How it works
A provably fair crash game draws its multiplier so that the chance of reaching x or higher is simply RTP ÷ x. At 97% RTP a 2× target comes in 48.5% of the time and a 10× target 9.7% of the time; the rest of the time the round crashes before you cash out.
Multiply that chance by the payout and the target cancels out: every cash-out point carries the same expected value, −(1 − RTP) of your stake. A higher target buys no edge — it only trades frequent small wins for rare big ones, which is why long losing streaks are normal rather than a sign that a big multiplier is 'due'.

How the Aviator & Crash Game Calculator works
Crash games — Aviator, JetX, Spaceman, Lucky Jet — all pose the same question: will the round reach your multiplier before it crashes? This free crash game calculator answers it exactly, turning any cash-out target into a win probability, an expected value and the odds of the losing streak you should be ready for.
How crash odds are calculated
A provably fair crash game is built so that the chance of a round reaching x or higher is RTP ÷ x. Aviator runs at 97% RTP, so a 1.5× target comes in 64.7% of the time, 2× comes in 48.5%, 5× in 19.4% and 10× in 9.7%. The remaining probability is the round crashing before your auto cash-out fires — including the instant crash at 1.00 that accounts for the missing 3%.
Because the payout is exactly the multiplier you set, the two cancel out: x × (RTP ÷ x) = RTP. Whatever target you pick, you get back about 97 cents per dollar on average. The calculator shows that expected value explicitly, so you can watch it stay flat while you move the target around.
Why no cash-out target beats the house
This is the most misunderstood thing about crash games. A low target feels safe and a high one feels greedy, but both carry the same −3% edge. What actually changes is the shape of the outcome: a 1.2× strategy wins roughly 81% of rounds and bleeds slowly, while a 50× strategy wins under 2% of rounds and spends long stretches with nothing at all. Same expectation, wildly different ride.
It is also why 'predictor' apps cannot work. The multiplier comes from a seed committed before the round begins, so no pattern in past rounds carries information about the next one. Use the streak table here to see how ordinary a ten-loss run really is, and the risk-of-ruin calculator to see what those streaks do to a bankroll.
FAQ
What are the odds of Aviator reaching 2x?expand_more
At 97% RTP the chance of any round reaching 2× or higher is 97 ÷ 2 = 48.5%. A 2× auto cash-out therefore loses slightly more often than it wins.
Does a higher cash-out target make more money?expand_more
No. Expected value is RTP − 1 regardless of the target, because the payout and the probability cancel. A higher target only makes wins rarer and larger.
Do crash predictors work?expand_more
No. The result is fixed by a seed committed before the round starts, so past rounds tell you nothing about the next. Any tool promising predictions is selling you something.
How long can a losing streak last?expand_more
Longer than most players expect. At a 10× target you miss 90.3% of rounds, so twenty misses in a row happen about 13% of the time — the table on this page gives the exact figures.
