An abstract strategy game of building networks. The board consists of a hexagonal grid of hexes. Six hexes, located along the outer edge of the board, are labelled with a letter. Players, on their turn, add a path of their colour that connects two adjacent hexes and a wall that blocks a path from being built there. In addition, players may convert a path to a wall and a wall into a path. Eventually, the six lettered hexes will be connected by a network of paths. At this point, the game ends. There will be three scoring routes on the board. Each scoring route connects a pair of letters and usually contains paths owned by more than one player. Players score one point for each path they own along each route. The player with the highest score wins. To assemble the print-and-play version, simply print the board, insert it into a plastic sheet protector, and use dry erase markers to draw paths and walls. Alternatively, print one of the other boards, which have smaller dimensions but larger hexes, and use Settlers of Catan roads as paths and small counters as walls.
