DeLights brings an extension to a classic game (Lights Out) to the Mac!
The goal is to turn off all the lights by tapping the squares. Tapping a square will toggle the light of the square as well as those immediate to the right, to the left, just above, and just below as well. Dont be fooled by the simplicity of its look. It is harder than you think! But if you know linear algebra, you could solve it mathematically!
