How to play Switch Off
- Some squares of the grid are lit.
- Tap a square: it flips, along with its four neighbors above, below, left and right.
- Turn every light off to win.
- The goal shows the smallest number of moves that solves this grid. Undo takes back your last move, and Hint makes a square of the shortest solution glow.
Tips
- Tapping the same square twice cancels itself out: each square needs at most one tap.
- The order of your taps does not matter, only which squares you tap.
- Chase the lights: go row by row and tap the square under every light still on.
- When only the bottom row is left lit, try a different set of taps on the top row and chase again.
About Switch Off
Switch Off is a classic lights puzzle: one tap changes five squares at once, so every move undoes part of the last one. It looks like luck at first, then turns into pure logic.
Every grid is built by tapping squares on a dark board, so it can always be solved, and it never solves in a single tap. Four levels go from a small 3 x 3 board to a 5 x 5 board that starts almost fully lit.
Points and badges
Finishing a game of Switch Off earns points for your level. Four badges are waiting in this game, from bronze to diamond: each one says what to do and adds bonus points.
Questions

It is the smallest number of taps that turns this grid off. Match it for a perfect game and bonus points.
Is there a method that always works?
Yes: chase the lights row by row, then adjust the top row and chase again.
