Game introduction
What is Lights Out?
Lights Out is a toggle puzzle where each press changes one light plus its horizontal and vertical neighbors. The goal is to make every square dark.
Every new board is created by applying valid presses to a solved grid, so a solution always exists. Difficulty increases the grid size and scramble length.
