Lights Off
The classic logic puzzle: tapping a cell flips it and its 4 neighbours. Turn every light off in as few moves as possible. Hundreds of levels of rising difficulty, grids growing from 3×3 to 6×6, every level guaranteed solvable.
目标
Make the whole grid dark (all lights off). Each tap flips the cell you touch plus its 4 orthogonal neighbours.
