Millionaire Crash
Game Mechanics & Rules
Millionaire Crash generates a crash point from a provably fair hash and displays a continuously rising multiplier starting at 1.00x. Players must submit a cash-out instruction before the multiplier reaches the crash point; failure to do so results in a total loss of the bet.
- Enter your bet amount before the round begins.
- Optionally set an auto-cashout target multiplier. If the live multiplier reaches this value, your bet is cashed out automatically.
- The round starts: the multiplier rises from 1.00x at an accelerating rate.
- At any point before the crash, click Cash Out to lock in your current multiplier as your payout.
- If the multiplier crashes before your cash-out - whether manual or auto - you lose your bet.
- The crash point is determined by the SHA-256 hash and is verifiable after each round; review it in the fairness panel.
Bets and Payouts
Crash main bet: your stake plus the cash-out decision. Multiplier grows continuously; crash point is pre-determined by SHA-256. Cash out before the crash to win at the current multiplier. Nine side bets settle on the same crash point, independent of when (or if) you cashed out.

Play Modes
Manual cashout by button. Enable Auto Cashout for a pre-set multiplier. Auto-bet repeats bets for a fixed round count.
Manual
Bet, watch the multiplier climb, click Cash Out. If you wait too long, it crashes and you lose the stake.
Auto
Auto-bet repeats your bet for a set round count. Enable Auto Cashout separately before starting Auto. A Golden Rocket opening the Precision Challenge also stops Auto.
Stop conditions:
- Round count reached.
- Manual Stop.
- Server error.
Replay and Shared Replay
Your own replays
Each completed round joins your history. Click any row for its details, or press Replay to watch it again with the original crash point and cash-out timing.
Shared replays
Every round has a shareable link. Anyone can watch the multiplier climb and see where it crashed.

Replays play back the recorded round exactly as it happened. Balances are not re-applied.
Optimal Strategy & Analysis
The crash point distribution follows P(crash ≥ x) ≈ 0.96/x, where the 0.96 is the 4% house edge, producing a median crash point near 1.9x. About 48% of rounds reach 2x or higher and about 24% reach 4x or higher. No cashout strategy changes the expected value; the edge is constant.
Auto-cashout at a fixed multiplier is the mathematically cleanest strategy. Setting auto-cashout at 2.0x produces a win rate of roughly 48% (accounting for the house edge), a known payout per win, and stable long-run EV. Lower auto-cashout targets increase win frequency but reduce per-win payout proportionally. Higher targets decrease win frequency while increasing per-win payout - the expected value remains constant across all auto-cashout settings.
Martingale systems (doubling after each loss) are commonly applied to Crash and are especially dangerous due to the high house edge and the possibility of extremely low crash points. A crash at 1.01x on a doubled bet produces a total loss at 2x the original stake. The variance of Crash at high cashout targets is sufficient to produce long losing streaks that exhaust any finite bankroll in finite time with probability 1.
At $20 stake, jackpot-only EV is approximately $0.27 per round if you attempt all six stages. This is less than the payout reduction of 10% of the base EV, so this approach trades some expected return for the chance at $1M.
Provably Fair Verification
The crash point is derived from HMAC-SHA256(server_seed, client_seed + ':' + nonce). A house-edge gate on the first 8 hex characters makes about 4% of rounds an instant crash at 1.00x; for the rest, the first 13 hex characters form an integer h, and with e = 2**52 the crash point is floor((0.96 × e) / (e - h), 2), clamped to the 1.00x-1,000,000x range (values below 1.01x floor to 1.00x, so a little under 5% of rounds land at 1.00x in total). This gives the distribution P(crash ≥ x) ≈ 0.96 / x for x above 1. The crash point is deterministic from the seed inputs. The seed hash is committed beforehand; verify after ending and revealing the session.
The server seed hash is committed before each round begins. Players can verify by obtaining the revealed server seed after their session, rehashing it, and confirming the committed hash matches. The crash point computation is then reproducible using the formula above with any standard SHA-256 implementation. WickedBet publishes the exact formula in the fairness documentation for independent verification.
How Millionaire Mode's jackpot trigger works for Crash is shown in the in-game Millionaire Mode panel. The server-seed hash is committed before the round and the server seed revealed at session end, so the crash point and the jackpot trigger are auditable together.
Millionaire Mode Technical Details
Millionaire Mode in Crash is free to enable; there is no separate per-round fee. Each round can trigger a Golden Rocket; the in-game Millionaire Mode panel introduces the bonus for Crash.
While Millionaire Mode is active, standard wins pay at 90% of the off-mode rate. That 10% margin is what funds the jackpot shot on every round; a triggered Golden Rocket follows its own jackpot rules.
A Golden Rocket opens the jackpot condition. The jackpot is a fixed $1,000,000, pre-funded and paid as a single transaction when the condition resolves.
The jackpot does not accumulate between rounds. Every Golden Rocket is a full attempt at the headline figure.
Frequently Asked Questions
What side bets does Millionaire Crash offer and what are their payouts?
Nine side bets are available: Survived 2x, Survived 5x, Survived 10x, Survived 25x, Survived 100x, Flash Crash, Just Made It, Roll the Dice, Moon Shot. Each is a separate wager placed before the round and settles under the conditions shown in the side-bet table.
What is Millionaire Crash and how does it work?
Millionaire Crash is a provably fair multiplier game where a crash point is pre-determined by a SHA-256 hash of the combined server and client seeds. A displayed multiplier rises from 1.00x until it reaches the crash point. Players must submit a cash-out instruction before the crash; success locks in the current multiplier as payout.
How does Millionaire Mode function in Millionaire Crash?
Millionaire Mode is free to enable with no per-round fee. While it is on, standard wins pay at 90% of the off-mode rate; that 10% margin funds the jackpot shot on every round. Each round can trigger a Golden Rocket (the in-game Millionaire Mode panel shows how the trigger works for this game); the $1,000,000 jackpot is pre-funded and paid in full when the condition resolves.
How can I verify Millionaire Crash is provably fair?
The crash point uses HMAC-SHA256(server_seed, client_seed + ':' + nonce): a gate on the first 8 hex characters instant-crashes roughly 4% of rounds at 1.00x, and the rest compute floor((0.96 × e) / (e - h), 2) clamped to the 1.00x-1,000,000x range, where h is the first 13 hex digits of the hash as an integer and e = 2**52 (so a little under 5% of rounds land at 1.00x in total). The server seed hash is committed before each round. End the session to reveal its server seed. Recompute the formula with the revealed seed to verify any historical crash point.
Which cryptocurrencies are accepted for Millionaire Crash?
Deposits are made in crypto, and the cashier lists the coins accepted. You play Millionaire Crash in whichever of your balances you select, and every stake and payout is settled in that currency. Withdrawals return on-chain to a wallet address you nominate at cash-out time, subject to standard network confirmation.
What is the mathematically optimal strategy for Millionaire Crash?
Auto-cashout at any fixed multiplier produces the same expected value per bet. Lower auto-cashout targets increase round frequency and reduce per-round variance. Higher targets produce more variance but the same long-run return. From a pure EV standpoint, the optimal strategy is the one that minimises variance relative to bankroll size, which is a fixed low auto-cashout target.
