Fill in the squares and find the picture
The numbers beside each row and column say how many squares in a row to fill in. When the grid is complete, a picture appears.
Also known as griddlers or picross. Four sizes, from 10×10 up to a 30×30 galleon.
The numbers on each row and column say how many squares in a row are filled, in that order, with at least one empty square between groups.
Paperback, 8.5 × 11 inches, white paper and big grids. The answers are at the back, at no extra cost. Every puzzle goes through a program that looks for a second solution before it is printed: if it finds one, the puzzle is thrown away.
