There are three different puzzles that range in difficulty starting with Beginner (Phase 1), Intermediate (Phase 2) and Advanced (Phase 3). Each puzzle has eight to 10 different numbered colors along with numbers on the puzzle board indicating where to place the numbered colored pieces. There are a wide variety of shapes in each puzzle that can have several colors on each piece. Fun and developmentally challenging, the puzzles teach color-matching, number-color-shape-word association and hand eye coordination.
