In 2007, Haba released a game called Planet der Sinne (Sensory Planet) that includes a range of games to teach children about the different senses. This game is an expansion, sort of anyway. It is all about the sense of sight, and some of the games and exercises are used in the original Planet der Sinne but some are new. The box is jammed with components to play over a dozen games, all using visual clues and observation as the idea. Some are just exercises, while others are fun games that work for the family.
