Lexogon challenges players to think of a word that uses the three clue letters in order, but arranged in a special way required by the color category indicated on each card. In this game of risk, luck and strategy, two to six players must depend on the roll of the die, the Clue Cards and their way with words. Lexogon One, at a middle-school vocabulary level, features two-letter clues and is great for classroom and family play. “It challenges you to think about words in a way that is entirely new,” President John Tyler of Tippecanoe told TDmonthly. Launch date: October 2006.
