This includes 6 different foam cube puzzles. With each cube puzzle the difficulty gets harder!

There are three main missions for this six-piece foam cube.

The first is to build a perfect cube (3D), the second is to put the pieces back into the frame (2D), and lastly you can combine several Happy Cube puzzles together to create a multi-dimensional shape. In the Happy Cube range, there are six different puzzles (blue, green, yellow, orange, red and purple). 

This is a single player game.
