What is a “Shanghai” finish in darts?

A Shanghai finish in darts is a single, double and treble of the same number in one visit.

For example, a Shanghai on 20 consists of single 20, double 20 and treble 20, producing 120 points. The term can describe the combination itself, and in some games it is especially significant when the player is finishing a leg or completing a designated target.

The name is commonly associated with the game Shanghai, in which players throw at numbers in sequence and score through singles, doubles and trebles. Rules for Shanghai vary between casual and competitive formats, so the exact winning condition should be agreed before play.

A Shanghai is different from a maximum: three treble 20s score 180, while a Shanghai uses three different bed values on one number. It is also distinct from a checkout, which must reduce a player’s remaining score to exactly zero under the game’s rules.
