The highest possible checkout in darts is 170. It is finished by hitting treble 20, treble 20 and bullseye.

In most common darts formats, such as 501, the rules require a player to finish on a double. This means the final dart must land in one of the double segments or in the bullseye.

A preferred double is the double a player feels most confident finishing on. Common preferred doubles include double 20, double 16, double 10 and double 8.

Bogey numbers are scores that cannot be finished in three darts, even though they are below 170. Examples include 169, 168, 166, 165, 163, 162 and 159.
