A €20 no deposit bonus gives you enough to play properly – and enough to make the wagering requirement worth understanding. A few simple calculations tell you what to expect before you spin.

The one formula you need

Amount to wager = bonus × wagering requirement

The requirement for your offer is shown in the bonus terms when the €20 is credited. Here is what different requirements mean for a €20 bonus:

At a typical pace of 8–10 spins a minute, 1,000 spins take around two hours. That matters, because no deposit offers come with short time limits.

How much of the €20 will be left?

Every bet costs you, on average, the slot's house edge – 4% on a 96% RTP game. So:

Expected cost of wagering = total to bet × (100% − RTP)

These are averages. In practice slots swing a lot: one good bonus round can carry you through a 40x requirement, and a cold streak can end a 5x one. But the table shows why the wagering figure is the most important number in any bonus.

Three ways to improve your chances

1. Choose a high RTP. The difference between 94% and 97% doubles the expected cost of wagering or halves it.
2. Use medium volatility. Very volatile slots are more likely to drain a small balance before the end.
3. Keep the stake modest. A smaller stake does not change the expected cost, but it lowers the swings and makes it less likely that you go bust early.

Important: Whatever the stake you choose, it must stay under the maximum bet in the terms. Going over it, even once, can void the bonus.
