Crash on Stake, the reference implementation.
Stake's Crash runs the same win-chance formula as this site's calculator — a 1% house edge, no meaningful multiplier ceiling — with a couple of Stake-specific limits worth knowing before you compare numbers directly.
Effectively uncapped, with real-world limits.
Stake's Crash allows a maximum multiplier of 1,000,000× and a minimum cash-out of 1.01× — a ceiling high enough that it functions as uncapped for practical purposes. Payouts are capped at $200,000 per bet, a liquidity limit rather than a math one.
Place a bet, then the multiplier climbs from 1.00× in real time. Cash out any point before the round's pre-committed crash point and you're paid your bet × the multiplier at that moment; miss the window and you lose the bet entirely. The crash point itself is generated and hashed before the round opens — nothing about it changes once betting closes, the same mechanic the live simulator uses.
You can verify every single crash point yourself.
Three inputs, one hash
A server seed, your client seed, and a nonce that increments per bet run through cryptographic hashing to produce each round's crash point — the same mechanism behind every Stake Original, including Mines and Plinko.
Published before the round
The hashed server seed is shown before betting opens — a fingerprint that locks in one exact value, so the crash point can't be picked in response to how much action is riding on the round.
You reveal it to check
Rotating your seed pair in Settings → Fairness reveals the previous server seed. Re-run the calculation yourself and you get the same crash point Stake displayed.
The 1% figure is the widely-cited convention for Stake's Crash and is what this site's calculator uses. We haven't independently re-derived Stake's exact internal constant round by round — the underlying win-chance formula scales cleanly if Stake ever publishes a different number.
Questions specific to Stake's version.
Does Stake's Crash use the same math as this calculator?
Yes — the same RTP ÷ target win-chance formula, at the widely-cited 1% house edge. Stake adds a practical maximum multiplier (1,000,000×) and a per-bet payout cap ($200,000 cited), but those are liquidity limits, not changes to the underlying odds at any target below them.
What's the minimum cash-out on Stake's Crash?
Cited at 1.01× — you can't lock in a win at exactly 1.00×, since that's also the value used for an instant crash. Anything from 1.01× up is a valid cash-out target.
How is the win chance for a specific target actually calculated?
Every crash game, Stake's included, runs on the same inverse-probability formula.
The formula
- Win chance for target m is RTP ÷ m — the probability the crash point lands at or past m.
- Payout on a win is simply m× the bet — the target multiplier is the payout multiplier.
- Expected value per bet is (RTP − 1) × bet, a constant regardless of which target you pick.
Worked example — 2× target
- Win chance: 0.99 ÷ 2 = 49.50%
- Payout on a win: 2.00× the bet
- Expected value: (0.99 − 1) × bet = −1.00% of the bet, same as any other target
Can I see the crash point before I bet?
No, and that's the point. The crash point is generated and hashed before the round opens — hidden from you but locked in, so it can't be adjusted once betting starts. You verify it was fair afterward using the seed-checking process above.
Is Stake's Crash rigged?
The provably fair system exists specifically so you don't have to take that on trust — every round's crash point is reproducible from the server seed, client seed, and nonce using public hashing math. It doesn't change the built-in 1% edge, which applies whether that round crashes early or late.
Why does my result feel different from the stated 1% edge?
The 1% is a long-run average across thousands of rounds, not a per-session guarantee. A handful of rounds — especially with Martingale-style bet sizing — will always look nothing like the long-run number.
Is there a best cash-out target on Stake?
No — every target carries the same edge, so "best" comes down to the ride you want, not an edge you can find. The full trade-off is broken down on the Crash strategy page.
Do "predictor" tools or timing patterns work on Stake's Crash?
No. The crash point is drawn from a cryptographic hash before the round starts, so a browser extension or "pattern" tool has no data to work from that you don't already have. Clock-based timing theories and color/streak tracking are the same gambler's-fallacy pattern-matching covered on Mines' predictor page — Crash just wears a different multiplier.
