A 100-unit bonus at 35× wagering, on a game returning 96%.
| Step | Working | Value |
|---|---|---|
| Bonus | 100 | |
| Wagering multiplier | 35× | |
| Wagering credit required | 100 × 35 | 3,500 |
| Game RTP | 96% | |
| House edge | 100% − 96% | 4% |
| Actual stake, at 100% weighting | 3,500 ÷ 1.00 | 3,500 |
| Expected cost, at 100% weighting | 3,500 × 4% | 140 |
| Actual stake, at 20% weighting | 3,500 ÷ 0.20 | 17,500 |
| Expected cost, at 20% weighting | 17,500 × 4% | 700 |
| Net expected result | 100 − 140 | −40 |
Expected cost 140 against a bonus worth 100, before any other term applies.
Taking the bonus versus not playing at all. Staking 3,500 anyway makes it a partial rebate on a cost already decided; staking 3,500 because the requirement demands it makes it cost more than it gives.
Break-even multiplier = game weighting ÷ house edge.
| Game RTP | House edge | Break-even multiplier | Expected cost at 35× on a 100 bonus |
|---|---|---|---|
| 97% | 3.0% | 33.3× | 105 |
| 96% | 4.0% | 25.0× | 140 |
| 95% | 5.0% | 20.0× | 175 |
| 94% | 6.0% | 16.7× | 210 |
| 92% | 8.0% | 12.5× | 280 |
| 90% | 10.0% | 10.0× | 350 |
Illustrative RTP bands — none belongs to a named game or to any operator on this page. Below break-even is still not a good deal: cashout caps, max-bet limits and expiry all cut what is realisable.
Both columns assume 100% weighting: break-even is 1 ÷ house edge, cost is 100 × 35 × house edge. Below 100%, multiply the break-even by the weighting and divide the cost by it — at 20% the 96% row's 25.0× becomes 5×, and its 140 becomes 700, which is the worked example above.
Break-even multiplier and the turnover a unit of bankroll sustains are one identity seen twice: 1 ÷ 4% is 25, 100 ÷ 4% is 2,500.
A weighting below 100% does not reduce the requirement — it increases the stake.
| Game weighting | Stake needed to earn 3,500 of credit |
|---|---|
| 100% | 3,500 |
| 50% | 7,000 |
| 20% | 17,500 |
| 10% | 35,000 |
| 0% | Never clears |
Stake needed is 3,500 ÷ the weighting. Illustrative: real weightings are set per operator and per game, they change, and none is attributed to any operator here.
The lowest-weighted games often carry the lowest house edge, and it does not cancel. At 10% weighting you stake ten times as much, so the lower-edge game is cheaper only if its edge is under a tenth of the alternative's — against a 4% slot counting in full, that is 0.4%.
A property of the game, over a very large number of rounds. It says nothing about any individual session.
A game returning 96% carries a 4% edge, applied to every unit staked rather than once to your deposit.
Winnings get staked again, so turnover climbs far past the deposit — and turnover is what a wagering requirement is written in.
There is no skill component in any of this, nothing here is a strategy, and no way of playing changes a game's edge.
100 ÷ 4%
100 × 35
2,500 − 3,500
Play a balance to zero and total loss is exactly that balance; expected loss is turnover × house edge, so the turnover it generates is balance ÷ edge. The bonus funds run out a thousand units of turnover short and the rest comes from your own money. Plenty of sessions clear it — the average is what it was priced against.
A ceiling on the stake per spin or hand while bonus funds are in play. Terms commonly treat a breach as forfeiting the bonus and everything won with it. It also sets a floor on how long clearing takes: 3,500 units of requirement under a 5-unit cap is at least 700 bets.
A cap on how much of the winnings can ever be withdrawn — the term that most changes the shape of the outcome. Slot returns are concentrated in rare large multiples and a cap removes precisely those: the best case is bounded, losing the deposit in full is not. Truncated upside, intact downside.
Divide the turnover by the days: 3,500 units over a 7-day window is 500 a day, every day. Unfinished wagering usually means the bonus and its winnings are removed.
Read this before the multiplier itself. Some terms apply it to the bonus alone, some to the deposit plus the bonus. On a matched deposit that doubles the turnover: 35 × 100 is 3,500, but 35 × (100 + 100) is 7,000, and at a 4% house edge the expected cost moves from 140 to 280.
You play your own money first and can withdraw at any point — the bonus is cancelled and goes back. The requirement binds only if your own balance runs out.
The bonus itself can never be withdrawn, only what is left above it and only once the requirement is met — so your deposit sits behind it too. Some terms subtract the bonus at withdrawal.
Neither changes a game's house edge. It changes how much of your money the terms have a claim on, and it is decided when you accept the bonus.
If one of them is hard to find, that is itself information.
A credit with an amount of play attached, and that play is expected to cost more than the credit is worth.
Where an offer requires a deposit you can end with less than you started, and on a negative-expectation product that is the ordinary outcome.
No strategy and no bonus structure turns a house edge positive. We show what a term costs so you can price it yourself.
Casino is regulated separately from betting in many countries, and restricted or prohibited in some where betting is not.
It names who issued the licence — never that the operator may lawfully serve you. Read that on their terms and the regulator's own register.
No licence, no game run, no stakes accepted, no customer funds held.
Availability, licensing, bonuses, payment methods and terms differ by country and change without notice.
GAMSTOP is Great Britain-only, covering only operators licensed by the Great Britain Gambling Commission. An exclusion in one country need not reach an operator licensed in another. If you have self-excluded, this page is not for you. Casino games settle in seconds with no gap between one decision and the next; if that is a problem, the services below are free.
