MAKE ALL TABLES DRAW 2 CARDS, 1 CANASTA, RATED, PRIVATE.
If your opponent canastas 4s, you can only canasta 5s or higher. Melding anything is fine, you can both have the same cards melded, but each canastas must be at least ONE BETTER than the last one. You can make more canastas on your turn, but they must be higher than the last one you made. When Aces have been put to a canasta no more canastas can be made by either player. You may NOT pick up the pile, but you can go out anytime.
