How to play Light Up
Place bulbs on the board to light every empty square. Bulbs cannot shine on one another, and numbered walls must have the indicated number of adjacent bulbs.
Controls
- Click an empty square to place or remove a bulb
- Choose a level; use Hint or Show solution if needed
Tips
- Light travels along rows and columns until it meets a wall.
- Use numbered walls to work out bulbs in nearby squares.
