Please study the dart scoring diagram above.
Each player throws 3 darts. After you count the first player's score, that player removes the darts and the next player throws 3 darts.
If you throw a dart into the outside ring, where the numbers are, that dart doesn't get any score.
Let's think of the dartboard as a wagon wheel and each of the spokes is "V" shaped. Each of these "V" shaped spokes has a point value from 1 to 20, which is shown on the outside edge of the dartboard. Also, different areas of each "V" spoke are worth different points, depending on how close to the middle of the dartboard you get.
The white sections of the "V" spoke count for whatever the number is on the outside edge (single area). The smallest section of the "V" spoke, closest to the number ring, counts as double the number (double ring). So if you hit the 6 spoke in that small area, you get 12 points. If you were to put all three of your darts in that same space, you would have 36 points.
The small section of the "V" spoke closest to the bull's eye is called the (triple ring). So each dart counts as triple the number on the spoke. Therefore, in the above example, you would score 18 points for one dart and 54 points for 3 darts, in this section.
As you look at the bull's eye, it has a green outer ring (single bull - worth 25 points) and a red inner dot (double bull - worth 50 points). If you threw 3 darts into the double bull, you would score 150 points. Now, if you threw 3 darts into the triple ring on the 20 "V" spoke, you would score the highest possible - - 180 points.
As you can see, the bull's eye is not the main object.
