Light Up (a.k.a. Akari): The goal is to place "light bulbs" in certain white squares to illuminate all white squares. A cell is illuminated by a light bulb if they're in the same row or column, and if there are no black cells between them. Also, no light bulb may illuminate another light bulb. Some of the black cells have numbers in them. A number in a black cell indicates how many light bulbs share an edge with that cell. Hints: Use a circle to represent a light bulb, and a small dot in the center to indicate a square illuminated by a light bulb Puzzle courtesy of www.puzzle-light-up.com.
