,000 win pays £50.

Expiry

Bonuses expire, usually in 7 to 30 days. An £8,000 turnover requirement inside seven days is not a bonus — it is a decoration.

Bonus-first or cash-first

Some operators play your cash balance first, so you can withdraw before touching the bonus. Others play the bonus first, locking everything. The second is much worse and is rarely advertised.

Excluded games

Jackpot slots and certain high-RTP titles are frequently barred entirely. Playing one while a bonus is active can void it in the same way a max-bet breach does.

When a bonus is genuinely worth taking

  1. The multiplier is 25× or lower, on the bonus alone rather than deposit plus bonus.
  2. There is no maximum cashout, or it is high enough to be irrelevant.
  3. The expiry gives you realistic time for the turnover involved.
  4. Slots weight at 100% and the titles you actually play are not excluded.
  5. You were going to play that volume anyway. This is the one nobody is honest with themselves about, and it decides everything.

If any of those fail, declining the bonus and keeping a withdrawable balance is usually the better decision. A wager-free offer a tenth of the size is frequently worth more.

A worked example, start to finish

The clearest way to see how these terms interact is to follow one bonus through.

You deposit £100. The offer is 100% up to £100 at 35× wagering on deposit plus bonus, slots at 100%, £5 max bet, 30-day expiry, no cashout cap.

  1. Balance: £200 — £100 yours, £100 bonus.
  2. Turnover required: 35 × £200 = £7,000.
  3. At £2 a spin that is 3,500 spins. At roughly 500 spins an hour, seven hours of play.
  4. Expected cost of £7,000 turnover on a 96% slot: £280.
  5. Expected outcome: you finish with roughly £200 − £280, which is below zero. The requirement is not designed to be completed profitably.

Now change one variable. At 25× on the bonus alone, turnover is £2,500 and the expected cost is £100 — against a £100 bonus. That is break-even, and it is roughly where a bonus stops being a marketing device and starts being an offer.

Practical rules that hold up

When declining is the right call

Most of the time, for most players. A bonus converts a withdrawable balance into a locked one, and the lock is worth more to the operator than the bonus is to you unless the multiplier is genuinely low.

If you are depositing to play an evening and would like to keep whatever you have left afterwards, decline. If you are depositing to grind out several thousand pounds of turnover regardless, a low-multiplier bonus is worth taking. Very few people are honestly in the second category.
