How the Board is Generated
A four-by-four Mines board is drawn uniformly from all boards that satisfy a specific constraint: across all rows, there are exactly two nonempty occupied runs in total. The mine count you choose defines this exact finite board support. Draws are uniform over that support, not over all unconstrained boards.
Payout Formula and Limits
After any safe path, the gross cashout is calculated as 96 percent of the captured stake times the initial support size divided by the current compatible support size. Cells with zero conditional safe probability are disabled. Cells whose safe quote would exceed 1000 times the stake are also disabled. When no eligible cell remains, the current quote is automatically banked.
Controls and Modes
- Board: Four-by-four grid.
- Mine Count: Choices are limited to the exact nonempty support configurations in the source.
- Banking: Manual bank becomes available only after at least one safe reveal.
- Auto Queue: No auto queue; manual idle-only refill.
Wallet and Persistence
The wallet starts with an initial balance of 1000. A manual refill while idle below 10 sets the integer wallet to 1000 and preserves fractional carry. Fractional carry persists across settlement, refill, and reload. Settled balance persists locally, including zero. An unfinished round ending on reload ends without refund or resume.
