Crash games: how they work and the odds of each multiplier

In a crash game a multiplier climbs from ×1.00 until it “crashes” at a random point; stop before that and you get the chips at that multiplier, but if the round crashes before your stop, the stake is lost. On IS Casino the chance of a round reaching ×x is exactly RTP ÷ x — at 96% RTP, 48% of rounds reach ×2.

How a round works

  1. During the entry phase you choose your stake in virtual chips and, optionally, an automatic stop.
  2. The round starts: the multiplier climbs in real time, the same for everyone in the room.
  3. You stop manually at any moment, or the automatic stop does it for you.
  4. The crash point was fixed before the round; its hash was published and the key is revealed at the end.

The formula

Crash point = floor(100 × RTP ÷ (1 − r)) ÷ 100, where r is a verifiable random number between 0 and 1, capped at ×1,000. That gives the core property: the probability of the round reaching ×x is RTP ÷ x, for any x. Since stopping at x returns x × (RTP ÷ x) = RTP, every stop has the same 96% RTP.

×109.60%96%
×501.92%96%
×1000.960%96%
×1,0000.096%96%

About 5% of rounds crash before ×1.01 (1 − 0.96 ÷ 1.01 = 4.95%).

What this means in practice

  • There is no “best” target: ×1.5 and ×50 have the same RTP; only the volatility changes.
  • Previous rounds do not matter: every point comes from a new seed. A run of low crashes does not make a high one more likely.
  • The automatic stop is exact: it uses the target multiplier, regardless of your connection speed.
  • Verified: in a 10-million-round simulation per game, every stop from ×1.01 to ×1,000 fell inside the 99.9% interval around 96%.

Lambo Soon, Pilot and Limbo

Lambo Soon (a car) and Pilot (a plane) are shared crash games: everyone plays the same round. Limbo is the instant, individual version: you pick the target, the result comes at once (RTP ÷ (1 − r)) and the chance follows the same formula, at 97% RTP with a maximum target of ×1,000,000.
