What is the Lights Out?
Each tap toggles the light you press plus the ones directly above, below, left and right. The goal is to turn all the lights off. Every puzzle is generated from a solved board, so it can always be solved. Use Hint if you get stuck – it shows one light that is part of a solution.
How to use the Lights Out
- Choose a board size.
- Tap lights to toggle them and their neighbours.
- Turn every light off in as few moves as possible.
Strategy – “chase the lights”
Clear row by row: tap the light below each lit light in the row above. When only the bottom row is lit, the pattern tells you which top-row lights to tap and repeat.
This Lights Out is 100% free, needs no signup and runs privately in your browser – on phone, tablet or computer.
