Ultimate IQ Test, all in 38 puzzle. Can you make every row add up to 38? There are 15 rows in all directions to complete (the pieces are hexagons, not squares), each row made up of 3, 4 or 5 pieces. This brilliant concept allows you to complete the puzzle by using every number from 1 to 19!

Contemporary and clear - crisp and clean. The IQ Test range covers many of the best classic puzzles as well as a good selection of our favourite brand new designs. All boxes are made from stiff folding box board with white panels on the front and top, and either blue, green or red on the other sides.
