Lights Out
Turn off every light on the grid.
How to play
- Click a light to toggle it — and its up/down/left/right neighbours flip too.
- That ripple is the whole puzzle: every click changes five lights.
- Work out an order that leaves everything dark.
- All lights off wins.
Controls
Click a light to toggle it and its neighbours
How you earn
Turning every light off unlocks the bonus.
Tip
Clear it top-to-bottom: click the light directly under any lit one, row by row, and the board resolves.
