  • Patent number: 4216968
    Abstract: A dart game having self-scoring and display means wherein the scoring is achieved by electronic computation after series actuation of various alphabetical, numerical or mathematical function inputs by an impact-type dart. A target panel comprises an array of individual alpha-numeric and mathematical function strike areas which will effect closing one of a plurality of associated pairs of contact points when impacted by the dart to thereby provide one entry of a plural-entry logic circuit. Upon completion of a predetermined number of entries by a player, the logic circuitry performs a mathematical function in accordance with the entry sequence and displays the result on a display board.
