Tap tiles on a grid where each press flips the lit state of that tile and its four neighbors, working to switch the entire board off. The challenge is finding the exact sequence of taps that cancels every light without leaving a stray one glowing.
How to play Lights Off
- Look at the grid of lit and unlit tiles.
- Tap a tile to toggle it and its up, down, left, and right neighbors.
- Plan a chain of taps that turns lit tiles off without relighting others.
- Clear the whole board to solve the level and move on.
Tips & strategy
- Work top-to-bottom: use each row to clear the row above it.
- Order of taps doesn't matter, only which tiles you tap an odd number of times.
- If you're stuck, retry from a fresh board rather than chasing one stubborn light.
Controls: Tap or click a tile to toggle it and its neighbors.
