About
Lights Out is a classic logic puzzle played on a 5x5 grid of lights. Each press flips a plus-shaped group of cells, so moves interact with each other and order does not matter. Puzzles here are built by scrambling a solved board, which guarantees that a solution always exists.
Tips
- Pressing the same cell twice cancels out, so a solution never needs a cell more than once.
- Work top row by top row: clear each row by pressing the cells directly below the lights that are still on.
