In this gravity-defying, 3-D word-building game, two to four players are challenged to add stacking letters to a tower to form words up, down or sideways to earn points. They must be careful, though, as any new letter could send the Konexi into a full collapse. The game comes with 26 red letters, a die, a mover, a pad and pencil, and a rules manual. Launch date: Fall 2010 (specialty and mass retailers).
