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.

Mines — Rules & Provably Fair
How to play
A grid (5×5, 7×7, or 8×8) hides a chosen number of mines. Click tiles to reveal them — each safe reveal pushes the multiplier higher. Hit a mine and the round ends with the bet lost. Cash out anytime to bank the current multiplier.
Math
For grid size T, mine count M, after revealing k safe tiles:
The 0.99 factor is the 1% house edge. As fewer safe tiles remain, the next reveal pays disproportionately more — the multiplier ramp gets steep near the end.
10th safe reveal = ~6.2×, 20th = ~242×
Provably fair
HMAC stream → Fisher-Yates permutation of positions 0 to T−1. The first M entries in the permutation are the mine locations. Reproducible from the seeds and nonce.
