Every casino bonus comes with strings attached. The biggest string is the wagering requirement — the number of times you must bet the bonus (or bonus plus deposit) before the casino lets you withdraw. We break down exactly how wagering works, where the traps hide, and how to figure out if a bonus is actually worth your time.

What Wagering Requirements Are

A wagering requirement is a multiplier. It tells you how much money you need to bet — in total — before your bonus balance converts into real, withdrawable cash.

Let's say you deposit €100 and the casino matches it with a €100 bonus at 35x wagering. You multiply €100 by 35. The result: €3,500 in total bets before you can cash out any bonus winnings. Not €3,500 in losses — €3,500 in cumulative wagers. Every spin counts toward the total, whether you win or lose on that spin.

The multiplier varies dramatically across operators. Casumo sets it at 10x. BetMGM uses 15x. Bet365 lands between 25x and 30x. Betsson sits at 35x. Stake applies 40x. Unibet stretches it to 50x on casino bonuses (and up to 99x on certain promotions). JackpotCity ranges from 35x to 50x depending on the offer.

Wagering Basis: Bonus-Only vs Bonus+Deposit

Here's the part most players miss. Two casinos can both advertise "35x wagering" and mean completely different things.

Bonus-only wagering applies the multiplier to just the bonus amount. Deposit €100, receive a €100 bonus at 35x bonus-only — you wager €3,500.

Bonus+deposit wagering applies the multiplier to the bonus AND your deposit combined. Same €100 deposit, same €100 bonus, same 35x multiplier — but now you wager 35 × (€100 + €100) = €7,000. The same number on paper. Double the real cost.

Some operators go further. A handful apply wagering to winnings from free spins rather than the bonus itself. The terms page spells out which basis applies, but most players never check.

1. Read the terms page first. Look for phrasing like "35x the bonus" vs "35x the bonus and deposit" vs "35x the winnings."
2. Convert to bonus-only equivalent. If a casino advertises 20x on bonus+deposit, the real cost equals 40x bonus-only on a 100% match. Always normalize to bonus-only for fair comparison.
3. Check each promotion separately. The welcome bonus, reload offers, and free spins often use different wagering bases at the same casino.

Game Contribution Percentages

Not every game clears wagering at the same rate. Casinos assign contribution percentages by game type. A €1 slot spin typically counts as €1 toward wagering. A €1 blackjack bet might count as €0.10 — or nothing at all.

Standard contribution rates across the industry look like the following:

• Slots: 100% contribution — every euro wagered counts in full
• Table games (blackjack, roulette, baccarat): 5–20% contribution — a €1 bet counts as €0.05 to €0.20
• Live casino: 10–15% contribution — better than virtual table games at some operators, worse at others
• Video poker: 5–10% contribution — among the lowest rates
• Sports bets: 0% contribution — most casinos exclude sportsbook bets entirely

So what does this actually mean for you? Say you're playing blackjack to clear a 35x bonus and the table game contribution is 10%. Your effective wagering jumps from 35x to 350x. On a €100 bonus, you now need €35,000 in blackjack bets instead of €3,500. The bonus becomes practically unclearable at a table game.

Max Bet Restrictions

Most bonuses cap how much you can bet per spin or per round while an active bonus is in play. The standard limit is €5 per spin. Some casinos set it at €6.25 or €7.50, but €5 is the most common.

Here's the catch. Exceeding the max bet — even once, even by accident — can void your bonus and all associated winnings. The casino's system flags bets above the threshold. Some operators issue a warning first. Others confiscate silently and you discover the loss only when you try to withdraw.

A few scenarios that trip players up:

• Feature buys on slots. A feature buy might cost €80 or €200. The casino treats it as a single bet above the max bet limit, even if your base spin was €2.
• Side bets on live tables. Your main bet is €5, but you also placed a €2 side bet. Total: €7. Some casinos count the combined amount.
• Auto-play at changing stakes. You set auto-play at €4, switch to a different tab, and forget about it. Returning to find your balance gone because a game mechanic increased the bet internally.

1. Check the max bet before you spin. The terms page lists it. Bookmark that number.
2. Avoid feature buys entirely while a bonus is active.
3. Disable auto-play when clearing wagering — manual spins keep you in control.

Expiry Windows

Every bonus comes with a clock. Fail to clear the wagering requirement within the expiry window and the casino removes the bonus plus any winnings earned from it.

Expiry windows fall into three brackets:

• 7 days — tight. You need significant daily play sessions to clear anything above 20x. Free spins bonuses often use 7-day windows.
• 30 days — the industry standard. Enough time to clear 35x–40x wagering on a moderate bonus at a comfortable pace.
• 90 days — generous. Operators like Betsson and BetMGM sometimes offer extended windows on larger welcome packages.

On paper, a 30-day window sounds comfortable. In practice, a €200 bonus at 40x wagering means €8,000 in bets over 30 days — roughly €267 per day. At €2 per spin, you need 133 spins per day. Manageable, but it requires daily commitment.

Not a dealbreaker, but worth factoring into your decision. If you play casually — a few sessions per week — look for bonuses with 30-day windows or longer. If you see 7-day expiry combined with 35x+ wagering, skip the bonus entirely.

Win Caps and Max Cashout

Free spins bonuses almost always include a win cap — the maximum amount you can withdraw from your free spins winnings, regardless of how much you actually win.

Picture a scenario. You receive 50 free spins on a popular slot. You hit a great streak and rack up €500 in winnings. But the bonus terms set a win cap of €100. The casino pays you €100 and removes the remaining €400. Gone.

