- 3Keep clicking to turn off every light on the board.
- 4Every puzzle is guaranteed solvable.
- 5Try to solve it in as few moves as possible.
FAQ
Is every puzzle solvable?
Yes — every puzzle is generated by scrambling from a fully-off grid using the same toggle moves you solve it with, so a solution always exists.
Is my best score saved?
Yes, your fewest-moves record is tracked separately for each difficulty.
