Taliesin Master Game is a board game invented by Ronald William Astle and distributed in 1981 by Talforce Ltd. The game was notable for being released in three versions: • The Starter Game, which consisted of moving chess-like pieces on a circular board. • The Master Game, which built on the Starter Game by adding an intricately designed three level playing area. • The Executive version, which featured circular glass boards. The game was sold in Harrods, Hamleys, John Menzies and also through advertisements in Mensa magazine.