Win caps typically range from €20 to €500 on free spins offers. No-deposit bonuses carry the strictest caps — often €50 to €100. Deposit-linked free spins tend to offer higher caps or, occasionally, no cap at all.

Some casinos express the win cap as a multiplier of the bonus value. "Maximum withdrawal: 10x the bonus." If your no-deposit bonus was €5, the win cap is €50. If it was €10, the cap is €100. Always check for both fixed-amount and multiplier-based caps.

Sticky vs Non-Sticky Bonuses

The terms "sticky" and "non-sticky" describe what happens to the bonus itself after you finish playing.

Non-sticky (forfeit) bonuses let you play with your deposit first. The bonus money sits in a separate balance. If you win enough from your deposit alone, you can withdraw — and the untouched bonus simply disappears. You never needed to wager it because you never used it. The bonus functions as a safety net: if your deposit runs out, the bonus kicks in.

Sticky bonuses blend your deposit and bonus into one balance from the start. You cannot withdraw any amount until you clear the full wagering requirement on the entire balance. There is no option to walk away with deposit winnings while the bonus sits untouched.

Non-sticky bonuses give you more flexibility and lower risk. You can test a casino with your deposit, and if the games or experience disappoint you, just withdraw your remaining deposit without any wagering obligations. Sticky bonuses lock you in.

Most modern European casinos — Casumo, Betsson, LeoVegas — use non-sticky structures for their welcome bonuses. Older offshore operators still lean sticky. Always verify which type you're getting before depositing.

How to Calculate if a Bonus Is Worth Claiming

Every bonus has a mathematical cost. The house edge chips away at your balance with each bet. Over thousands of spins, that edge adds up. You can estimate the expected loss using a straightforward formula:

Expected Loss = Bonus Amount × Wagering Multiplier × House Edge

For a €100 bonus at 35x wagering on slots with an average 3.5% house edge:

Expected Loss = €100 × 35 × 0.035 = €122.50

The expected loss (€122.50) exceeds the bonus value (€100). On average, you lose more from the wagering process than you gain from the bonus. The bonus has negative expected value.

Now compare Casumo's 10x wagering:

Expected Loss = €100 × 10 × 0.035 = €35

The expected loss is €35 against a €100 bonus. You keep roughly €65 in expected value. The bonus is clearly worth claiming.

1. Calculate expected loss first. Multiply the bonus by the wagering multiplier and by the slot house edge (use 3.5% as a default).
2. Compare to the bonus value. If the expected loss is lower than the bonus amount, the bonus has positive expected value.
3. Factor in contributions. If you play anything other than slots, divide the expected loss by the game contribution percentage. Playing at 10% contribution multiplies your expected loss by 10.
4. Check for win caps. A positive-EV bonus with a €50 win cap still limits your upside. Factor the cap into your decision.

Real Wagering Data from 10 Casinos

Here is how wagering stacks up across the casinos we review. We normalize everything to bonus-only equivalent for fair comparison.

• Casumo: 10x bonus-only — the lowest wagering we've found among licensed operators. Expected loss on a €100 bonus: €35. Positive expected value.
• BetMGM: 15x bonus-only — competitive and clearable. Expected loss: €52.50. Still positive EV.
• Bet365: 25x–30x bonus-only — middle of the pack. Expected loss at 30x: €105. Roughly break-even.
• Betsson: 35x bonus-only — at the industry average. Expected loss: €122.50. Marginal negative EV.
• JackpotCity: 35x–50x bonus-only — depends on the promotion. At 50x: expected loss is €175. Clearly negative EV.
• Stake: 40x bonus-only — above average. Expected loss: €140. Negative EV for most players.
• Unibet: 50x bonus+deposit — equivalent to roughly 100x bonus-only on a 100% match. Expected loss: €350 on a €100 bonus. Avoid for bonus clearing.
• LeoVegas: 35x bonus-only — standard terms, but non-sticky structure adds flexibility.
• 888 Casino: 30x bonus-only — reasonable wagering with a decent game selection.
• Betfair: 40x bonus-only — above average, similar profile to Stake.

Bottom line: anything below 25x bonus-only represents genuine value. Between 25x and 35x, the bonus roughly breaks even. Above 35x, the house edge eats most or all of the bonus value during the clearing process.

Practical Checklist: Evaluating Any Casino Bonus

Before you claim any bonus, run through every item on the list below.

1. What is the wagering multiplier? Note the exact number from the terms page — not from the marketing banner.
2. What is the wagering basis? Bonus-only, bonus+deposit, or winnings? Normalize to bonus-only for comparison.
3. What are the game contributions? Confirm slots count at 100%. Check table games and live casino rates. If your preferred games contribute below 20%, the bonus may not suit your play style.
4. What is the max bet? Usually €5. Know the limit before you spin. Avoid feature buys.
5. What is the expiry window? 7 days is tight. 30 days is workable. 90 days is comfortable.
6. Is there a win cap? Free spins and no-deposit bonuses almost always cap your winnings. Calculate whether the cap makes the bonus worthwhile.
7. Is the bonus sticky or non-sticky? Non-sticky gives you more control and lower risk.
8. Run the expected loss formula. Bonus × wagering × 0.035. If the result exceeds the bonus value, the bonus has negative expected value.
9. Check excluded payment methods. Skrill, Neteller, and Paysafecard deposits are often excluded from bonus eligibility.
10. Read the full terms. Every operator buries at least one restriction in the fine print. Spend two minutes reading before you deposit.
