The Tangramino Book is part of the Brain Builder series of games designed to develop spatial logic through creative play. That means if you already have the building blocks from either the Architecto or Equilibrio games, all you have to do is buy the Tangramino Book for 60 additional two-dimensional challenges. From a cat and a mouse to a bird and a house, the illustrations in this spiral-bound book are color-coded so players can track their progress through six difficulty levels. Work your way through the book to enhance coordination, creativity and visual spatial skills.
