I made a crib sheet to help remember the requirements of each hand (see below). As we played the game trying out different rules I decided to consolidate on one set of rules. There were several sites that gave slightly different rules, and they called the game Shanghai Rummy. However, we couldn’t remember the exact rules so I looked them up on the internet. It’s a card game I first learned back in the 1960s.
We recently decided to play Shanghai when my sister came to visit.
