Switch 'Em is a puzzle game based on the old hand-held games Merlin, XL-25, and Lights Out.
Switch 'Em is a game that's easy to learn but difficult to master. It consists of a 5 by 5 grid of lighted buttons. The object of the game is to turn all the lights off in the fewest moves possible. The 'gotcha' part of the game is when you toggle a light on/off, the 4 adjacent lights are also toggled.
Switch 'Em is now available in the App Store.
