TILE BY TILE, BANK WHEN NERVOUS
Choose how many mines hide in the grid, then reveal tiles: every clean pick multiplies the pot, any mine zeroes it, and cashout is available between picks. Mine count is your variance dial — more mines, steeper multipliers, shorter runs. The mines calculator gives exact multiplier-versus-probability tables for each configuration, and the mines guide covers sensible cashout ladders.
Rollbit runs the game at its house-standard 1.5% take across all configurations — the compounding multipliers are shaved uniformly, so no grid setup is secretly better priced. Wins cap at $500,000 per bet, and withdrawal timing follows Rollbit’s cashier policy and network confirmations — we have not timed a withdrawal on Rollbit ourselves.

Discipline beats intuition here: pre-commit to a reveal count before the round, because mid-round the sunk multiplier will always argue for one more tile. That argument is exactly what the edge feeds on.
THE GRID WAS SET BEFORE YOU CLICKED
Mine positions derive from the committed server seed and your client seed — laid before your first pick, provably untouched after. Rerun any round through the mines verifier (method notes in verifying mines results). And anyone selling a “mines predictor” is selling fiction — see our predictor scam breakdown.
