If you like using brain power and strategy to beat games, then you are going to love Lights Out. It truly is a test of intelligence, problem solving, and planning. The objective is to turn all of the lights on the board off. By clicking a light, it will reverse the state of every adjacent light. So, if the 4 surrounding lights were on and you clicked the middle light, the surrounding lights would turn off. Keep doing this until you figure out a way to get them to all turn off.
