A wagering requirement is the amount you have to bet before bonus money becomes cash you can withdraw. It is written as a multiplier. At a steep 40x, a $100 bonus asks for $4,000 in bets before a single dollar is yours to keep. The part most players skip is what that multiplier attaches to and which games count toward it, and that is where the real cost hides.
What “40x” is really telling you
The number tells you how many times the bonus, or in some terms the bonus plus your deposit, has to cycle through wagers. The small words next to it decide the whole sum.
“40x bonus” and “40x bonus and deposit” are not the same animal. Deposit $100, take a $100 bonus, and a bonus-only 40x term asks for $4,000 in bets. A deposit-and-bonus 40x term on the same offer asks for $8,000. Same headline, double the grind. So before I judge any offer, I work out which base the multiplier sits on, because a mild-looking 30x can quietly beat a scary 50x once the base shifts underneath it.
Two crypto-casino paths I have looked at recently used 40x on the deposit plus bonus, which is the tougher of the two bases. That is common, not a scandal, but it changes the arithmetic a lot.
Where do you actually see the multiplier?
It lives in the bonus terms, not the banner. The banner shows you the match. The turnover requirement is one scroll down, usually beside the words “wagering” or “rollover.”
Read that line before you opt in, not after. Once you deposit into a locked bonus, the terms are already binding.
Wager-locked vs no-wager-lock bonuses
This is the single most useful distinction in the whole topic, and it decides how much freedom you have with your own money.
A wager-locked bonus holds the money hostage. You cannot withdraw until you have met the full multiplier on the whole balance, and if you cash out early the bonus and its winnings are stripped. A no-wager-lock bonus works the opposite way: the bonus converts to real, withdrawable cash gradually as you play, in small slices, so there is no all-or-nothing wall at the end.
Rainbet’s promotions page is a clean real-world illustration of both, and I will use it purely as a teaching example (their exact terms rotate, so check the live page and our breakdown of Rainbet’s two welcome paths for current specifics). One path is a classic 40x wager-locked match. The other has no 40x lock at all: the bonus unlocks per bet using a small formula, Wager Amount times 1% times 20%, and whatever unlocks is yours to withdraw.
Run that formula and you see the trade. On the no-lock path, a $10 bet unlocks 10 times 0.01 times 0.20, which is $0.02 of the bonus, released to cash immediately. It is slow, but it is real money the whole way, with no risk of losing an almost-cleared bonus on one bad session. The locked 40x path can be worth more if you clear it, and worth nothing if you do not. Which suits you depends on whether you would rather have certainty or upside.
Game weighting: the trap beside the multiplier
Not every game counts fully. This ambushes more players than the multiplier does.
Slots almost always count 100%, so a $1 slot bet ticks a full $1 off your target. Table games are where it bites. The table below shows the contribution rates you typically find in the fine print, and what each does to a $4,000 target from a 40x term on a $100 bonus.
| Game type | Typical weighting | Bets needed to clear $4,000 | What it means for you |
|---|---|---|---|
| Slots | 100% | $4,000 | The standard, fastest route to clear |
| Crash / originals | Often 50% or excluded | $8,000+ if counted at all | Check first; many are barred while a bonus is live |
| Video poker | 10-20% | $20,000-$40,000 | Slow; rarely worth using to clear |
| Roulette | 5-10% | $40,000-$80,000 | Often capped or void near even-money bets |
| Blackjack | 5% (sometimes 0%) | $80,000 or never | Low house edge, so heavily discounted |
| Live dealer tables | 0-5% | Usually impractical | Commonly excluded from wagering entirely |
Look at what that does to blackjack. At 5% weighting, a $1 blackjack bet chips just $0.05 off the target, so you would need $80,000 in blackjack stakes to clear what a slots player clears with $4,000. That is why bonus-clearing is nearly always a slots job. The tables are not banned. The math just makes them pointless.
How to compute what you must bet
Three steps, and I will run one straight through. Find the multiplier and its base, plug in your numbers, then divide by the weighting of whatever you will actually play.
Say you deposit $100 and claim a 100% match with 40x on the bonus. That is 40 times $100, so $4,000 in total bets before the bonus and its winnings turn withdrawable. If the term instead read 40x on deposit plus bonus, you would add the $100 deposit to the $100 bonus first, then multiply, landing at $8,000.
The next table shows the same $100 bonus at three common multipliers, on the bonus-only base, cleared on 100% slots. It is worth memorizing the shape of these numbers.
| Multiplier | $100 bonus | $50 bonus | $200 bonus |
|---|---|---|---|
| 30x | $3,000 | $1,500 | $6,000 |
| 40x | $4,000 | $2,000 | $8,000 |
| 50x | $5,000 | $2,500 | $10,000 |
None of these is money you need in your account. It is the sum of every stake you place, win or lose, cycled through your balance over and over until it reaches the total. On slots returning around 96% to the player, the house edge takes roughly $4 of every $100 wagered, so grinding $4,000 costs you about $160 in expected losses just to clear the offer. That expected cost is the figure that decides whether a bonus is worth touching.
