Guide

An evening of play has a price — work it out in advance

The expected loss is the product of three numbers: stake size × number of rounds × house edge. It is the average price of a playing session, in the same way a cinema ticket or a dinner has a price. The difference is that the casino does not display it at the till.

Example. A two-euro stake, five hundred spins in an evening, a 96% RTP slot. The turnover is a thousand euros, the house edge 4%, the expected loss forty euros. The same evening in a 99% RTP dice game costs ten. The same time, the same stake, a fourfold difference.

Why this number matters more than the budget. Most players plan the deposit ("I will put in a hundred euros"), not the turnover. But a hundred euros of balance is not a hundred euros of cost — it gets played through repeatedly. If you cycle it ten times, the turnover is a thousand and the cost is four times what your "budget" assumed.

A crypto casino peculiarity. Rounds here are fast: crash and dice run in seconds and in auto mode hundreds of rounds a minute. The number of rounds grows many times faster than a person expects, and with it the turnover. That is exactly why a time limit matters as much as a money limit here.

How to use the result. If the calculated number is larger than the amount whose loss would not bother you, change one of the three inputs: a smaller stake, fewer rounds, or a game with a lower edge. The third is usually the least painful. To set the limits, see the limits guide and the self-assessment — at a foreign casino nobody does it for you.

Frequently asked questions

Will I always lose the expected amount?
No. It is an average across many sessions. A single evening can be considerably better or worse — that is described by volatility.
Does a bonus reduce the expected loss?
Only if the bonus’s value exceeds the cost of the extra turnover the wagering creates. Work that out with the [bonus calculator](/tools/bonus-calculator).
