💡Lights Out
Classic Lights Out puzzle: tapping a light flips its cross-shaped neighborhood, turn all lights off to win across 3 board sizes
Lights Out
Tapping a cell flips itself and its orthogonal neighbors — turn every light off to win.
Tap a cell to flip the cross-shaped area; solve the puzzle by switching all lights off. Every generated puzzle is guaranteed solvable.
How to Use
Lights Out is a classic logic puzzle: some lights on the grid are on, and tapping any cell toggles it together with its up/down/left/right neighbors. Turn everything off to win. Every puzzle is generated by reverse-toggling from a dark board, so a solution always exists. The classic technique is 'light chasing': from the second row onward, each tap is dictated by the lit cells in the row above.
FAQ
Is every puzzle solvable?
Yes. Each puzzle is created by applying legal toggles to a dark board, so at least one solution exists.
Any general tips?
Use light chasing: let each row's taps clear the row above, compressing the puzzle to the last row.
