What a bonus win cap is

A win cap, sometimes called a maximum win or maximum conversion, limits how much of your bonus winnings can become real, withdrawable cash. For example, an offer might say “maximum winnings from free spins: £100”.

It only applies to winnings from the bonus or spins it’s attached to. It doesn’t limit what you can win when you play with your own deposited money.

Where you’ll find win caps

• No deposit offers: almost always capped, often at £50 or £100.
• Free spins: many deposit and sign-up spins have a cap, including some no-wagering spins.
• Bonus money: some deposit match bonuses cap the amount you can convert to cash, though many don’t.
• Reload and loyalty offers: caps vary from offer to offer.

Worked examples

Example 1: a cap that bites. You get 50 free spins at 10p, worth £5 in total, with a £100 win cap and no wagering. You land a feature and finish with £140 in winnings. The casino removes £40, so £100 is paid as cash.

Example 2: a cap that doesn’t matter. The same 50 spins return £6.20. That’s well under the cap, so you keep the full £6.20. Most of the time, small spin offers finish below their cap.

Example 3: a cap after wagering. A £10 no deposit bonus has 10 times wagering and a £50 cap. You complete the £100 of wagering and finish with £85. The cap applies, so £50 can be withdrawn and £35 is removed.

How a win cap changes an offer’s value

For most players, a cap rarely changes the result, because typical returns on small offers sit well below it. However, part of an offer’s average value comes from rare big wins. A cap cuts those off, so it does lower the true value a little, and a low cap lowers it more.

As a rule of thumb, compare the cap with the offer size. A £100 cap on £5 of spins is 20 times the offer, which leaves room for a decent win. A £20 cap on the same spins is much tighter.

How to spot a win cap before you claim

1. Open the full terms, not just the headline.
2. Search the page for “maximum”, “max win”, “cap” or “conversion”.
3. Check whether the cap applies to winnings, withdrawals or both.
4. Look for a deposit-to-withdraw rule on no deposit offers, too.
