💡 LightsOut

A grid of lights is on, and clicking one toggles it along with its orthogonal neighbors. Free, no ads, no login — play instantly on Bytecade Games.

How to Play

  1. Click a cell to toggle it and its adjacent neighbors (up, down, left, right).
  2. Corner cells affect 3 lights; edge cells affect 4; center cells affect 5.
  3. Turn off all lights to win.
  4. Every Lights Out puzzle has a solution — keep trying different cells.
  5. Work systematically — sometimes toggling the same cell twice cancels out.
