Toggle Pattern

A move flips the chosen light and its four orthogonal neighbors, with edge cells naturally affecting fewer squares.

Real Controls

Pointer taps, keyboard focus, mobile buttons, and gamepad input all call the same pure toggle function.

Saved Best

The lowest move count for each board size is stored locally, so quick 3x3 clears do not overwrite 7x7 records.

Lights Out FAQ

Toggle lights until every square is dark. Each move flips the selected light plus its orthogonal neighbors above, below, left, and right.
These boards are generated by applying legal toggles to a solved board. That means the puzzle has a known path back to all lights off.
Yes. Arrow keys, WASD, the d-pad, or the left stick move the selection. Enter, Space, A, or Cross toggles the selected light.
Work from the top row downward. Once you leave a row, use the row below it to turn off any lights left behind. The final row tells you whether your choices lined up.
