Wagering 10x vs 35x

Wagering 10x vs 35x: the short version

Wagering, sometimes called playthrough, is the total amount you must stake before bonus funds turn into withdrawable cash. The multiple tells you how many times over the bonus has to be played. Because every stake carries the game's house edge, more wagering means more average cost. At 10x that cost is a fraction of the bonus. At 35x it is larger than the bonus itself on most slots.

That gap is the reason UK rules changed. If you see 35x today, it is either an old screenshot, a non-UK site or a misunderstanding of the terms. Our wagering requirements guide covers the basics, and this page sits with our other bonus comparisons.

10x vs 35x wagering on the same bonus, worked through

Every row uses a 96% RTP slot, so a 4% house edge. The average value is the bonus minus the average cost of the wagering, a long-run figure that one session will rarely match.

The pattern is simple: at 10x on a 96% slot you keep about 60p of every bonus pound on average; at 35x you lose about 40p per bonus pound on average. A negative figure doesn't mean you will lose that exact amount. It means that across many attempts, chasing a 35x bonus to completion tends to leave you worse off than declining it. You can run other numbers through our wagering calculator.

The break-even multiple: where wagering eats the whole bonus

There is a neat way to see why 35x is so heavy. The average cost of wagering equals bonus × multiple × house edge. It matches the bonus when multiple × house edge = 1, so the break-even multiple is 1 divided by the house edge.

Only on a game returning 98% does 35x sit below break-even, and few slots publish an RTP that high; check each game's information screen, since the RTP must be shown before you play. Many bonus terms also restrict which games count, and table games often contribute less, as our game weighting guide explains. None of this beats the house edge; it only shows how much of the bonus survives on average.

Time and spins: what 35x asks of your evening

UK slots must take at least 2.5 seconds per spin, and autoplay is banned, so every pound of wagering is spun by hand, one spin at a time. Here is the same £50 bonus at 50p a spin.

Longer sessions mean more chances for the balance to hit zero before the target is reached, and more time gambling than you may have planned. Deadlines make it tighter: under current partner terms, 10bet allows 3 days for its 10x and Casumo 7 days. Our pages on Casumo wagering and 10bet wagering set out how each counts progress.

35x on deposit plus bonus: the old double hit

Some older terms applied the multiple to the deposit and the bonus together. On a £50 deposit with a £50 bonus, 35x of £100 meant £3,500 of wagering, about £140 of average cost against a £50 bonus. Gambling Commission guidance now says players must be able to withdraw their own deposit balance at any time and must not face wagering requirements before doing so, which our bonus withdrawal rules page explains.

Under the current code, the cap is written around bonus funds: a customer can't be required to play through bonus funds more than 10 times. If a term seems to apply wagering to your deposit, ask the casino to explain it in writing before you accept.

10x vs 35x on free spins winnings

Wagering can also sit on free spins winnings rather than a matched bonus. Suppose 80 spins at 10p return £8. At 10x, those winnings need £80 of play before they can be withdrawn; at 35x, £280. At a 4% house edge that is about £3.20 of average cost against about £11.20, so the 35x version costs more than the £8 itself on average, while the 10x version leaves about £4.80.

Our partners' spin offers avoid the issue: Coral, Ladbrokes and PlayOJO all carry no wagering on spin winnings. See free spins wagering explained and our answer to whether the 10x cap applies to free spins.

Why UK casinos can't set 35x wagering any more

The Gambling Commission consulted on bonus wagering from November 2023, announced the cap on 26 March 2025, and brought it in on 19 January 2026 after moving the start date from 19 December 2025. It sits in LCCP social responsibility code 5.1.1 (opens in a new tab). The Commission's consultation response (opens in a new tab) records that an outright ban on wagering was considered but not adopted. The same change banned promotions that mix gambling products.

Still seeing 35x wagering? What that tells you

A 35x requirement on a current casino offer aimed at British players is a warning sign. It may come from a site that isn't licensed by the Gambling Commission, which means none of the UK protections apply: no 10x cap, no stake limits, no GAMSTOP participation and no approved dispute service. We never list or link such sites. You can check any operator on the Commission's public register (opens in a new tab), and our guide on how to check a casino licence shows what to look for. Our UK vs non-UK casino bonus page covers the wider differences.

How to check an offer's wagering in five steps

1. Find the multiple in the significant terms shown with the offer, not just in the full T&Cs.
2. Confirm whether it applies to the bonus only, to spin winnings, or (on older or non-UK terms) to deposit plus bonus.
3. Multiply the amount by the multiple to get the total wagering in pounds.
4. Multiply that by the house edge of the game you'd play (100% minus RTP) to estimate the average cost.
5. Compare the deadline with the spins you'd need at your usual stake, and decide whether the bonus is worth taking at all.
