Light Up

A single bulb can light a whole corridor, but bulbs must stay out of each other's sight. The numbered walls tell you where to start.

How to play

Click a white cell to switch on a bulb. Its light travels straight until a wall. Light every open cell and match each wall number with that many bulbs directly beside it.

Playing tip. Look at the numbered walls before adding bulbs. Two bulbs in the same clear line can see each other, so one of them must move.
