Three-Thirteen Rummy is a card game where players aim to form Melds of 3+ cards by drawing and discarding. Melds can be Sets of 3 or more cards of the same number, or Runs of 3 or more cards in the same suit. You play against three computerized Opponents - Left, Top, and Right.

The game uses two combined decks of standard playing cards totaling 104 cards. Optionally, two or four wildcard Jokers can be added for a faster pace. Rounds progress with dealing cards, drawing from the deck or discard stack, utilizing wildcards strategically, forming Melds, and tallying points at the end of each Round.
