Choose your stake and 1, 3, 5, 7 or 10 mines. Start spends your virtual stake once. All mines are placed before you pick a tile. Safe picks reveal treasure and extend your trail. A mine ends the round with no return. Cash out after any safe pick; finding every safe tile secures the treasure automatically.

With m mines and k safe picks, survival probability is C(25−m,k) / C(25,k). The multiplier is 0.97 divided by that probability: one 3% demo edge, not 3% per pick. Multipliers are floored to six decimals, then returns to the smallest credit unit. The large multiplier label is floored to two decimals; the cashout amount uses all six. Return includes your stake. No certification or provably-fair claim.

Local demo only. Reloading or leaving during an active round keeps the debited stake spent. An unfinished round does not resume and receives no automatic refund or payout. Your next visit starts ready.
