No real money. No signup. No risk.
Your balance lives in this browser only via localStorage — it isn’t real and isn’t worth anything. Reset it any time from the controls panel. Every bet still uses real provably-fair machinery (HMAC-SHA256), so you can verify outcomes the same way you would on Stake, Shuffle or any of the other casinos WinLogger tracks. Click Provably Fair in the controls to inspect, rotate or audit your seeds.
Crash — Rules & Provably Fair
How to play
The multiplier starts at 1.00× and climbs over time. At some point the round crashes. Cash out before the crash to win bet × cashout multiplier. Wait too long and the bet is lost.
You can set an auto-cashout target before the round starts — the system cashes you out automatically the moment the multiplier crosses it.
Math
The crash point is decided up front from a uniform float f ∈ [0, 1):
else → floor(99 / (1 − f)) / 100
Probability of cashing out successfully at multiplier M is roughly 0.99 / M. Long pulls are exponentially rare: 10× survives ~9.9% of rounds, 100× survives ~0.99%.
Provably fair
HMAC-SHA256(server_seed, client_seed:nonce) → 8-byte slice → uniform float f → crash point. Identical seeds and nonce always produce the same crash.
