— The basics

What is Lights Out?

Lights Out is a beautifully simple grid puzzle that has fooled players for decades. A grid of tiles is lit up. Tapping any tile flips that tile and its four neighbours between on and off. The goal: turn every tile off in as few moves as possible. It sounds trivial. It is not — every tap changes five squares at once, and what looks like a clear move now can lock the whole board later.

The depth of Lights Out comes from how every press has consequences in multiple directions. There is real, provable mathematics behind which boards are solvable and which patterns of moves clear them. You do not need to know any of that to enjoy the game, but you might notice that your brain starts forming little rules of thumb after a few solves — "always press the edges first", "never press the centre twice" — which is exactly the kind of pattern recognition the puzzle is designed to grow.

Beginner tips for Lights Out

Work top to bottom. Clear the top row first, then use the second row to clean up what the first row left behind.
Pressing the same tile twice cancels out. Do not waste moves repeating yourself.
Edges are easier than centres. Edges affect three tiles; centres affect five and create more chaos.
Plan your last three taps. The endgame is where most "almost solved" attempts die.
Replay solved boards. Trying to beat your move count on a known board teaches the patterns fastest.
