Yahoo! Games Canasta
Yahoo! Games Canasta offers both four-player and two-player games, using two standard 52-card decks and four jokers combined to make a 108-card deck. The object is to be the first to score 5,000 points by melding sets of three or more cards of the same rank. Shuffling, dealing, and scoring are handled automatically. Game rooms are provided for social, beginner, intermediate, and advanced players. Requires a Java-capable browser.
