A wagering requirement is the total you have to bet before bonus money turns into cash you can actually withdraw. It is written as a multiplier, so at a fairly steep 50x a €50 bonus means €2,500 in bets before a single cent becomes yours. Whether that multiplier applies to the bonus alone or to your deposit plus the bonus is the biggest factor in whether an offer is generous or a mirage. Get that one detail wrong and the "free" money is anything but.
What the multiplier is really telling you
The multiplier counts how many times the bonus, or in some cases the bonus plus your deposit, must be turned over in wagers. The little words sitting next to that number change the whole sum.
Take "40x bonus" against "40x bonus and deposit". Deposit €100, collect a €100 bonus, and a bonus-only 40x term asks for €4,000 in bets. The deposit-and-bonus version of the same 40x asks for €8,000. Identical headline, double the slog. So before you judge any offer, work out which base the multiplier attaches to, because a friendly-looking 30x can quietly become harder than a scary 50x once the base shifts under it. Across the Curaçao-licensed casinos I have reviewed over the years, terms tend to cluster somewhere around 40x to 45x on deposit-and-bonus, though it swings widely and the only figure that counts is the one printed in that operator's own rules.
Working out the turnover, step by step
Numbers make this land, so let me run one right through.
You deposit €100 and claim a 100% match. That hands you a €100 bonus and €200 to play with. The terms read 50x on the bonus. That is 50 multiplied by €100, which comes to €2,500 in total bets before the bonus and anything you win from it become withdrawable.
Two and a half thousand euros of wagering off a hundred-euro deposit catches people out every single time. It does not mean you need €2,500 sitting in your account. It means the sum of every stake you place, win or lose, cycled through your balance again and again, has to reach €2,500. On slots returning 96% to the player, the house edge shaves roughly €4 from every €100 wagered on average. Grind the full €2,500 and you are looking at around €100 in expected losses just to clear the offer.
Here is the same maths across a few common terms, so you can see how fast the target climbs.
| Bonus | Multiplier and base | Turnover required | Read on it |
|---|---|---|---|
| €50 | 35x bonus | €1,750 | Reasonable by market standards |
| €100 | 40x bonus | €4,000 | Middle of the pack |
| €100 | 50x bonus | €5,000 | Steep. Needs a genuine win to justify |
| €100 deposit + €100 bonus | 40x deposit and bonus | €8,000 | Same 40x, roughly double the grind |
Game weighting: the trap next to the multiplier
This is the detail that ambushes more players than the multiplier does. Not every game counts fully toward the target.
Slots almost always count in full. Bet €1 on a slot and the whole €1 ticks off your requirement. Table games are where it bites, and the table below shows a typical spread of contribution rates you will find in the small print.
| Game type | Typical weighting | Bets needed to clear €2,500 | What that means for you |
|---|---|---|---|
| Slots | 100% | €2,500 | The fast, standard route to clear a bonus |
| Crash games (Aviator style) | Often 50% or excluded | €5,000+ if counted at all | Check first; many are barred outright |
| Video poker | 10-20% | €12,500-€25,000 | Slow, and rarely worth it for clearing |
| Roulette | 5-10% | €25,000-€50,000 | Frequently capped or void near the edges |
| Blackjack | 5% (often 0%) | €50,000 or never | Low edge, so casinos discount it heavily |
| Live dealer tables | 0-5% | Usually impossible | Commonly excluded from wagering entirely |
Look at what weighting does to blackjack. If it counts 5%, a €1 blackjack bet chips only €0.05 off your target, so you would need €50,000 in blackjack stakes to clear the same requirement a slots player clears with €2,500. That is exactly why bonus-clearing is nearly always a slots job. Tables are not usually banned outright; it is that the arithmetic makes them pointless.
The clauses that quietly cap your winnings
Beyond the multiplier and the weighting sit four smaller rules that decide whether a bonus is worth touching at all. Read these in any terms before you opt in.
- Max bet while wagering. Your stake is capped during play, commonly at €5. Break it once, even by accident on a €10 spin, and the whole bonus plus its winnings can be voided.
- Max cashout. Winnings from the bonus are capped, often at something like 3x or 10x the bonus. Land a big hit and you keep only the capped slice.
- Time limit. The bonus expires, frequently inside 7 to 30 days. Unfinished wagering when the clock runs out means the bonus is simply lost.
- Eligible games. Certain titles are excluded completely. Bets on them count zero, and in the harshest wording they void the offer.
The max-cashout cap is the sneakiest of the four. You could grind the full €2,500, get lucky on a bonus round, and still walk away with only a few times the bonus because the ceiling swallowed the rest. A generous-looking headline sitting on a low cashout limit is worth far less than it pretends.
Why bonuses are often "sticky"
A quick word on jargon that trips people up. A "sticky" bonus is one you cannot withdraw itself. It sticks to your account, and only the winnings above it can ever be cashed out, once wagering is done.
Say you take a €100 sticky bonus and grind up to €400. At withdrawal, the €100 bonus portion is stripped back out and you keep the €300 you built on top. A non-sticky bonus, by contrast, becomes real cash the moment wagering clears. Most large casino welcome offers are sticky, which is one more reason the max-cashout line matters so much.
Daily cashback deals often carry a gentler condition than a match bonus. Some casinos, iWild among them, publish a daily cashback that must be wagered just three times before you can withdraw it, which is a far lighter lift than the 40x-plus you meet on a welcome package. It is a useful reminder that "wagering" is not one fixed number; the multiplier and the base vary enormously from one promotion to the next, even inside a single casino.
The honest downsides of chasing wagering
I will be blunt about where this goes wrong, because the maths has real teeth.
- Treating the multiplier as the whole story. Weighting can multiply the true grind tenfold the instant you drift onto the wrong games.
- Overlooking the max-bet rule. A single oversized spin can wipe out everything you have wagered so far, and support rarely reverses it.
- Ignoring the cashout ceiling. Clearing the rollover counts for nothing if a low cap pockets your winnings first.
- Racing the clock. A 7-day window on a few thousand euros of turnover is genuinely tight, and rushing tempts bigger, riskier bets.
- Chasing losses to "finish". The requirement is a condition, not a debt. Abandoning an unfinished bonus is always allowed, and sometimes it is the smart call.
Read the terms once, slowly, before you tick the box. It is the least glamorous minute in online gambling. It is also the one that most reliably saves money.
Frequently asked questions
What is the way to calculate wagering requirements?
Find the multiplier and its base, then multiply. If the terms say 50x on the bonus and your bonus is €50, that is 50 by €50, so €2,500 in total bets before you can withdraw the bonus or its winnings. If the terms read "50x deposit and bonus", add the deposit to the bonus first, then multiply, which roughly doubles the figure. Always confirm which base the multiplier attaches to before you claim.
Why do table games contribute less to wagering?
Because casinos weight games by house edge. Slots hand the house a bigger long-run margin, so they count 100% toward the requirement. Blackjack and roulette carry a much lower edge, so a player could otherwise clear a bonus on them at little cost to the operator. To stop that, table games are weighted at roughly 5-10%, meaning a €1 bet chips only €0.05 to €0.10 off your target. That gap is why bonus wagering is almost always done on slots.
What counts as a fair wagering requirement?
There is no single number, but a friendlier bonus has a lower multiplier, a bonus-only base rather than deposit-and-bonus, 100% slot weighting, a workable max bet, and either no cashout cap or a high one. Anything from 20x to 35x on the bonus alone is reasonable by market standards, while 50x and up is steep and needs a genuinely good win to justify. Judge the whole set of terms together, never the headline multiplier on its own.
