Thirteen of the 31 crypto casinos we review do not publish the wagering requirement next to the bonus they are advertising. You have to open the terms and hunt for it. That is the single most useful thing to know about casino bonuses, so this guide starts there and then explains what the number does to your money.
Table of Contents
What the multiplier actually means
A wagering requirement is how much you must stake before bonus money becomes money you can withdraw. It is written as a multiple: 30x, 40x, 45x.
Take a $100 bonus at 40x. That is not $4,000 of your own money — it is $4,000 of turnover, the total of every bet you place until the requirement clears. On a slot with 96% RTP, wagering $4,000 costs you, on average, about $160 in house edge. The bonus is worth $100. The maths is not close.
That is the honest arithmetic behind almost every welcome offer, and it is why “up to $500 free” is a marketing line rather than a gift.
Bonus-only or deposit plus bonus: the clause that doubles it
The multiple alone does not tell you the size of the obligation. What matters as much is what the multiple applies to.
- Bonus only. You deposit $100, get $100 bonus, and 40x applies to the bonus: $4,000 of turnover.
- Deposit plus bonus. Same numbers, but 40x applies to $200: $8,000 of turnover.
Identical headline, double the work. If the terms say “D+B” or “deposit and bonus”, read the multiple as if it were twice as large.
The cost, in one table
All of it fits on one line of arithmetic: turnover × (100% − RTP) = what clearing it costs you on average. For a $100 bonus on a 96% slot:
| Offer | Turnover | Average cost to clear | Bonus worth |
|---|---|---|---|
| 25x, bonus only | $2,500 | $100 | $100 |
| 30x, bonus only | $3,000 | $120 | $100 |
| 40x, bonus only | $4,000 | $160 | $100 |
| 40x, deposit + bonus | $8,000 | $320 | $100 |
| 45x, deposit + bonus | $9,000 | $360 | $100 |
The break-even sits at roughly 25x on bonus only, on a 96% game, before any other clause is applied. Above that line the offer costs more than it gives, on average, and every restriction below makes it worse. That is not a reason never to take a bonus — variance means individual results scatter widely around an average — but it is the number the headline is hiding.
Game weighting: the clause that moves the most money
The multiple is applied to your turnover, but not all turnover counts equally. A typical weighting table looks like this:
| Game type | Typical contribution | $4,000 requirement becomes |
|---|---|---|
| Slots | 100% | $4,000 |
| Video poker | 10% (often excluded) | $40,000 |
| Roulette | 10–20% | $20,000–$40,000 |
| Blackjack | 10% (often excluded) | $40,000 |
| Live dealer | 0–10% | excluded, or $40,000 |
The pattern is not arbitrary: the games weighted at 10% or zero are the ones with the lowest house edge. An operator will happily let you clear a bonus on a 96% slot and will not let you clear it on a 99.54% video poker paytable or on the free odds bet in craps, which costs the house nothing at all. Weighting is how the operator makes sure the requirement is paid in house edge.
Check the weighting before the multiple. A 30x requirement you must clear on table games is worse than a 45x you can clear on slots.
What we found across 31 casinos
We check the operator’s own terms page for every review on this site, not the promotions page, because the promotions page is where the number goes missing. The count as it stands:
- 13 of 31 do not print the wagering requirement beside the bonus. We record that as a drawback in each of those reviews.
- 2 of 31 run no welcome casino bonus at all — Winna and Sportsbet.io. No bonus also means no requirement to clear, which is worth more than it sounds.
- The highest figure we have verified in writing is 40x, at CasinoBit, on a site an independent reviewer already rates 0.9 out of 10.
Keyhouse sits outside this problem by design: it runs no matched-deposit welcome bonus, so there is no wagering requirement attached to your balance at all. Its loyalty tier is tied to the wallet you connect, and because it never holds your funds there is nothing for a bonus condition to lock up.
The clauses that matter more than the multiple
A 30x requirement with hostile small print is worse than a 45x one written straight. Four things to check before the multiple:
Maximum bet while wagering. Usually $5 or less. Go over it once, even by accident, and many operators void the bonus and everything won with it. This is the clause that generates the most complaints.
Game weighting. Covered above, and worth checking first rather than last.
Expiry. Seven days is common, 30 is generous. An unrealistic clock is how a requirement becomes impossible without being unfair on paper. A $4,000 requirement in seven days is $571 of turnover a day.
Maximum cashout. Some bonuses cap what you can withdraw from bonus winnings, often at 5x or 10x the bonus. You can clear the wagering and still lose most of the win to that cap.
How to read an offer in one minute
Open the terms, not the banner. In order:
- Find the multiple.
- Find what it applies to — bonus, or deposit plus bonus.
- Multiply. That is your turnover.
- Check the weighting of the game you actually intend to play, and divide.
- Check the max bet, the expiry and the cashout cap.
If any of the five is missing from the operator’s own page, treat that as the answer: an operator that will not publish its conditions before you deposit is telling you how it behaves after you win.
And check the house edge of what you will be playing while you clear it — the requirement is paid in RTP, which we explain in RTP, payout ratios and variance.
Is a bonus ever worth taking?
Sometimes. A low multiple on bonus-only, with slots at 100% weighting, a sane max bet and 30 days to clear, is a real if modest edge. A high multiple on deposit plus bonus, with a $5 cap and seven days, is a way to keep your deposit in play until it is gone.
There is also a case for taking no bonus at all. Without one, your balance is yours: no maximum bet, no excluded games, no clock, and a withdrawal you can request whenever you like. For anyone who plans to play a little and cash out, that freedom is usually worth more than a matched deposit with 40x attached.
The offer is not the reason to pick a casino. Whether it holds a verifiable licence and pays people who win is. Our crypto casino comparison checks every licence in the regulator’s own register and publishes each operator’s unresolved-complaint count.

Counts verified on 15 August 2026 against the bonus and terms fields we hold for the 31 crypto casinos reviewed on this site. Wagering figures are quoted only where the operator publishes them; where an operator does not, we record the absence rather than estimate a number. Weighting percentages are the industry-typical ranges and vary by operator — always read the terms of the offer in front of you.
