A smaller-box, shorter variant of Callisto - The Game.
 
 
Callisto's brilliant design, including a board that changes surface according to the number of players present, is among one of the features that make this game so unique. While the goal is simple - to be the first player to place all of his/her tiles onto the board-the shapes of the tiles and additional columns make winning quite tricky. The game plays out like a competitive puzzle, and finesse and cunning are required to triumph.
