Lights Off

Turn off every light on the board.

Each press toggles a light and its neighbors. Can you leave the board in the dark?

How to play

• Pressing a cell toggles it and its four neighbors (up, down, left and right).
• The goal is to turn off all the lights.
• Stuck? Buy a hint with Pupicoins (5 to 20 depending on difficulty, H key): a cell that’s part of the solution will light up.

Lights Off: online race

Everyone gets the same board of lights at the same time. The first to leave it dark wins.
