Lights Out is a logic puzzle played on a grid of glowing tiles. Each move flips the tile you choose and its horizontal and vertical neighbours. A light can turn on as easily as it turns off.

Start with a 3 × 3 board to learn the pattern, then explore 4 × 4 or 5 × 5. Every board here can be solved. Take your time, undo a move, or ask for a hint.
