5X5: A Lights Out Clone For Windows Mobile

5X5 is a small Lights Out clone for Windows Mobile. The game consists of a 5 by 5, 7 by 7, or 9 by 9 grid of lights; when the game starts, a set of these lights are switched on. Pressing one of the lights will toggle it and the four lights adjacent to it on and off while the diagonal neighbors are not affected. The aim of the game is to switch all the lights off. The game is free and will run on all touch screen Windows Mobile devices with virtually any display resolution. Spotted on 1800PocketPC.
