Play Lights Out Online Free - Classic Turn Off Lights Puzzle Game
What Is Lights Out?
Lights Out is a classic electronic puzzle reborn for the web: the board starts with several lights randomly switched on, and tapping any light toggles it and its four neighbours — a plus-shaped group of up to five cells — flipping each from on to off or off to on. The goal is deceptively simple: switch off every light on the board, using the fewest taps. It plays free in your browser, no download needed.
How to Play Lights Out
- Read the board. Some lights are on, some off; you need them all off.
- Tap a light to toggle a plus shape. Tapping any cell flips itself and its four neighbours (up, down, left, right) — the corners and edges affect fewer cells.
- Chase the lights toward a solved board. Work top-to-bottom, left-to-right, using each tap to switch off the light above or to the left of the cell you press.
- Match the Par. Each level has a known optimal solution; the Par above the board is the minimum number of taps, and matching it proves you found the intended path.

Strategy Tips
- Chase top-to-bottom. The standard method is to resolve the top row, then work down — each tap turns off the light above it, so order matters more than cleverness.
- Never tap the same cell twice. Two taps on one cell cancel out, so the optimal solution never repeats a cell; if you are re-tapping, you are off the shortest path.
- Use the hint to find the optimal cell. When stuck, the hint highlights a cell from the true solution — study it to learn the pattern rather than just clicking through.
Lights Out FAQ
Is Lights Out free?
Yes — it is completely free on this site. No paywall, no download and no account; open the page and start tapping.
What does Par mean?
Par is the minimum number of taps needed to solve a level. Matching it shows you found the optimal solution; you can still win with more taps, but masters aim for par.
Why shouldn't I tap the same light twice?
Because a double tap toggles the same plus shape twice and cancels itself out — it changes nothing while wasting a move. The optimal solution never repeats a cell.
