What is a double bust in darts?

Answer 1

A bust, which is called a burst in Europe, is throwing more than you need to complete an '01 game. It's also called a bust when you throw exactly the points that you need, but your last dart was not a double (I'm referring to real darts; you do not need to double-out in soft-tip darts). Leaving yourself one point is also a bust since there is no way to set up for a double-out from one point.

When you bust, your score remains what it was before you began your turn, and the next player is up. If you're counting darts for statistics, the turn in which you busted counts as three darts no matter how many darts you actually threw before you busted.
