What a wagering requirement is
A wagering requirement is a multiplier on your bonus (or deposit plus bonus) that sets how much you must bet in total before you can withdraw. “40x wagering on a $100 bonus” means $4,000 in cumulative bets — not $4,000 lost, but $4,000 staked — before the bonus and anything won with it becomes real money.
The multiplier exists because a bonus without one is free money: deposit $100, get $100, withdraw $200. Wagering forces the bonus through the house edge enough times that, on average, the casino gets its money back — and usually more. The requirement isn’t a formality on the way to your bonus; it is the price of the bonus, and it’s computable to the dollar.
Every offer in our bonus rankings is scored on exactly this computation, not on headline size.
The core math: turnover × house edge
The expected cost of clearing a wagering requirement is total turnover multiplied by the house edge of the game you clear it on — and that cost routinely exceeds the bonus itself. This one formula is most of what you need.
Take the industry-standard offer: $100 bonus, 40x wagering, cleared on slots with 96% RTP (a 4% house edge):
| Item | Value |
|---|---|
| Bonus | $100 |
| Wagering requirement | 40x bonus |
| Required turnover | 40 × $100 = $4,000 |
| House edge (96% RTP slots) | 4% |
| Expected loss during clearing | $4,000 × 0.04 = $160 |
| Expected net value | $100 − $160 = −$60 |
You were handed $100 and, on average, will feed $160 back through the machines to unlock it. The typical 40x slot bonus has negative expected value — around −$60 on this one. Variance means some players clear with money left; the average player does not. That asymmetry, not generosity, is why the offer exists.
Game weighting: why table games don’t rescue you
Casinos assign each game type a contribution percentage toward wagering, and low house-edge games are weighted down hard — usually to the point where they’re a worse clearing vehicle than slots. A typical weighting table:
| Game type | Contribution to wagering |
|---|---|
| Slots | 100% |
| Table games (blackjack, roulette, baccarat) | 5–10% |
| Video poker | 5–10% |
| Live dealer | 10% (often 0%) |
| Crash / dice originals | 0–5% (frequently excluded) |
The trap is intuitive players walking into it: blackjack has a ~0.5% edge, so clearing there sounds cheap. But at 10% weighting, a $4,000 requirement demands $40,000 in real blackjack bets ($4,000 ÷ 0.10). Expected loss: $40,000 × 0.005 = $200 — more than the $160 the same requirement costs on 4% slots at full weight. At 5% weighting it’s $80,000 staked and $400 expected loss. The weighting table is calibrated so there is no clever exit.
The deposit + bonus trap
“40x (D+B)” is not the same requirement as “40x bonus” — it silently doubles your turnover on a 100% match. Read this line in the terms before anything else.
- 100% match: deposit $100, receive $100 bonus.
- 40x bonus: turnover = 40 × $100 = $4,000. Expected cost at 4%: $160.
- 40x deposit + bonus: turnover = 40 × $200 = $8,000. Expected cost at 4%: $320.
Same headline on the banner, double the price at the till. D+B wagering is the single most common way an average-looking offer becomes a terrible one, and it’s stated in one parenthetical that most players never read.
The clauses that void everything else
Beyond the multiplier, four standard clauses can zero out a bonus’s value on their own. Check each before depositing:
- Max-bet clause. Typically $5 per spin while wagering is active. One $10 bet — even accidental, even losing — lets the casino confiscate the bonus and winnings. This is the most-enforced clause in bonus disputes.
- Max cashout / win cap. Common on no-deposit and free-spin offers: winnings capped at e.g. $100 or 5× the bonus, with the excess removed at withdrawal. A cap converts your right tail — the only reason a negative-EV bonus might be worth gambling on — into the casino’s property. Our no-deposit rankings treat the cap as a first-class term for this reason.
- Expiry window. 7–30 days to finish wagering, or everything tied to the bonus is forfeited. $8,000 of turnover in 7 days is a part-time job.
- Excluded games. Betting on excluded titles while a bonus is active can void it entirely, not merely fail to count.
Sticky vs non-sticky
A non-sticky bonus becomes withdrawable cash once cleared; a sticky bonus never does — only winnings made with it, and the bonus is deducted at cashout. Two offers with identical multipliers can differ enormously here.
Non-sticky (increasingly the norm at better crypto casinos) usually also means your deposit is played first: if you win early on your own money, you can withdraw and simply forfeit the untouched bonus. That optionality has real value. Sticky (“phantom”) bonuses lock your deposit and bonus together until wagering completes, removing the early exit. Between two 35x offers, take the non-sticky one every time.
The real value formula, with three offers
EV ≈ bonus − (total turnover × weight-adjusted house edge). Run it before accepting anything. Three real-shaped offers through the formula, all cleared on slots at 100% weight:
| Offer A | Offer B | Offer C | |
|---|---|---|---|
| Bonus | $50 | $100 | $200 (on $200 deposit) |
| Wagering | 20x bonus | 40x bonus | 45x deposit + bonus |
| Turnover | $1,000 | $4,000 | 45 × $400 = $18,000 |
| Game / edge | 97% RTP slot (3%) | 96% RTP slots (4%) | 96% RTP slots (4%) |
| Expected cost | $1,000 × 0.03 = $30 | $4,000 × 0.04 = $160 | $18,000 × 0.04 = $720 |
| EV | +$20 | −$60 | −$520 |
Offer A — the smallest headline on the page — is the only one worth money: low multiplier, bonus-only wagering, and a high-RTP slot allowed at full weight. Offer C, the banner with the biggest number, is expected to cost you more than half a grand to clear. The pattern generalizes: EV is driven by the multiplier, the D+B flag, and the edge — almost never by the bonus size.
Two refinements to the formula: a win cap truncates your upside, pushing EV further down than the raw number shows; and a short expiry raises the chance you forfeit after paying part of the cost, which also only hurts.
Why wager-free structures win
A dollar of rakeback is worth a dollar; a dollar of 40x bonus is worth roughly negative sixty cents — which is why wager-free structures dominate on real value. Cashback, rakeback, and wager-free spins pay out as withdrawable cash with no turnover attached. There’s no formula to run because there’s no trap to price: 10% weekly cashback on losses is exactly what it says.
This is the logic behind our bonus scoring, and why casinos like Jack.com — 100 wager-free spins and rakeback, no deposit match at all — outscore rivals with 400% headline matches. Smaller number, real money. When comparing a matched bonus against a rakeback deal, convert both to EV and the rakeback usually wins before you finish the arithmetic.
Decision checklist
Sixty seconds with the terms answers whether a bonus is worth taking. Walk the list in order; any early “no” ends the analysis.
- Multiplier and base — is wagering on bonus only, or deposit + bonus? Compute total turnover.
- Expected cost — turnover × house edge of your actual game at its actual weight. Compare against the bonus amount.
- Sticky? — non-sticky with deposit-first play preferred; sticky needs a much better EV to justify.
- Win cap? — any max cashout on a negative-EV bonus is disqualifying.
- Max bet — note the number and stay under it, always.
- Expiry — can you realistically stake the turnover in the window at your normal stakes?
- Compare against wager-free — would this casino’s (or a top-ranked rival’s) rakeback beat this offer’s EV?
Most bonuses fail at step 2. That’s not cynicism — it’s the point of the product. The ones that pass are genuinely worth taking, and now you can tell them apart in a minute.
