Turn off every light
Lights Out
A grid of glowing lights, one simple rule. Clicking a light flips it and its up/down/left/right neighbors — chain the right sequence of clicks to turn every light off and clear the board.
How to Play Lights Out
Click or tap any light to toggle it and its orthogonal neighbors. Keyboard users can Tab to a light and press Enter or Space to toggle it.
- Work row by row from the top — clicking the light directly below any lit cell in the top row is often the fastest way to clear it for good.
- Every puzzle is generated to be solvable, so if the board looks hopeless, backtrack rather than assume it's stuck.
- A single click never affects just one light, so plan a move by picturing its full plus-shaped ripple, not just the cell you're tapping.
