The only bonus maths you need

Turnover required = bonus amount x wagering requirement. Expected cost of that turnover = turnover x house edge. If the expected cost exceeds the bonus, the bonus has negative value unless you would have played that volume anyway. Example: a €200 bonus at 35x requires €7,000 in bets; on a 96% RTP slot that costs roughly €280 in expected losses. The bonus extends your playtime but is not "free money".

Two things flip this maths in your favour: low wagering (bet365 at 20x) and no wagering (PlayOJO). Cashback and rakeback programmes, which pay cash with no conditions, are also straightforwardly positive.

Bonus terms checklist

Wagering multiple: on bonus only, or deposit plus bonus? The latter doubles the requirement. Expiry: 7 days is tight, 30 days is fair, 90 days is generous. Max bet: usually €5; exceeding it can void winnings. Game weighting: slots 100%, tables and live often 10% or 0%. Max cashout: common on no-deposit bonuses. Sticky or non-sticky: non-sticky lets you play real money first and is far better.

Every casino review on this site lists these terms in a standard format so you can compare them quickly. Where terms vary by country we say so; always confirm on the casino site before depositing.

Frequently asked questions

What is the best type of casino bonus?

For most players, no-wagering free spins or cashback offer the best real value because winnings are withdrawable immediately. Among deposit matches, look for wagering of 30x or less and an expiry of at least 30 days.

Can I withdraw a casino bonus?

Not directly. Bonus funds must be wagered the required number of times before winnings become withdrawable. Cashback, rakeback and no-wagering rewards are the exception and are paid as real cash.

Why did my bonus winnings get voided?

The most common causes are exceeding the maximum bet while a bonus is active, playing excluded games, or withdrawing before completing wagering. Read the max bet rule and game contribution table before you start.
