Gin Rummy is the classic card game made for the online multiplayer Plato platform. Players use the cards in their hands to form sets and run to score points and outplay their opponents.

The game was out of date and needed to be converted from JavaScript to TypeScript by hand so that it could make use of newer Plato APIs and libraries. I also programmed a universal card back system so that IAP card backs could be used in this game and any other Plato card games that made use of a standard 52 card deck.
