Each foam puzzle has only one solution and has its own shapes, colour, and name. The puzzle names refer to famous world citizens. Take for example the orange puzzle, named after the famous painter Rubens. 

You can recognize the Happy Cube Pro by its bright colours and camouflage markings! Each set comes with six coloured puzzles, flat-packed. They need to be turned into six cubes, each one a little harder than the previous. Once they have been made, the next stage is to fit them all back into their flat packs, which is easier said than done! Multiple shapes can then be made out of pieces from each cube. Enormous fun for hours... and don't think they're just for children - adults get addicted fast!
