Mexican Canasta is played the same as regular Canasta except for:
- Three decks with 6 jokers are used.
- Each player is dealt 13 cards. Whenever a player makes the initial meld for his side, he draws 13 cards from the stock and adds them to his hand.
- The discard pile may not be taken when the top card is a 7. Sevens are melded as usual and a canasta of sevens (mixed or natural) counts as 1000 points.
- In order to go out, a side must have two canastas, and at least as many red threes as it has canastas.
