Board Support and Mechanics
The game uses a 4x4 grid (16 cells). The board is drawn uniformly from all configurations where the mine count matches the selected setting and satisfies the anti-diagonal occupancy alternation rule. This creates an exact finite support set rather than a random draw from all possible boards.
Each safe reveal filters this support. The gross payout quote is determined by the formula: Gross Quote = 0.96 × Captured Stake × Initial Support Size / Current Compatible Support Size. Cells with zero conditional safe probability or those exceeding the 1000x stake cap are disabled. When no eligible cells remain, the current quote is automatically banked.
Payouts and Constraints
| Feature | Detail |
|---|---|
| Gross Multiplier | Calculated as 0.96 × (Initial Support / Remaining Support). |
| Cap Limit | Any safe reveal that would exceed 1000 times the stake is disabled. The quote is automatically banked if no eligible reveals remain. |
| Stake Lock | Captured stake and mine count remain locked throughout the active round. |
| Refill | No automatic refill occurs during an active round. Manual refill is only available when idle and balance is below 10, setting the wallet to exactly 1000. |
Exact Math Evidence and RTP
The exact gross RTP is 0.96 across all modes. Simulation measurements provide supporting observations but are not the mathematical law. Fractional carry persists across settlement, refill, and reload.
| Mines | Policy | Exact RTP | Measured RTP | Surviving Boards |
|---|---|---|---|---|
| 3 | 0 | 0.96 | 96.065% | 22 |
| 3 | 5 | 0.96 | 95.849% | 1 |
| 4 | 0 | 0.96 | 96.048% | 110 |
| 4 | 5 | 0.96 | 96.535% | 1 |
| 5 | 0 | 0.96 | 95.906% | 330 |
| 5 | 5 | 0.96 | 96.626% | 1 |
Wallet and Persistence
The demo wallet uses browser localStorage for settled balance and fractional carry. There is no account login flow. If the balance is below 10 while idle, a manual refill sets the balance to exactly 1000. Unfinished rounds end without refund or resume upon reload. Fractional carry is preserved across these events.
Controls and Modes
Controls are locked during an active round. Stake, mine count, and refill are unavailable until the round ends. Manual bank becomes available only after at least one safe reveal. Sound remains available throughout. There is no auto queue; all actions are manual.

Frequently asked questions
How is the board support defined?
The board is drawn uniformly from all 4x4 configurations with the selected mine count that satisfy the anti-diagonal occupancy alternation rule. This creates a specific finite support set, not a random draw from all possible boards.
What happens if no eligible reveals remain?
The current quote is automatically banked. Cells whose safe quote would exceed 1000 times the stake are disabled before a reveal.
Does the wallet refill automatically?
No. A manual refill is only available when idle and the balance is below 10, setting the wallet to exactly 1000. No automatic replenishment occurs during or after rounds.
