Rocket Multiplier

Crash and instant games, explained with the maths

Crash games explained: multipliers, cash-outs and odds

A crash game is a bet against a random number. A multiplier climbs until it 'crashes'; you must cash out before then to keep your winnings. Here is what is going on under that simple screen.

The core mechanic

Before each round the game draws a crash point, a number such as 1.37x or 8.20x. As the round runs, the displayed multiplier rises toward it. If you cash out before the crash point, you get your bet times the multiplier at that moment; if the round crashes first, you lose the bet. Everything else, whether it is a plane, an astronaut or a rocket, is theme.

The crash point distribution is built so that the probability of reaching multiplier m is about RTP divided by m. That single formula explains the whole genre: low targets are hit often, high targets rarely, and the average return is fixed by the RTP.

Probability of reaching a multiplier

RTP divided by multiplier. 97% is an illustration; 95% is Spaceman's listed figure.
TargetChance at 97% RTP (example)Chance at 95% RTP
1.5x64.7%63.3%
2x48.5%47.5%
5x19.4%19.0%
10x9.7%9.5%
100x0.97%0.95%

What the format gets you to believe

Because you press the button, crash games feel like skill. You can influence variance by choosing a target, but not the expected return: pressing at 2x or at 10x loses the same percentage of your stakes over time. Streaks look meaningful, but each crash point is drawn independently of the last. The history strip beside the multiplier is decoration.

Variants include instant games like Plinko and Mines, step-based games like Chicken Road, and casual formats such as Aviamasters. They share the same principle: a paytable with a built-in margin. Our game guides cover the six we can link to.

JetX is another well-known crash game, from SmartSoft. It is not available at our partner, so it has no page here.

Crash games: questions

What does 'crash' mean?

The point where the multiplier stops and unclaimed bets are lost.

Is the crash point fixed in advance?

It is drawn before or as the round starts, but it is not known to you. Some games let you verify it afterwards.

Do bots or signals work?

No tool can read a random number before it is revealed.

Why do some crash rounds end at 1.00x?

Many designs include a chance of an instant crash. It is part of how the margin is built.
