LightOut (v. 1.0) Разработано Lazyer Studio

Lights Out is an electronic game, released by Tiger Toys in 1995.
The game consists of a 5 by 5 grid of lights, when the game starts, a set of these lights are switched on (White tile).
Pressing one of the lights will toggle it and the four lights adjacent to it on and off (Diagonal neighbours are not affected).
The game provides a puzzle, to switch all the lights off (Black tile), preferably in as few button presses as possible.
