How it works

Seed generated

A random 256-bit seed is hashed millions of times with SHA-256, creating a chain of hashes.

Terminal hash published

The final hash in the chain is published before any games begin. This commits us to every future result.

Played in reverse

Games use hashes from the end backwards. SHA-256 is one-way, so future results can't be predicted.

You verify

After each game, the hash is revealed. Check that SHA-256(hash) equals the previous game's hash.

House edge

5% 1 in 20 games instantly crash at 1.00x

The house edge is transparent and built into the crash point formula. It cannot be changed retroactively - each game's hash chain was generated with its divisor locked in.

Crash formula

h = parseInt(hash[0:13], 16)
e = 2^52

if h % divisor == 0 → 1.00x

crash = floor((100*e - h) / (e - h)) / 100
