Lights Out Pro

This is a simple logic game in which the objective is to turn all of the lights off. When you touch a light, that light and the 4 that are touching it will turn either on or off. There are 3 different game boards: Kids Mode, a 3x3 grid, Advanced, a 5x5 grid, and Master, a 7x7 grid. All puzzles have been proven solvable, so don't give up!
