Havannah, a connection game using hexagonal cells like Hex, offers "a subtler strategy and much more varied tactics" . The game was published by Ravensburger in 1981 and marketed for ten years, winning critical acclaim. In 2002, Freeling offered a €1,000 prize for any computer program in ten years that could beat him in even one game in a 10-game match, believing the nature of Havannah made the game difficult to program and therefore best played by human strategic thinking. In October 2012, via Internet, a 10-game match was conducted between Freeling and three Havannah bots. Freeling won by +7−3=0, losing two games to Lajkonik (Poland) and one game to Castro (Canada).