Max-bet caps while a bonus is live
Almost every locked bonus caps your stake while you clear it, and this is the rule that voids more bonuses than any other.
The cap is sometimes a flat dollar figure and sometimes a percentage of your deposit. Rainbet’s locked welcome path, for instance, sets max bet at 2% of the deposit. On a $100 deposit that is a $2 cap. Place one $10 spin out of habit and the bonus plus everything you wagered can be voided, and support rarely reverses it. I check the cap and set my stake below it before the first spin, every time.
RTP-exclusion clauses on high-return slots
Some terms bar the very slots you would most want to play. The clause usually reads that slots above a set RTP do not count, or cannot be played, while a bonus is active.
Rainbet’s welcome terms exclude slots rated above 97.4% RTP during wagering. The logic is simple: a higher-RTP game returns more to the player, so it is cheaper to clear a bonus on, and the operator would rather you did not. Read the excluded-games list and the RTP ceiling together. A bonus that bars every high-return title is more expensive to clear than the multiplier alone suggests, because you are pushed onto lower-RTP games where the house edge grinds you harder.
Sticky vs non-sticky bonuses
One more piece of jargon. A “sticky” bonus is one you can never withdraw itself; it sticks to your account, and only winnings above it can ever be cashed out once wagering is done.
Take a $100 sticky bonus and grind up to $400. At withdrawal, the $100 bonus is pulled back out and you keep the $300 you built on top. A non-sticky bonus becomes real cash the moment wagering clears. Most large welcome matches are sticky, which is one more reason to check whether any cashout ceiling sits on top of the offer.
The honest downsides of chasing wagering
I will be blunt, because the math has teeth. Bonus-clearing is usually a slow grind with a negative expected value, and the terms are written to favour the house.
We do not recommend accepting any wager-locked bonus above 40x if you value flexibility over a shot at a bigger cleared balance. Above that line, on a deposit-plus-bonus base, the expected cost to clear rarely justifies the reward, and a no-wager-lock path that releases cash as you play is the safer pick for most casual players.
- Treating the multiplier as the whole story. Weighting and RTP exclusions can multiply the true grind several times over the instant you drift onto the wrong games.
- Overlooking the max-bet cap. One oversized stake can wipe every dollar you have wagered so far.
- Ignoring a cashout ceiling. Clearing the rollover counts for little if a low cap pockets most of your winnings.
- Racing the clock. A short expiry window on a few thousand dollars of turnover is genuinely tight and tempts riskier bets.
- Chasing losses to “finish.” The requirement is a condition, not a debt. Abandoning an unfinished bonus is always allowed and often the smart call.
Read the terms once, slowly, before you tick the box. Note the multiplier and its base, the weighting, the max bet, the RTP exclusion, and any cashout cap. That minute is the least glamorous in online gambling and the one that most reliably saves you money. If you would rather skip the grind entirely, a rewards model that pays back a slice of every bet, like how Rainbet’s rakeback and reload stack works, carries no rollover wall at all.
Frequently asked questions
How do I calculate a wagering requirement?
Find the multiplier and its base, then multiply. At 40x on a $100 bonus, that is 40 times $100, so $4,000 in total bets before you can withdraw. If the term reads “40x deposit and bonus,” add the deposit to the bonus first, then multiply, which roughly doubles the total.
What is the difference between a wager-locked and no-wager-lock bonus?
A wager-locked bonus cannot be withdrawn until you meet the full multiplier, and cashing out early strips it. A no-wager-lock bonus converts to withdrawable cash gradually as you bet, in small slices, so there is no all-or-nothing wall at the end.
Why do table games contribute less to wagering?
Casinos weight games by house edge. Slots carry a bigger long-run margin, so they count 100%. Blackjack and roulette have a low edge, so a player could otherwise clear cheaply; to prevent that, tables are weighted near 5-10%, meaning a $1 bet chips only a few cents off the target.
What does an RTP-exclusion clause do?
It bars high-return slots, often those rated above a set RTP such as 97.4%, from counting while a bonus is active. High-RTP games return more to the player and are cheaper to clear on, so operators exclude them and push you onto lower-return titles.
What is a max-bet cap and why does it matter?
It limits your stake while a bonus is live, sometimes a flat figure, sometimes a percentage like 2% of your deposit. Break it, even once by accident, and the bonus plus everything you have wagered can be voided, so set your stake below the cap first.
What counts as a fair wagering requirement?
There is no single number, but friendlier terms use a lower multiplier, a bonus-only base, 100% slot weighting, a workable max bet, and no restrictive cashout cap. Roughly 20x to 35x on the bonus alone is reasonable; 50x and up is steep and needs a genuine win to justify.
Do I lose real deposit money to a wagering requirement?
No, not directly, but you lose expected value grinding through it. On 96% slots, clearing $4,000 of turnover costs about $160 in average losses. A steeper multiplier or a low-RTP-only rule raises that expected cost further.
How did we test these figures?
I read the live bonus terms on several crypto-casino promotions pages, ran the turnover math for each multiplier and base, and cross-checked the weighting and RTP-exclusion rules against the operators’ own fine print rather than the banner copy.
