At the beginning of the game when all cups are in play if the first cup made is the bitch cup (the very center cup in the middle " leaving a "hole in the middle of all the cups the shooter can try and make his next ball or any balls after land in the "black hole" or the space in the middle of all the cups if the ball lands and stays in the black hole than any and all cups touching/making the hole must be removed as if a black hole opened up and sucked all the closest cups into it. You should be left with the 3 corners of the original rack and nothing else after this shot is made. This also counts and a made cup if there is a balls back, or heating up opportunity.
They really thought I was gunna lose until I hit that black hole and caught back up.
