Frequently asked questions
What is an online dart scorer?
An online dart scorer subtracts each turn from a player's 301 or 501 total and tracks whose turn, legs, sets, and averages automatically.
How does double-out work in darts?
To win a leg, the final dart must land in a double segment or the inner Bull. Reaching zero on a single or triple is a bust.
What causes a bust in 301 or 501?
A turn busts if the score passes zero, leaves exactly one, or reaches zero without a double. The player's score returns to its value before that turn.
How is a three-dart average calculated?
The scorer divides total points scored by darts thrown and multiplies by three. Bust turns add darts but no scored points.
