Lights Out
Moves 0
Best 0
Turn every light off. Clicking a cell flips it and its 4 neighbours.
How to play
- The board is a 5x5 grid of lights, some on and some off.
- Tapping a light toggles it and its four neighbors (up, down, left, right).
- Your goal is to turn every light off.
- Every board is always solvable — do it in as few moves as you can.
Strategy & tips
- Work top to bottom: clear the top row, then use the row below to fix what remains.
- The "chase the lights" method — press the cell below any lit light, row by row — solves most boards.
- Remember pressing a cell twice cancels out, so avoid undoing your own moves.
- Plan a few presses ahead; a single tap changes up to five lights at once.
- Fewer moves means a better score, so look for presses that clear the most lights.
FAQ
Is every board solvable?
Yes. Each board is scrambled from a solved state with real presses, so it can always be turned off.
Is Lights Out free?
Yes — it plays free in your browser with no download or sign-up, on desktop and mobile.
How does tapping work?
Tapping a light flips it and its four orthogonal neighbors. Corner and edge cells flip fewer lights.
Does it track my best?
Yes. Your fewest-moves best is saved in your browser between games on the same device.
