Lights Out

How to Play

Goal: Turn off every light on the board.

Controls: Click or tap a tile. That tile and its four orthogonal neighbors (up, down, left, right) flip between lit and off.

Rules: Every puzzle is generated from an all-off board, so a solution is always guaranteed. Use New Game for a fresh board, Reset Puzzle to restart the current one, and Hint to reveal a tile that belongs to a solution.
