Scoring

The standard dartboard is divided into 20 numbered sections, scoring from 1 to 20 points, by wires running from the small central circle to the outer circular wire. Circular wires within the outer wire subdivide each section into single, double and triple areas.

Various games can be played (and still are played informally) using the standard dartboard. However, in the official game, any dart landing inside the outer wire scores as follows:

• Hitting one of the large portions of each of the numbered sections, traditionally alternately colored black and white, scores the points value of that section.
• Hitting the thin inner portions of these sections, roughly halfway between the outer wire and the central circle colored red or green, scores triple the points value of that section.
• Hitting the thin outer portions of these sections, again colored red or green, scores double the points value of that section. The double-20 is often referred to as double-top, reflecting the 20's position on the dartboard.
• The central circle is divided into a green outer ring worth 25 points (known as "outer", "outer bull", or "iris") and a red or black inner circle (usually known as "bull", "inner bull" or "double bull"), worth 50 points. The term "bull’s-eye" can mean either the whole central part of the board or just the inner red/black section. The term "bull's ring" usually means just the green outer ring. The inner bull counts as a double when doubling in or out.
• Hitting outside the outer wire scores nothing.
