Understanding Wagering Requirements

Updated: June 2026  •  By Jay, BonusBobcat  •  10 min read

A wagering requirement is the number of times you must bet a bonus before the casino will let you withdraw any winnings from it. A 30x wagering requirement on a £50 bonus means you need to stake a total of £1,500 before your balance becomes withdrawable. That’s the whole concept. The reason most players find it confusing is that casinos apply wagering requirements in several different ways, and some of those ways are designed to be nearly impossible to clear.

This guide explains exactly how they work, what the numbers actually mean, and how to identify the bonus terms that will never pay out.

How Wagering Requirements Are Calculated

The basic calculation is: bonus amount × wagering multiplier = total amount you must stake.

Example: You claim a 100% deposit match up to £100. You deposit £100, giving you £100 in bonus funds. The wagering requirement is 30x the bonus. You must stake £100 × 30 = £3,000 before you can withdraw.

However, there are two versions of this calculation, and they produce very different results:

Wagering on the bonus only (more common): If the requirement is 30x the bonus and your bonus is £100, you need to stake £3,000.

Wagering on the bonus plus deposit (more demanding): If the requirement is 30x the bonus + deposit and your deposit was also £100, you need to stake £6,000. This is almost always buried in the small print. A 30x bonus+deposit requirement is roughly equivalent to a 60x bonus-only requirement. Always check which calculation applies.

What Is a “Fair” Wagering Requirement?

There is no universal standard, but here is how the industry generally breaks down:

Under 20x on the bonus — generous. Genuinely clearable with normal play. Our no wagering casino bonuses page covers offers with 0x requirements if you want to skip this entirely.

20x–35x on the bonus — standard. These can be cleared but will require sustained play. Worth checking the game restrictions and time limit before claiming.

35x–50x on the bonus — high. At this level, the expected return on the bonus is significantly reduced. The bonus may not be worth claiming unless you were planning to play that volume anyway.

Over 50x, or any bonus+deposit requirement above 25x — predatory. At this level, the casino is statistically certain to profit from the bonus regardless of game outcomes. Many players will never successfully clear it. This is a red flag.

The Maximum Bet Rule

Almost every casino with wagering requirements also applies a maximum bet restriction during bonus play — typically £5 or £0.50–£1 per spin on slots. This rule is designed to slow down the speed at which you can clear the wagering requirement, and to limit your potential winnings from bonus play.

The maximum bet rule is important for two reasons. First, if you exceed it — even once — the casino is entitled to void your bonus and any winnings derived from it. This is one of the most common reasons players lose bonus winnings they thought they had earned. Second, it means you cannot simply place large bets to clear the requirement quickly. You must play through the full requirement at controlled stakes.

The maximum bet rule is always in the terms and conditions. It is worth checking before you play any game with an active bonus, particularly if you normally play at higher stakes.

Game Contribution Percentages

Not all games count equally toward your wagering requirement. Most casinos publish a contribution table — it’s usually linked from the bonus terms. A typical breakdown looks like this:

This matters in practice: if you play blackjack at 10% contribution and your wagering requirement is £3,000, only £300 of every £1,000 you stake counts. You would need to stake £30,000 at blackjack to clear the same requirement that £3,000 of slots play would clear. Casinos set lower contribution rates on high-RTP games specifically to prevent players from using them to clear bonuses efficiently.

Some casinos exclude specific slot titles entirely during bonus play — often the highest-RTP games from popular providers. This is almost always buried in the game restrictions list attached to the bonus terms.

Time Limits

Most casino bonuses come with an expiry window of 7–30 days. If you haven’t cleared the wagering requirement within that window, the bonus and any associated winnings are forfeited. This is particularly punishing on high-WR bonuses: a 50x requirement on a £100 bonus requires £5,000 of staking within the time limit. At £1 per spin with average spin times, that’s a significant amount of play. Check whether the time limit is realistic for your play style before claiming.

Free Spins Wagering Requirements

Free spins have their own wagering mechanics that differ slightly from bonus fund requirements. When you receive free spins, you play them and generate winnings. It is those winnings — not the value of the spins themselves — that are subject to the wagering requirement.

