What “40x wagering” actually means
A wagering requirement is the amount you must wager in total — not lose, not deposit — before the bonus and any winnings from it become withdrawable.
If a €100 welcome bonus has 40× wagering, you must place €4,000 in bets before you can cash out.
Two flavors — read the T&C carefully:
- B (bonus-only) wagering: 40× the bonus amount. €100 bonus → €4,000 turnover.
- D+B (deposit + bonus) wagering: 40× (deposit + bonus). €100 deposit + €100 bonus → €8,000 turnover. Twice as bad.
D+B roughly doubles the true cost. If two bonuses advertise “40x” but one is B and the other D+B, the B version is meaningfully better.
Game contribution — the second hidden variable
Wagering counts differently across game categories:
| Category | Typical contribution |
|---|---|
| Slots | 100% |
| Video poker | 10–25% |
| Table games (blackjack, roulette) | 5–10% |
| Live dealer | 0–5% |
At 10% contribution on blackjack, a €4,000 wagering requirement becomes €40,000 of blackjack turnover — practically impossible with a small bankroll and a max-bet cap. Live-dealer contribution of 0% means live games don’t clear the bonus at all.
Turnover expected loss — the true cost of a bonus
For any game at RTP r, expected loss over turnover T is T × (1 − r).
A €100 bonus with 40× B wager cleared on 96.5% RTP slots:
- Turnover: 40 × €100 = €4,000
- Expected loss: €4,000 × 3.5% = €140
So the €100 bonus is worth, on expected value: +€100 − €140 = −€40. You are paying €40 in expected losses to hunt whatever tail-side outcomes the volatility produces.
That’s why the wagering multiplier dominates everything. Halving the wager (40× → 20×) cuts the expected loss in half and often flips the EV positive.
Max bet during wagering — silent killer #1
Almost every welcome bonus caps your bet during wagering at €5 (sometimes €7 or €10). If you place a bet above this cap even once, the bonus and any winnings from it are voided.
Max bet interacts with your bankroll: if you have €200 total and a €4,000 wagering requirement, you need 800 spins at €5 to clear. At 200 spins/hour that’s four hours of slot play per bonus. Multiply this across a portfolio of bonuses and time-to-clear becomes a real constraint.
Max cashout — silent killer #2
No-deposit bonuses and some crypto bonuses cap the amount you can withdraw from bonus winnings. A “max cashout 3×” cap on a €25 no-deposit bonus means the most you can ever cash out from that bonus is €75, regardless of what you win during wagering.
For welcome bonuses the max cashout usually only applies to no-deposit portions; deposit-match bonuses often say “no max cashout on real-money wins”.
The wager sweet spot
Empirically (see /bonuses live table) the boundary between negative-EV and positive-EV bonuses at 96.5% RTP medium-volatility slots sits at roughly:
- 25×–30× B — usually positive EV.
- 35× B — break-even, sometimes positive with the right game.
- 40× B — usually negative EV, sometimes positive with high-RTP low-vol games.
- 40× D+B or 50× B+ — reliably negative EV; only take them for the entertainment value.
What to look for in the T&C
Before claiming any bonus, we recommend checking:
- Wager multiplier and scope (
BvsD+B). - Max bet during wagering.
- Game contribution table.
- Restricted games (some high-RTP titles are excluded from wagering).
- Bonus expiry (days).
- Max cashout.
- Restricted countries and payment methods (some deposit methods void bonuses — Skrill and Neteller are common exclusions).
If any of these is not disclosed on the operator’s bonus terms page, treat the bonus as untrusted and skip it. Our tracked bonuses have every field populated (see /bonuses).
