About Lights Out
Lights Out is a logic puzzle where pressing one light changes that light and nearby lights. The goal is to turn every light off, but each press affects more than one square, so solving the puzzle takes planning.
How to play Lights Out
Click or tap a light to toggle it. The selected light and its neighbouring lights change state. Keep pressing lights until the whole grid is switched off.
Tips for playing Lights Out
Try solving row by row instead of pressing randomly. Watch how each press affects nearby lights, and use patterns from previous attempts. If the board gets messy, restart and apply what you learned.
Lights Out history and background
