Wagering requirements: how they really add up
This page lists no offers and no amounts for Woos. It explains how this type of clause works so you can read any operator's terms yourself. Bonus advertising is restricted in many countries, and a bonus is never free money.
A wagering requirement is the betting volume to complete before a bonus, or the winnings made with it, can be withdrawn. It is the clause that decides what any bonus is worth.
The formula
Bets required = multiplier × base ÷ game contribution. The base can be the bonus, bonus plus deposit, or free-spin winnings. Contribution is the share each bet counts for.
| Bonus (example) | Multiplier | Game and contribution | Bets required |
|---|---|---|---|
| 100 | 35× | slots 100% | 3,500 |
| 100 | 35× | tables 10% | 35,000 |
| 100 + 100 deposit | 35× | slots 100% | 7,000 |
Expected loss
Every unit staked carries the house edge. Expected loss = bets required × (1 − theoretical return). On 3,500 at a 96% slot that is 140, more than the 100 bonus. On 35,000 at European roulette (2.70%) it is about 945. That is why high-wagering bonuses have negative expected value, especially for table players.
Variance: why some people make it
Expected loss is an average. Some players complete wagering on a lucky run; many run out of balance first. Stories of those who made it travel; stories of those who did not, do not.
Why live games are nearly excluded
If blackjack counted at 100%, with basic strategy and a house edge under 1% the expected loss on 3,500 would be a few dozen units, and the bonus would have positive value. Operators know this and cut or remove table contributions. It is a useful signal: a bonus that looks good for your favourite game is almost always excluded for that game.
How to use this page
Before accepting any bonus, run the numbers from the terms: multiplier, base, contribution of the game you actually play, theoretical return. If the expected loss exceeds the bonus, the bonus costs you. Other clauses are under bonus terms.
A quick self-check
Write down four numbers before accepting any offer: bonus amount, multiplier, base and the contribution of your main game. Multiply and divide as in the formula. If the bets required are more than you would normally stake in a month, the bonus will change how you play, and probably not for the better. Declining is a valid result of the calculation, not a missed opportunity.
