Lights Out
Tap cells to flip their neighbours and turn every light off. The classic Lights Out puzzle, 3 difficulties.
How to Play đĄ Lights Out
The 5x5 grid starts with a mix of lit (yellow) and dark cells. Tap any cell to toggle it along with its four orthogonal neighbours â up, down, left and right. Cells on an edge or corner toggle fewer neighbours. Your goal is to turn every single light off. There is no timer; the game just counts how many taps you use, and your best (fewest moves) is saved per difficulty. Easy, Normal and Hard differ in how scrambled the starting board is. Every puzzle is guaranteed solvable. Tip: work row by row from the top, and use Undo to experiment without restarting.
