Lights Out Lab
Every switch flips its neighbors — turn the whole lab dark!
How to play
Tapping a light toggles it AND its four neighbors — your goal is to switch every light off. It sounds simple until the patterns tangle. Each stage grows the grid and starts from trickier light patterns, with a move limit for extra pressure. Your progress is saved automatically, so you can come back and continue from the highest stage you have unlocked.
