Shanghai

Score big by hitting a single, double, and triple of the same number in one round.

How to play: Each round targets a specific number (1 through 7 or more). Score by hitting that round's number — singles, doubles, and trebles all count. A "Shanghai" — hitting a single, double, and triple of the same number in one round — wins the game instantly. If no Shanghai occurs, the player with the highest total score at the end wins.
