A novel missed-hit detection and player proximity detection system for an electronic, automatically scored projectile target game apparatus wherein the scoring system thereof is automatically deactivated whenever a player comes within a proscribed distance range from the game and wherein the impact of a projectile which misses the target, yet strikes the front of the game registers as a non-scoring 'missed-hit' and is deducted from the number of remaining throws in that round.

Missed hit and player proximity detection system for electronic

A novel dart game which allows one or more players to participate and which has a dart board mounted over a matrix switch and with segments to actuate the matrix switch when struck by a dart thrown by a player and which uses a first microcomputer to scan the matrix switch to detect where the dart struck the dart board and a second microcomputer which performs numerous functions such as totalizing the score for each player, actuating indicators which inform the players of the conditions and score of the game for each player. The novel dart board is formed with movable segments which are guided by guide ribs so as to provide smooth and accurate response of the segments to darts received on the board.
