Complete guide to playing Lights Out — rules, controls, tips, and strategies.
Lights Out is an electronic puzzle game originally released by Tiger Electronics in 1995. The game consists of a 5×5 grid of lights that can be toggled on or off. Pressing a light toggles it and its adjacent neighbors. The puzzle is rooted in linear algebra over GF(2) and has been extensively studied in mathematics.
Click on any light in the 5×5 grid. This will toggle that light and its immediate neighbors (up, down, left, right) — lights that are on will turn off, and lights that are off will turn on. Your goal is to turn ALL lights off. Think carefully about each move, as every click affects multiple lights. Solve increasingly difficult patterns as you progress through levels.
