Shanghai is a fun and easy game to learn and is good for practice as well because it covers the whole board. Players take turns throwing at the numbers from 1 to 20 (or 1 to 7 in some variations), in sequence. Only darts hitting the target number in that round count for score.
There are two ways to win: either have the highest score at the end of the game or get a Shanghai and win immediately regardless of the other players’ score.
To Shanghai, you must hit one dart in the single, one in the triple and one in the double of the target number in any order.
If you hit a double or a triple with the first dart, always try for the Shanghai. If you miss it, you will still have a decent score and if you do get it, you win.
