How to Play Lights Out
Tap any square to switch it on or off. The squares directly above, below, left, and right also switch. Your goal is to make the entire 5ร5 grid dark. Every generated puzzle is created from a solved board, so it can be completed.
Lights Out Strategy
Work row by row. After deciding the first-row presses, press the tile directly below every lit tile to clear the row above it. Avoid random tapping: repeating the same tile twice cancels that move. Try to beat your saved best move count.
