Crash games: what can be calculated and what is promised

Checked on 14 October 2026 • Reading time: 2 minutes

Crash games look like a decision: a multiplier rises and at some point you press cash out. Mathematically, though, the house edge is fixed beforehand, and no cash-out point moves it.

Crash games: what can be calculated and what is promised

How the edge arises

The distribution of crash points is chosen so that the expected value of every round is below the stake — typically by 1% to 3%. A low cash-out point wins often but little; a high one rarely but much. The expected loss is the same in both cases. What changes is only the variance, that is, how quickly a bankroll swings.

Why doubling after a loss fails

The idea of doubling the stake after every loss breaks in two places: at the table limit and at your own balance. Eight losses in a row at a cash-out of 2.0 are not exotic, and the ninth stake is then 256 units. Such systems trade a high hit rate for a very rare, very large loss — the expected value is unchanged.

What is actually under your control

Three things: the stake per round, the number of rounds, and the point at which you stop. Fixing those beforehand means holding the part of the game that belongs to you — see planning a session. How the same logic looks on slots is in RTP above 97%, and how to check a single round for tampering is in provably fair.

What used to be claimed here

This page carried "500+ hours of crash testing" and "+340% profit with maths, not luck". Both are removed: the tests did not happen, and a positive expected value is unreachable with a fixed house edge. Rakeback only changes the size of the cost, see rakeback, with the arithmetic. On the term: expected value.

Frequently asked questions

Is there a crash system that works?
No. Systems shift variance, not expected value. Doubling after a loss ends at the table limit or at your balance.

Which cash-out point is best?
None, in terms of return. A low point wins often but little, a high one rarely but much — the expected loss per stake is identical.

Were crash games tested here?
No. The 500 hours and +340% profit stated before had no basis and have been removed.
