Crash (Stake Original): How It Works & RTP
Crash is a Stake Original with a 99% RTP and a 1% house edge, where a multiplier rises from 1.00x and you cash out before it busts. It is provably fair, so every round can be independently verified.
How a round works
You bet before the round begins. A multiplier then climbs from 1.00x upward. At a random point it “busts” and the round ends. Cash out before the bust and your stake is multiplied by the value at that instant; fail to, and the bet is lost. As with other crash games, the only decision is when to exit, and you can set an auto-cashout to do it for you.
What the 99% RTP means
A 99% RTP corresponds to a 1% house edge, one of the lowest you will encounter. Over a large number of rounds the game is designed to return about 99% of total wagers. That is a long-run average across many players and bets, not a guarantee for your session, which can run well above or below it over short stretches.
The odds of reaching a multiplier
For crash games, the chance of a round reaching multiplier m is approximately RTP divided by m. At Crash’s 99%, that means roughly a 49.5% chance of reaching 2x and about a 9.9% chance of reaching 10x. The table below lays out a few common targets. The pattern is the same in every crash game: the higher you aim, the rarer the outcome.
| Target multiplier | Approx. chance of reaching it (0.99 / m) |
|---|---|
| 2x | ≈ 49.5% |
| 5x | ≈ 19.8% |
| 10x | ≈ 9.9% |
| 50x | ≈ 2.0% |
Provably fair verification
Crash uses the standard Stake Originals provably-fair system: a hashed server seed shown in advance, a client seed you can change, and a nonce that increments with each bet. After revealing the server seed you can recompute any round’s outcome and confirm it was not altered. This gives players a way to check individual results rather than relying solely on external auditing.
How it compares to Aviator
The gameplay mirrors Aviator, but the math is friendlier: Crash’s 99% RTP beats Aviator’s fixed 97%, a meaningful gap over many rounds. Both are provably fair. If you want to compare the two directly, see our Aviator RTP guide; for another low-edge Stake Original, our Plinko RTP guide covers the ball-drop game at the same 99%.

P(reach m) = RTP / mEvery multiplier probability on this page is computed exactly from the crash-curve identity P(reach m) = RTP divided by m. For a 97% RTP build that gives P(2x) = 0.485 and P(100x) = 0.0097. No sampling, no estimation: the identity is exact, and it is why expected value equals RTP at every cash-out target.

Stake publishes its house edge and provably-fair method on its own site, which blocks automated retrieval, so we do not link it as a source. Every figure here is instead re-derivable from the published payout identity, and any finished round can be verified by the player from the seed pair.
