Stake Crash is the in-house crash game on Stake.com: one bet per round, a multiplier that climbs in real time, and a 99% RTP that makes it one of the cheapest crash games to play anywhere.
The 30-second version
Stake Crash is a Stake Original built in-house, exclusive to Stake.com and the separate Stake.us social version, with a 99% RTP and a 1% house edge. It is provably fair, but it uses a pre-committed hash chain salted with a public Bitcoin block hash, not the per-player seed model most write-ups assume, and it runs on a Curacao licence with no independent lab audit.

🏢 Who makes Stake Crash
Stake Crash is a Stake Original, meaning Stake builds and runs it in-house through its game-development arm rather than licensing it from a third party. That is why you cannot play it anywhere except Stake’s own properties: unlike Aviator or JetX, it is not sold to other casinos.
Stake itself was founded in 2017 by Ed Craven and Bijan Tehrani, two Melbourne entrepreneurs who had earlier built Primedice and the Easygo studio. The crash game dates from Stake’s early years, and one crash-specialist source says it first launched under the name Chartbet before being renamed. Treat the original name as a single-sourced detail rather than a confirmed fact.
Primedice
The founders build an early crypto dice game, cutting their teeth on provably fair mechanics.
Stake.com launches
Stake opens as a crypto-first casino and grows into the largest crypto-backed online gambling group.
Crash arrives
Crash becomes one of Stake’s early originals, reportedly first named Chartbet, at the 1% edge the genre’s pioneer Bustabit had set in 2014.
⚡ How Stake Crash works
The loop is pure crash, deliberately stripped of any theme or gimmick. There is one bet box and one cash-out box, and every active player shares the same round and the same crash point.
The 5-second window
After each round there is roughly a five-second window to set your stake and your optional cash-out target and place a single bet.
The multiplier climbs
A single shared multiplier rises from 1.00x. A live “profit on win” figure shows what you would collect at the current point.
Cash out
Collect manually at any time, or let the “cashout at” target collect for you. The minimum target is 1.01x.
The crash
The round ends at its sealed crash point. Anyone who has not collected loses that bet, and the next window opens.
🔍 Worth noting: it is a single bet, not dual
Stake’s page mentions “two types of betting”, but that means manual mode versus auto mode, not two simultaneous bet panels. Stake Crash is a single bet per round, unlike Aviator’s two parallel panels.
Auto mode is where the system staking happens. It supports a set number of bets, a percentage increase or decrease after a win or loss, and stop-on-profit or stop-on-loss limits, which is what lets people run progressions like Martingale without clicking. Stake.com also has no demo mode for Crash: the free-play impression comes from the separate Stake.us social version, which uses virtual currency and is a different product.
📊 RTP and house edge
Stake Crash runs a 99% RTP and a 1% house edge, taken straight from Stake’s own documentation, and it is exactly 1.00%, not a rounded approximation. Because it is a house original that Stake builds and runs, the edge is a fixed platform parameter rather than a setting an operator can dial down, which is a real difference from configurable third-party titles.
The edge is built into the multiplier conversion rather than charged as a separate rake. Every potential crash point is scaled by 0.99, which pushes roughly one round in a hundred below 1.00x, where it shows up as an instant crash that nobody can cash out. Two framings, one mechanism.
📖 Definition
A 99% RTP means that for every $100 wagered in aggregate the game returns about $99 and keeps about $1. That 1% is the house edge, and it is the lowest tier in crash gaming, shared with Bustabit and BC.Game Crash.
You may see two outlier claims worth dismissing. One review argues the “realistic” RTP is about 97% because the rare million-times win is baked into the headline figure: that is variance commentary, not a different edge. A separate comparison table lists Stake at 4%, which contradicts Stake’s own documentation and every other source and is simply an error.
“The cheapest crash game to play is also one of the hardest to hold to account.”
⚙️ Features
Stake Crash is deliberately minimalist, so its features are about pace and social play rather than visual extras.
🔢 Multiplier distribution and the 1,000,000x cap
At a 99% RTP the chance of any round reaching a given multiplier is 0.99 divided by that multiplier, and the expected return is the same $0.99 per $1 at every target. The lower edge simply means you keep more of your stake on average than at a 97% game, not that any target wins.
The multiplier is capped at 1,000,000x. The underlying formula could in principle produce a larger value when the random input is near zero, but the game truncates at the cap. Your actual win is your stake times the crash point, bounded by both the 1,000,000x cap and a per-currency maximum-profit limit, whichever binds first. Those per-currency limits, and the minimum and maximum stakes, vary across Stake’s twenty-plus cryptocurrencies and its fiat play currencies, so check them live for the currency you use.
The bottom line: a 1% edge over 1,000 rounds at $1 costs you about $10 on average, against roughly $30 at a 97% game. The maths is genuinely better for the player. The full expected-value proof lives in our crash gambling maths guide.
🛡️ Is Stake Crash fair?
Stake Crash is provably fair, but it does not use the per-player seed model that most third-party “Stake Crash verifiers” assume. This is the single most-confused point about the game, and getting it right matters.
