What is the name of the dartboard game in which players must hit 1 through 20 in sequence?

Around the Clock is the dartboard game in which players aim to hit the numbers from 1 through 20 in sequence.

A player normally begins by targeting 1 and moves to the next number after hitting it. The game can then finish with the outer bull and bullseye, depending on the agreed rules. It is widely used as a practice exercise because it encourages players to throw at every sector rather than concentrating only on treble 20.

Rules vary in casual play. Some versions require a single hit to advance, while others require doubles or trebles. Players may also decide whether the bull counts as the final target and whether missed targets allow unlimited attempts.

Around the Clock should not be confused with Cricket, which uses selected numbers and scoring marks, or Shanghai, which commonly involves rounds for a number and its single, double, and treble.
