Happy Cube Junior is the ideal first 3D puzzle for children approximately 3 to 7 years old. From six color-coordinated pieces, assemble a perfect cube and then store the pieces back into the flat frame. A simple idea that brings lots of joy and helps develop fine motor skills, hand–eye coordination, and patience.

The individual challenges increase in difficulty—from assembling the cube, to returning the pieces to the frame, to creating larger 3D structures by combining additional cubes of the same group. The Junior series uses clear difficulty icons (e.g., animals) and is designed to entertain children while subtly teaching them.
