Lights Out is a puzzle game
Lights Out is a puzzle game. The game consists of a 4 by 4, 5 by 5 or 6 by 6 grid of lights - emojies. When the game starts, a random number of these lights is switched on. Pressing any of the lights will toggle it and the adjacent lights (on the left, right, above and below it - a '+' shape). The goal of the puzzle is to switch all the lights off, preferably in as few button presses as possible.