Example: You receive 50 free spins at £0.10 per spin. Your total winnings from those spins are £4.50. The wagering requirement is 35x the winnings: £4.50 × 35 = £157.50 you must stake before withdrawing.

Most free spins offers also carry a maximum cashout cap on free spin winnings — typically £20–£100, regardless of what you actually win. If your spins generate £250 but the max cashout is £50, you can only ever withdraw £50 from that bonus after clearing the wagering requirement. The max cashout is the single most important number to check on any free spins offer. See our free spins no deposit hub for current offers with verified cashout caps listed.

How to Calculate Whether a Bonus Is Worth Claiming

A rough guide: the higher the bonus RTP and the lower the wagering requirement, the more of the bonus you can expect to retain. A practical formula is:

Expected value = bonus amount × game RTP × (1 ÷ wagering multiplier)

Example: £100 bonus, 96% RTP slots, 30x wagering requirement. Expected value = £100 × 0.96 × (1/30) = £3.20.

That means after clearing the requirement, your expected return from the bonus is roughly £3.20, not £100. That doesn’t mean don’t claim it — it means set your expectations correctly. The bonus extends your play, not your profit margin. At 50x wagering, the same calculation produces £1.92. At 100x, it’s £0.96. The bonus has almost no expected value at that point.

Red Flags to Look for Before Claiming Any Bonus

Wagering requirement above 50x the bonus — at this level, the bonus is almost impossible to clear profitably for the vast majority of players.

“Bonus + deposit” wagering — doubles the effective requirement versus bonus-only wagering. Watch for this in the small print.

Max cashout cap below £50 on free spins — signals the casino knows players occasionally generate large wins from free spins and wants to cap the payout.

Game exclusions or very low contribution rates on all non-slot games — indicates the casino wants you exclusively playing slots, which are typically lower-RTP than table games.

No clearly linked wagering terms — if a casino advertises a bonus but the wagering requirement isn’t clearly stated before you click Claim, that is a compliance failure under UKGC rules and a warning sign about how they handle disputes.

Casinos that use these terms repeatedly appear on our blacklisted casinos list. If a bonus seems too good, check there first.

No Wagering Alternatives

If you’d rather avoid wagering requirements entirely, several operators offer no wagering casino bonuses where winnings are paid in cash with no playthrough conditions. These bonuses are usually smaller in headline value but what you win is genuinely yours. Our no deposit bonus hub and welcome bonus offers section both flag wagering requirements for every listed offer.

Frequently Asked Questions

What does 30x wagering mean?

30x wagering means you must place bets totalling 30 times the bonus amount before you can withdraw any winnings. If your bonus is £50, you must stake £1,500. Whether that’s 30x the bonus only, or 30x the bonus plus your deposit, depends on the specific terms — always check.

Does wagering requirement apply to my own deposit money?

Usually no — the wagering requirement typically applies to the bonus funds only, not your cash deposit. However, some casinos apply the requirement to both the bonus and the deposit combined. This is called a “bonus + deposit” wagering requirement, and it is significantly more demanding. Always check the terms before claiming.

What games clear wagering requirements fastest?

Slots with 100% game contribution clear wagering requirements fastest. High-RTP slots (96%+) minimise your expected losses while playing through the requirement. Table games like blackjack typically contribute 0–10% and are inefficient for clearing wagering requirements despite having higher RTP — because of their low contribution weighting.

What happens if I exceed the maximum bet during bonus play?

Most casinos will void your bonus and any winnings if you exceed the maximum bet rule during bonus play. This typically happens automatically — you will not always receive a warning. The max bet is usually £5 per spin or per hand, but check the specific terms as it varies by operator. If in doubt, bet conservatively while you have an active bonus.

Can I withdraw before meeting the wagering requirement?

Yes, but it comes at a cost. If you withdraw before completing the wagering requirement, the bonus and any bonus-derived winnings are forfeited. Your original cash deposit (if separate from the bonus balance) is usually still withdrawable. Check how your casino separates cash and bonus balances — most display this in the account section.
