VICERUN
A neon-soaked 1980s coastal smuggling run. The multiplier climbs as the run pushes further. Cash out before the bust.
One curve. One decision.
Vice Run is a crash game with a loop players read in one second. No paylines, no bonus matrix. A round takes seconds, and the whole game state fits in a single number.
The run loads
Players stake before the run leaves the dock. Every bet locks to the round's committed seed.
The coast opens up
The multiplier rises as the run pushes further. The longer it holds, the bigger the payout on the table.
One tap decides it
Cash out to bank the current multiplier. Wait one beat too long and the run busts to zero.
Split the stake
Up to five cars on the grid and one bet split across them any way the player likes. Every car races the same committed round, and each carries its own hidden crash point.
Numbers go up
From GO every car climbs the same curve, hitting 2× at about three seconds. Cash out any car at any moment, by tap, by key, or by a server-side auto target.
Crashes feed the survivors
When a car wrecks its stake is gone, and every survivor hits nitro: ×1.18 with four cars left, up to ×1.60 for the last one standing.
The bonus stage
A ticket at 25× stake buys a guaranteed bonus run of 2× to 2,000×, and about one bet in two thousand gets pulled in for free. Median run 9.4×.
Check the math yourself.
Every round is committed before it opens and verifiable after it ends. Operators do not have to take our word for it, and neither do their players.
COMMIT
Before a round opens, the server publishes sha256(server_seed). That hash pins the crash point in place before the first bet is taken.
PLAY
The round runs. crash_at derives from HMAC-SHA256(server_seed, client_seed:nonce), so neither side can steer the outcome mid-round.
REVEAL
After the bust, the server reveals server_seed. Anyone can rehash it, recompute crash_at, and confirm both match the record.
