Every crash result is determined by cryptography before the round starts — we physically cannot change it once players start betting.
HMAC-SHA256(serverSeed, gameId:clientSeed) fed into a formula with 3% house edge.const hash = await crypto.subtle.importKey(
'raw', new TextEncoder().encode(serverSeed),
{name:'HMAC',hash:'SHA-256'}, false, ['sign']
).then(k => crypto.subtle.sign('HMAC', k,
new TextEncoder().encode(gameId+':'+clientSeed)));
const h = new DataView(hash).getUint32(0);
const crash = h % 33 === 0 ? 1.0
: Math.max(1.0, Math.floor(2**32 / (h+1) * 100) / 100);
House edge is 3% — roughly 1 in 33 rounds is an instant bust. All other rounds use the formula above. Source code is open for inspection.
A provably fair crash gambling game that only accepts Monero (XMR). A multiplier rises from 1× and can crash at any moment. Cash out before it crashes to win.

3%. This means over many rounds the house expects to keep 3% of all wagered XMR. It is baked into the provably fair crash formula — 1 in 33 rounds is an instant 1× crash (house wins). All other rounds are determined mathematically.
Minimum bet: 0.001 XMR. Maximum bet: 10 XMR.
No. There is no account recovery. Your secret key is the account. We have no way to identify or restore it. Always back it up in a safe place.
Yes — provably so. Every crash result is determined by cryptography before the round starts. You can independently verify any game result. See the Provably Fair section for details.
Monero is the only truly private cryptocurrency. Transactions are untraceable by design. This aligns with our no-KYC, anonymous-first approach.
If you placed a bet and set an auto-cashout, it will trigger automatically. If you did not set auto-cashout and disconnect before cashing out, the round will resolve normally — if the game crashes before you reconnect, you lose your bet.
What we collect
We store: your account UUID (random), your XMR deposit subaddress, your balance, and your bet/transaction history. Nothing else. No name, no email, no IP address, no cookies beyond your session.
What we don't collect
We do not collect your IP address, browser fingerprint, device info, or location. We do not use analytics, tracking pixels, or third-party scripts. We do not run ads.
Monero and privacy
All deposits and withdrawals use Monero (XMR) — a privacy coin with ring signatures and stealth addresses. On-chain transactions are not linkable to your identity or this site by outside observers.
Your secret key
Your secret key is never stored in a recoverable form outside your own device. We cannot see it after it is issued. If you lose it, no one can help you recover your account.
Data retention
Bet history and transaction records are kept indefinitely to support provably fair verification. Account data is deleted if your balance is zero and your account has been inactive for 12 months.
Third parties
We use a Monero remote node to scan the blockchain. This node can see your subaddress and incoming transactions but cannot link them to you personally. We do not share any data with any other third party.
