How to play

The heist: place a bet in the 7-second window — two independent bets, A and B, just like two guns in two holsters. Then the burglars break in and haul money bags out of the vault: every bag climbs the multiplier one rung, ×1.05 up to ×385.68 over 30 bags, faster and faster.

Cash out any time from bag 1 — your stake × the current rung. The police can burst in at any moment: bets still in the vault are lost. Survive all 30 bags and the clean getaway pays everyone still inside ×385.68 automatically.

No trap strategies: cash early or ride long — every strategy returns the same honest 96%. A bet placed during a live heist or the police scene is queued for the next round (tap QUEUED to cancel); a bet in the open window can be taken back too (tap IN THE VAULT).

Provably fair

Each round's outcome is locked before betting opens: its SHA-256 commitment is shown on the stage ("fair: …"), and the seed is revealed when the round ends. Hash the seed to check the commitment, then recompute the round yourself: u = int(first 13 hex of HMAC-SHA256(seed, round)) / 2⁵²; the police arrive after N = the deepest bag k with u < 0.96 / M_k. No one — not even the house — can change a round after its hash is published.
