Light Up — How to play and useful tips
Place bulbs to illuminate every white cell. Follow clues and beams through fresh stages.
Controls
- Bulbs cast light horizontally and vertically until a wall. Illuminate every white cell to finish.
- A numbered wall needs exactly that many adjacent bulbs, counting up, down, left and right. Bulbs must not shine on one another.
Playing tips
- Switch between bulbs, no-bulb marks and erasing. Hints explain a deduction when you need help.
