if three darts are thrown at the dart board and no darts hits a line what score is possible?

I am not a dart player, but I hope the following article helps you.

To determine the possible scores when no darts hit a line on a dart board, we first need to understand the scoring system used in most dart games.

A standard dart board is divided into 20 numbered sections, each with a different point value ranging from 1 to 20. These sections are organized in a circular arrangement, with the highest scoring section (20) at the top and lower-scoring sections moving clockwise towards the center.

The dart board also features two additional concentric circles, called the inner and outer bullseye. The inner bullseye is worth 50 points, while the outer bullseye is worth 25 points.

In your question, you mentioned that no darts hit a line on the dart board. Usually, this implies that all three darts missed the board entirely. In such a scenario, the score would be zero.

Therefore, if three darts are thrown, and none of them hit a line or the board, the resulting score is 0.
