Each of our "3D Multi-Layer Puzzles" tends to have more pieces. Please note the predominance of "negative space" in these puzzles (many pieces don't have their own hole, but have subtle clues as to where they go). They are for children who have mastered our single-layer puzzles and who are ready for an added level of difficulty. They range from 2 to 6 layers deep and are "3D" in nature. Puzzles in this group are for children ages 3 and up. (Specific age recomendations in each puzzle description.)
*Please note; Puzzles in this category have pieces that are too small for children under the age of 3 and so may be a choking hazard.
