The game uses a four-by-four board drawn uniformly from all boards with the selected mine count that satisfy a specific public support rule: No row contains contiguous pattern 101. Safe reveals condition this legal-board support; after any safe path, the gross cashout is 96 percent of captured stake times initial-support-size divided by current compatible-support-size.
Board Support and Rules
The board is a 4x4 grid. The mine count choices are only the exact nonempty support configurations in the source. Draws are uniform over that support, not over all unconstrained boards. Each safe reveal filters the support.
Known-certain mines are disabled. Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed 1000 times stake are disabled. When no eligible cell remains, the current quote is automatically banked.
Payout and Settlement
The score function is defined as: Gross quote = 0.96 × captured stake × initial support count / current compatible support count. Mine returns zero.
| Parameter | Value/Rule |
|---|---|
| Gross Payout | 96% of captured stake adjusted by support ratio |
| Cap | 1000× stake (disables transitions exceeding this) |
| Auto-Bank | When no eligible reveal remains |
The exact expected gross RTP is 0.96 across all modes. Simulation measurements are supporting sample observations, not the mathematical payout law.
Controls and Modes
- Board: Four-by-four
- Lock: Captured stake and mine count are locked throughout the round
- Bank: Manual bank becomes available only after at least one safe reveal
- Queue: No auto queue; manual idle-only refill
A manual refill while idle below 10 sets the integer wallet to 1000 and preserves fractional carry. Sound remains available during play.
Wallet and Persistence
The wallet distinguishes between a manual idle-only restoration and adding coins. Restoration sets the balance to exactly 1000. Fractional carry persists across settlement, refill and reload.
Settled balance persists locally including zero. An unfinished round ends without refund or resume upon reload. Busy controls (Stake, mine count, refill) are locked while the round is active.

Frequently asked questions
How is the board drawn?
The board is drawn uniformly from all legal boards with the selected mine count satisfying the rule: No row contains contiguous pattern 101.
What is the wallet restoration rule?
A manual refill while idle below 10 sets the integer wallet to exactly 1000. Fractional carry is preserved. This is not an automatic replenishment.
Is the 18+ age gate implemented?
18+ is this guide's own intended audience policy, not a claim about local law or an implemented age gate.
