Once in a while a board game arrives that combines complete simplicity with brilliant game design - welcome to Callisto. Callisto will have everyone in your family enthralled, from young to old. It's very easy to learn (just one small page of rules), but uses strategic skills, dexterity and a bit of luck to master. The game was designed by the world's most accomplished game inventor, Reiner Knizia. He has won major international board game awards, including the most influential, the Spiel des Jahr in Germany, 2008.
