About this app
Lights Out is a daily logic puzzle in which tapping a cell flips that cell and its orthogonal neighbors in a cross pattern. Turn off every light using as few taps as possible, then compare your result with the displayed minimum. A Practice tab provides unlimited new boards, while hints, reset controls, streak tracking, and result copying support repeat play.
