Havannah is a two-player abstract strategy board game invented by Christian Freeling. It belongs to the family of games commonly called connection games; its relatives include Hex and TwixT. Havannah has "a sophisticated and varied strategy" and is best played on a base-10 hexagonal board, 10 hex cells to a side.[1]
The game was published for a period in Germany by Ravensburger, with a smaller, base-8 board suitable for beginners. It is nowadays only produced by Hexboards.[2]
