Darts
A normal board is 17 and three-quarter inches in diameter and split into 20 sections, plus there are two circles in the middle, an outer ring and a triple ring (the ring halfway from the bull). Throwing the dart on the green ring (known as the "single bull") scores 25 points and the red spot (the "bull") scores 50 points. The 20 sections around the outside of the two circles each have a number from 1 to 20. The outer ring scores double the points and the triple ring scores triple. The highest score that can be made by throwing three darts in one round is 180. This is where all three darts hit the triple 20.
