Switches free online: each tap flips a light and its four neighbours. Turn them all off in the fewest taps. Always solvable, hints and a daily challenge. No ads.
A grid of lights, some on and some off. Tapping a square flips its light and the lights of its four neighbours: the ones that are on go off and the ones that are off come on. Turn every light off.
A clear challenge. From the start you can see how many taps it can be solved in. Switching everything off wins; doing it in the exact minimum is the challenge.
Always solvable. Every board can be switched off, and the game always knows the shortest way. The hint points to a square on that way from wherever you are, and undo is free.
Three modes. Classic with four levels, from 4 × 4 up to a 7 × 7 Expert. A Daily challenge with the same board for everyone. And Zen, with no timer.
Genuinely calm. No ads, no purchases and no accounts. Your games, stats and achievements stay on your device.
Tap a square to flip its light and its four neighbours. The order of the taps doesn't matter, and tapping the same square twice leaves it as it was.
