Lights Out: Grid Puzzle

Lights Out is a classic puzzle game: every light on the board is lit, and each tap toggles that light along with its neighbors above, below, left, and right. Clear every light in as few moves as possible to win. The rules are simple, but tracing the chain reaction of each move is anything but — a perfect quick brain workout for your commute, a queue, or before bed.
． Multiple board sizes
Start with the beginner-friendly 4×4, then unlock 3×3, 5×5, and 6×6 as you clear levels. Bigger boards, deeper thinking.

． 28 classic levels
Carefully designed levels that ramp up in difficulty, so you can watch your solving skills grow one level at a time.

． Freeplay mode
Replay your favorite board size as many times as you like, whenever you feel like a quick puzzle — no progress pressure.

． Share a challenge
Send your solved board to a friend and see who can clear it in fewer moves.

． Achievements & stats
Streaks, best move counts, fastest times — all tracked automatically so you can watch your own records get broken.

． Pick up where you left off
Sign in with Google or Apple to carry your progress across phones and devices.

Free to play, with optional rewarded ads (for example, watch an ad for a hint) that never affect the core gameplay.

Turn off your brain — or rather, turn it on. Lights Out is waiting for you.
