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.

Who it is for

For solo solvers who enjoy learning how a small action changes a larger pattern. It suits experimenting carefully, recording the effect of a press and using that knowledge on the next attempt.

Features

  • A grid of lights with on and off states.
  • A press changes the selected light and neighbouring lights.
  • Solve the board by switching every light 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.
