Light Switch · Lights Off Logic Puzzle
Light Switch is a lights-off logic puzzle: every tap flips a light and its four neighbours, and the goal is a completely dark grid. Every level is guaranteed solvable within its move par, and the grids grow from 3×3 to 6×6.
How to play Light Switch
- Tap a light to flip it and the four lights next to it.
- Switch every light off before the timer bar empties.
- Finish within the move par for a bonus — a time-out costs a life.
Controls
Tap / click a light — or arrows / WASD + Space, R to reset.
Tips & tricks
- Clear the grid row by row: tap below each lit cell to push the lights down.
- Tapping the same light twice cancels out, so never do it on purpose.
