Happy 3D Puzzle Collection

The Happy 3D puzzles are a collection of several puzzle cube versions or sets. An entire foam collection: from 2D to 3D, from easy to mindboggling. All with a different degree of difficulty. Each set has six coloured foam puzzles that are flat-packed in their frame.
The core puzzles, the Happy family, are (when made) cubes of 4 cm. Besides that we have the Happy Cube XL and Smart Cube versions of 5 cm cubes and the very cute micro's of 2 cm.

Brain teasers in 4 graded sets for all ages! Little Genius is made for kids. Happy Cube is the original version. Profi Cube and Marble Cube are the harder ones.
But that's not all. Each version consists of a range of six puzzles, each with a different difficulty and colour. The colour of the cube indicates the difficulty. With each colour the challenge gets harder. From easy till difficult the range varies usually from blue to green, yellow, orange, red and purple.

Planet Cube
Extraterrestrial challenge


The Planet Cube is a 3D cube of 3,5 cm with 6 edge puzzle pieces. This cube is smaller than the original Happy Cube. Planet Cubes puzzle pieces can not be interconnected with the Happy Cube 5 edges puzzles of the oiginal 4 cm 3D cube.
The Planet Cube is more difficult than Happy Cube for the human mind because it doesn’t resembles the human hand. A puzzle piece of a Happy Cube resembles the five fingers of the hand. Because of that the mind can easily reflect the image. Are you ready for this extraterrestrial challenge?

Each of the six Planet Cubes has a different shape, colour and solution. Every model has it’s own name which refers to a planet in our solar system: Venus, Mercury, Jupiter, Neptune, Mars and last but not least: the purple puzzle refers to our precious planet Earth.

The cubes can be combined together to make large constructions. The set exists of 6 puzzles, hence it has less possibilities than the Happy Cube family which alows interconnections between the family members.
