Pentomino Puzzle Set - with 65 challenge cards
The Pentomino Set is a classic mathematical puzzle that offers 2D and 3D challenges with thousands of solutions. Each set contains 13 pieces. 12 of these pieces are different shapes that are all formed from 5 cubes in different combinations. Because “pento” is a Greek prefix for “five”, that number is a central theme for Pentomino. The playing pieces represent all possible combinations of 5 cubes that are joined together edge to edge. To complete the set, there is 1 square piece made from 4 cubes.
