Y is an abstract strategyboard game, first described by John Milnor in the early 1950s.[1][2][3] The game was independently invented in 1953 by Craige Schensted 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 Schensted has developed, each game more complex but also more generalized.
