I was at a recent match when this took place. During a 501 match a player hit a single20, trip20,then another trip 20. As he was walking to remove his darts one of the trip20 darts fell out. Leaving him with 80 points. I understand that he didn't get the points for the dart that fell out my question is this. In this same game the same player needed a double 16 to out. He hit a trip16 with his first dart samething happened it fell out but this time he busted? So my question is why didn't he get to shoot his other darts. If he didn't get points earlier when his dart fell out how can he bust when the dart fell out? I'm new to darts and still learning but this didn't seem fair at all.
