Lights Out

How to play · Lights Out

The board starts with some lights glowing. Switch every light off to win. Each puzzle is guaranteed solvable.

Tapping a light toggles it AND the four lights directly above, below, left and right of it. On becomes off, off becomes on.
Lights on an edge or in a corner have fewer neighbours, so they flip fewer cells.
The whole puzzle is about the order of taps. Find a sequence that leaves the entire grid dark, using as few taps as you can.
