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.

Keno — Rules & Provably Fair
How to play
Pick 1 to 10 numbers from the 1-40 grid. The game draws 10 numbers without replacement. Payout depends on how many of your picks hit, and the risk level you chose.
Risk levels
- Low — small base payouts, frequent small wins, modest top end.
- Medium — balanced. Needs a few hits to break even.
- High — many low/no-pay outcomes, but the top payouts are several hundred times the bet.
All three risk modes target the same ~1% house edge in expectation; they redistribute the variance.
Provably fair
The HMAC stream feeds a Fisher-Yates shuffle over numbers 1-40. The first 10 in the resulting permutation are the draw. Same seeds + nonce always reproduce the same draw.
