Seven-card melds is a card game that is similar to the popular game of Canasta. It is played with two to four players and requires seven cards to be melded in order to win. The goal of the game is to create melds, which are sets of three or more cards of the same rank, and then lay them down on the table. The player with the most melds at the end of the game wins. Canastas is a variation of Seven-card melds where the player must create melds of seven cards in order to win.
