The goal of the game is to turn off all the lights. By pressing a light on the board, you will change the state of the selected light and all adjacent lights. Try to get all the lights out in the lowest number of moves.

LightsOut can be played in Chess Knights (Vulcan- XL25) mode and supports Multi Touch making it possible to switch more than one light on/off at a time.

Can currently be played in three grid sizes, the 3×3 (small), the 4×4 (medium) and the 5×5 (normal/original).
