Minesweeper Drills

Small boards, one deduction each, no timer and no way to lose. Every drill is solvable by pure logic — and tells you which rule solved it.

Counting

A number equal to its covered neighbours means all mines. A satisfied number means all safe.

0 of 3 solved

The 1-1 pattern

Two 1s along a wall, and the cell one of them cannot be counting.

0 of 4 solved

The 1-2 pattern

A 1 beside a 2 along a wall: the far cell past the 2 is always a mine.

0 of 4 solved

The 1-2-1 pattern

Mine, safe, mine — the only arrangement that satisfies all three numbers.

0 of 4 solved

The 1-2-2-1 pattern

Safe, mine, mine, safe. The longer cousin of 1-2-1.

0 of 4 solved

Subset reduction

The general rule every pattern above is a special case of.

0 of 5 solved
