] Y is an abstract strategy board game, first described by Claude Shannon in the early 1950s. The game was independently invented in 1953 by Craige Schensted (now Ea Ea) and Charles Titus. It is a member of the connection game family inhabited by Hex, Havannah, TwixT, and others; it is also an early member in a long line of games Ea Ea has developed, each game more complex but also more generalized.
