  • Patent number: 4003579
    Abstract: A scoreboard is provided for use primarily in scoring dart games. Typically, darts may be played in a number of different ways with each game having its own rules and scoring procedures and each requiring a different score board or sheet for each game. The present invention discloses a permanent, multi-purpose scoreboard having a hard transparent front wall providing a writing surface formed with a U-shaped center core defining a recess open along one edge to receive a set of score sheets, each representing a different game and printed with scoring indicia unique to each game. The board may be wallmounted with a grease pencil attached for keeping score on the transparent front wall. The various score sheets may be rearranged as desired depending upon the particular game to be played.
