The objective of the game is to make more points than your opponent;
A game is played between two players in rounds;
Each player receives 11 cards, and two deads are set aside, both with 11 cards each;
Each at their own turn, the player starts drawing one card from the deck, or all cards from the pot. Then, the player can create new runs or add cards to existing runs. The player ends their turn by discarding a card to the pot;
If there is only one card in the pod, a player can still draw it, however they must discard a different card at the end of the turn;
A player can only change runs during their turn, and only after they drawed a card (either from deck or pot);
A player that has a single card at hand can't draw from the pot, they must draw from the deck;
A player goes out when they have no cards at hand;
The game ends when a player goes out and there isn't a dead available for them, or when the cards at the deck end and there are no more deads available.
A run must have at least three cards;
A run must have only sequential cards from the same suit, or all cards with the same number (same-number run);
A same-number run must have only A, K, or 3 cards, with mixed suits, and it is not allowed to mix number within the same run;
The valid sequence for the runs is: A, K, Q, J, 10, 9, 8, 7, 6, 5, 4, 3, 2, A. The A can be placed either at the begining or at the end of a run, and it must always be the first or last card (except in same-number runs);
The 2 card of each suit can be used as a wildcard, replacing any other card. Only one wildcard is allowed on each run, but it's possible to have a second 2 in the same run if it is being used in the place of the 2 card (with the correct suit);
A wildcard can be used in a same-number run, even to create it (i.e.: K, K, 2);
It is not allowed to remove cards from a run. It is legal to reorder them within a run (often the A or 2) if the sequence stays valid;
A run that has seven or more cards is called a canastra. A canastra can be dirty (with wildcard) or clean (without wildcard). A 2 in the two's position doesn't render the canastra dirty if there is not another wildcard in the run;
A run with 14 cards, from A à A, without wildcards, is called canastra real;
A same-number run can be a canastra, both dirty and clean.
A game starts with two deads, with 11 cards each;
When a player goes out the first time, and there is a dead available for them, the player receives a dead and keeps playing;
Each player can only receive one dead during the game. If the player goes out after having received a dead, the game ends;
If the deck goes out of cards, a dead is moved to the deck at the end of the current player's turn (after they discard);
The deads aren't assigned and don't have any priority. A player that goes out gets the first dead available, and if the deck has no cards the first dead available is moved to the deck. In this setup, it is possible that a player goes out and the game ends.
When the game ends, points are calculated and the player with the most points wins;
If the game ended because a player has gone out, this player gets 100 points;
Each card in each run is worth 10 points;
Each canastra at the table is worth 200 points (dirty), 300 points (clean) or 1000 points (real);
If the game ends because a player has gone out, the opponent loses 10 points for each card they have left in their hand.
