Griddlers are amusing tests of skill and logic. The aim is to discover the picture hidden by the grid by filling in some squares as solids and the remainder with dots using your powers of deduction. There are numbers attached to each grid and they tell you how many squares are to be filled in - all you have to do is deduce which ones! When completed the solids form a picture.
