A wagering requirement (also called a playthrough requirement) is the number of times you must bet the value of a bonus before any winnings it generates can be withdrawn. It's usually shown as a multiplier — bonus amount × wagering multiplier = total amount you need to wager before cashing out — and it's one of the most important terms attached to any casino welcome offer.

What Are Wagering Requirements?
When a casino credits you with bonus funds or free spin winnings, that money usually can't be withdrawn straight away. Instead, it sits in a separate bonus balance until you've staked (wagered) it a set number of times — that's the wagering requirement, often written as a multiplier like "10x" or "35x" next to the offer.
Until the requirement is cleared, bonus funds are there to play with, not to withdraw. Once you've wagered the full amount required, any remaining bonus balance — or winnings generated from it — converts into your real, withdrawable balance, usually still subject to a maximum conversion cap (more on that below).
How Wagering Requirements Work
The maths is simple multiplication: bonus amount × wagering multiplier = total amount you need to wager before you can cash out. Amazon Slots' current welcome offer carries 10x bonus wagering requirements — so if you were credited with, say, £20 in bonus funds, the calculation looks like this:
£20 bonus × 10 = £200 you need to wager before withdrawing

"Wagering £200" doesn't mean losing £200 — it means the total value of the bets you place, win or lose, needs to add up to that figure. Placing £2 spins for 100 spins gets you there just as much as £20 spins for 10 spins; it's the cumulative stake that counts, not the outcome of any individual bet.
Why Wagering Requirements Exist
Wagering requirements exist because a bonus is, functionally, free money handed to a new or returning player. Without any condition attached, someone could claim a bonus, place a single low-risk bet, and withdraw it immediately — which would make welcome offers financially unsustainable for operators to run at all. The multiplier gives the operator a reasonable expectation that the funds will actually be played with before any winnings from them leave the site, which is standard practice across the UK-licensed casino market, not something specific to any one operator.
Terms That Usually Come With Wagering Requirements
The headline multiplier is rarely the only condition. A handful of related terms typically apply alongside it, and every UK-licensed casino's offer should state them clearly next to the offer itself, not just buried in a linked T&Cs page:
- Max bet caps while wagering. Many offers cap the size of any single bet you can place while a wagering requirement is still active — placing a bet over that cap can void the bonus, so it's worth checking before you play.
- Game contribution rates. Not every game counts equally — or at all — toward clearing a wagering requirement. Slots commonly contribute the full amount wagered, while table games, live casino and progressive jackpot slots are frequently excluded or contribute at a reduced rate. Several brands we track explicitly exclude blackjack, roulette and other casino-style games, along with progressive jackpot slots, from bonus wagering entirely — always check which games count before choosing what to play with bonus funds.
- Expiry windows. Bonus balances don't last indefinitely. It's common for unused bonus funds and pending promotions to be removed from an account after a set period of inactivity — for example, several brands we track clear bonus balances after 7 days without a login.
- Max conversion caps. Even after a wagering requirement is fully cleared, there's often a ceiling on how much bonus money can convert into withdrawable funds. A common structure among UK operators caps this at your lifetime deposits, up to a fixed maximum (often £250) — so clearing the wagering requirement doesn't automatically mean the entire bonus balance becomes withdrawable.
What "0x Wagering" Actually Means
Some offers carry no wagering requirement at all — written as "0x wagering." At that end of the spectrum, winnings from the offer are typically paid as cash rather than bonus funds, meaning there's no multiplier to clear before they're withdrawable, though standard account and withdrawal terms still apply.

It's worth understanding 0x wagering as the other end of the same mechanic, not a separate concept: the formula still applies, it's just that the multiplier is zero, so there's nothing to wager before withdrawal. That doesn't automatically make a 0x offer "better" than a 10x one overall — the size of the bonus, the min deposit, and the max conversion cap all factor into the total value of an offer, not the wagering multiplier alone.
Real Wagering Terms at UK Casinos
Rather than quoting industry-wide figures, here's what the wagering terms actually look like across brands we track, checked directly against their published terms:
- Amazon Slots — 10x bonus wagering requirements, with bonus funds converting to real funds up to your lifetime deposits (max £250).
- Pirate Slots — 10x bonus wagering requirements on its Bonus Wheel match offer, same £250 max conversion structure.
- Rainbow Spins — a split structure: 0x wagering on Free Spins winnings, but 10x wagering on separate Bonus Cash.
- Buffalo Spins, Loot Casino and Big Thunder Slots — each currently run a free spins offer with 0x wagering requirements on the winnings those spins generate.
Notice that Rainbow Spins shows both ends of the spectrum within a single welcome offer — free spins winnings arrive with no wagering attached, while separately credited bonus cash carries the standard 10x term. That's a useful reminder to check the wagering condition attached to each specific part of an offer, not just the headline promotion.

How to Check Wagering Terms Before You Claim
- Read the terms shown next to the offer itself, not just a linked T&Cs page — the wagering multiplier, max conversion cap and min deposit should all be visible together.
- Check which games count. If you plan to play anything other than slots with bonus funds, confirm the game's contribution rate first — some games contribute nothing at all.
- Note the expiry window. If you won't be playing regularly, check how long you have before an unused bonus balance is removed.
- Work out the real total. Multiply the bonus amount by the wagering multiplier before deciding whether an offer suits how you plan to play.
Wagering requirements are a standard, clearly disclosed part of how casino bonuses work in the UK market — understanding the multiplier, what counts toward it, and what caps apply afterward means you know exactly what an offer involves before you claim it.
