  • Patent number: 4314703
    Abstract: Dartboard has a first game side which is divided into fifty-two dart target spaces with each space carrying indicia corresponding to the fifty-two cards of the standard bridge deck. Each target space has a slot adjacent one end thereof into which a slot card each having one of the indicia of the standard bridge deck is inserted to thus hide the indicia from other players. The dart board is rotatably mounted to increase random chance and with the players taking turns throwing darts, dart games employing rules similar to poker and other card games can be played with the board. The reverse of the board is divided into spaces, each of which carries the indicia of one side of a six-sided die. Thus, by throwing darts to the reverse side of the board, games having rules similar to dice games can be played, but also employing dart-throwing skill.