Because Crash is a real-time multiplayer game with one shared crash point per round, the result cannot depend on any individual player’s client seed, since different players would then compute different outcomes. So Stake uses a different architecture for Crash than for its single-player originals like Dice, Limbo and Mines.
A hash chain is pre-committed
Before any rounds run, Stake generates a chain of around ten million server-seed hashes, each the SHA-256 of the next, so the whole future sequence is locked in and cannot be re-ordered.
A public Bitcoin block salts it
The chain is combined with a future Bitcoin block hash, announced before it was mined, so Stake could not have known the results when it built the chain. This is the unpredictable input nobody controls.
Each round is derived
The round’s chain hash is combined with the Bitcoin block salt via HMAC-SHA256, turned into a number, and converted to the crash point.
You verify against the chain
Hash a completed round forward and confirm it produces the previous round’s hash, proving the round was genuinely in the committed chain, then re-apply the salt and formula to confirm the multiplier.
🔍 Worth noting
If a verifier or guide tells you Crash uses a server seed plus your own client seed and a nonce, it is describing the wrong model. That is how Stake’s single-player games work, not the multiplayer Crash, which uses the hash chain plus Bitcoin block salt above. The generic mechanics are covered in our provably fair explainer.

🔍 The house-original trade-off
A house original is a game the casino builds and runs itself, exclusive to its platform, rather than a third-party title certified by an external lab and licensed to many casinos. That structure is exactly what gives Stake Crash its low edge, and also what creates its accountability gap.
What you gain is real: the 1% edge is the cheapest tier in crash gaming, and per-round provable fairness lets you check every result yourself rather than trust a once-a-year audit. What you give up is the rest of the accountability stack.
⚠️ Important
There is no independent RNG or lab certificate, no UK or Malta oversight, and the same company owns the game, the algorithm, the chain seeding and your balance. Provable fairness proves a round was not tampered with. It does not guarantee withdrawals, solvency or fair terms, and it does not stop a game running a high edge in the first place.
Stake Crash sits in the low-edge tier alongside Bustabit, the 2014 game that invented the genre and set the 1% standard, and BC.Game Crash, which shares the same maths but adds extra modes. You can see where it ranks against the rest of the field, and how the regulation-versus-edge trade-off plays out, in our roundup of low house edge crash games.
🏆 Availability and how it compares
Stake.com is owned and operated by Medium Rare N.V. and runs on a direct Curacao Gaming Authority licence, number OGL/2024/1451/0918, under the reformed LOK regime that replaced the old sub-licence system in 2024 and 2025. If you see a source describing Stake as licensed under Antillephone, that is stale, pre-reform information.
Registration is blocked from the United States, the United Kingdom and Australia, among others. Stake briefly operated in the UK from December 2021 through a partner that held the UK licence, but that arrangement has since ceased, so Stake holds no UK licence today. In the US, the separate Stake.us social-sweepstakes site offers Crash on free virtual currency and is legally distinct from the real-money game.
Against the mainstream third-party titles, Stake Crash is three times cheaper per unit wagered than the 3% Aviator default, with a far higher multiplier cap but a single bet and no demo. The full head-to-head, including which suits which kind of player, is in our Aviator vs Stake Crash comparison. Where Stake Crash wins is the maths; where it loses is everything the maths does not cover.
💡 Common mistakes to avoid
The 99% number tempts people into believing the game can be beaten. It cannot.
- Thinking 99% means you win. A 1% edge is still an edge. Over enough rounds you lose on average, just more slowly than at a 97% game.
- Running Martingale on auto. The auto staking tools make progressions easy, but no staking system beats the edge, and the per-currency cap will stop a doubling run before recovery.
- Confusing provably fair with safe. The maths is honest per round, but there is no lab audit and no UK or Malta protection behind your balance.
- Reading the history strip. Each round is independent. A streak of low crashes does not make a high one more likely.
The high speed and the auto-staking tools that make Stake Crash efficient also make it easy to lose track of how much you are wagering. We cover the research on crash-game harm, the risk factors and what to watch for in a dedicated guide: crash gambling and player harm.
❓ Frequently asked questions
What is Stake Crash’s RTP?
99%, which is a 1% house edge, taken from Stake’s own documentation. Because it is a house original, that edge is fixed rather than operator-configurable.
Can I play Stake Crash anywhere other than Stake?
No. It is a Stake Original built in-house and is not licensed to other casinos. You can only play it on Stake.com, or the separate free-to-play Stake.us in the US.
How does Stake Crash provably fair work?
It uses a pre-committed chain of around ten million linked SHA-256 hashes, salted with a public future Bitcoin block hash, not the per-player client-seed model used by Stake’s single-player games. Many third-party verifiers get this wrong.
Is there a demo mode for Stake Crash?
No. Stake’s own blog confirms there is no demo mode for Crash on Stake.com. The free-play version is the separate Stake.us social site, which uses virtual currency.
What is the maximum win on Stake Crash?
The multiplier is capped at 1,000,000x, and your win is your stake times the crash point, limited by both that cap and a per-currency maximum-profit limit. The exact figures vary by currency.
Can I play Stake Crash in the UK?
No. The United Kingdom is a blocked market. Stake briefly operated in the UK in 2021 through a licensed partner, but that has ceased and Stake holds no UK licence now.
