First, put dots around the number 0, no light bulbs here.


03

Put four light bulbs around the number "4."


04

Put light bulbs where the number in the cell and the number of white cells around it match.


05

Put a light bulb in cell A so it becomes illuminated.


06

Light bulbs are not allowed in cells B and C, so put a bulb in the cell above B and one in the cell below C.


07

As you put light bulbs, more cells become illuminated. Cells not illuminated by another light bulb get their own light bulb.
