Two players attempt to control the majority of spaces on a customizable board by spreading, jumping and infecting. Spreading involves adding a new piece adjacent to an existing one. Jumping means moving a piece two spaces away. Whenever a piece is placed adjacent to opposing pieces these are infected, meaning replaced with friendly ones. Hexxagon is an adaptation of the game Ataxx for a hexagonal grid instead of a square grid board. Like Ataxx, it has only been published as computer software.
