Frequently Asked Questions

How do I play Mine Sweep?

On first click, the game generates a solvable board by repeatedly creating random mine layouts and running a constraint-based solver until one passes -- guaranteeing every puzzle is completable through logic alone with no guessing. The solver uses two passes: single-cell neighbor deductions, then constraint-pair subset analysis. Revealed zeros trigger recursive flood-fill to auto-reveal adjacent empty cells.

How do I play mine sweep?

Left-click to reveal a cell. The number shown tells you how many adjacent cells contain mines. Use logic to determine which cells are safe and right-click to flag cells you believe contain mines.

What grid sizes are available?

Beginner (9x9 with 10 mines), Intermediate (16x16 with 40 mines), and Expert (30x16 with 99 mines). Each size offers a different level of challenge and time commitment.

Is the first click always safe?

Yes. The mine placement ensures your first click always reveals a safe cell, so you never lose on the first move. This is the standard behavior in modern mine sweep implementations.
