What?

What do they call this type of puzzle? I want to see if I can find some on-line.
It has a grid of squares.It has numbers above and to the left of the grid.
You have to deduct which squares to shade in from these numbers.
Sometimes the shaded squares form a pattern or picture.

Hi Geo,

They're called nonograms. I see that there are some that you can solve online.

Check your email.

Big Fish Games has a lot of them - let me know if you would like titles. They are numerous.
