this has been brought up many times but this is the official ruling

If the Eight-Ball is potted on any break, the balls are re-racked and the same player will break again. When the Eight-Ball is potted on the break, all other aspects of the shot are ignored. (Except if a Serious Foul or breech of the "Spirit of the Game" occurs).

i'm not saying that this should be followed, programming the game that way would presumably be hard. but maybe if it just restarted the game, and no one wins
