It's a 2 players game, where they sit in opposite positions.
Definitions
The first to play draws a card from the pack, checks all possible combination at his/her hands and throws away one that doesn't interest him/her. This card starts the discard pile and only the top card from it can be seen. After discarding, the next player goes, and so on, until the match ends. After each draw, the player can combine some cards - meld - before discarding one from his/her. Discarding means that this player ended playing for now and is passing the turn. The player can't go back. From the second play and on, there is the option to draw a card from the pack or all cards at the discard pile. But someone can only draw the discard pile if the card from the top of it melds into a game already at the table or with the cards in hands The player that knocks out with the initial 11 cards can draw the extra pile and continue playing. If a player that already draw the extra pile goes out again, the match is over, but to do this at least a natural canasta is needed. If any player isn't able to draw the extra hand, a hundred points must be discounted, plus the points for each card left in hand. In case the pack of cards end before the match ends, and there is still an extra hand, this extra pile must be moved to the pack and the game continues.
By the end of the game, all points are summed. Cards over the table plus the canasta values. Then all the points from the cards left on your hand are discounted. For the player that knocks out, there is an extra hundred points. For the ones that didn't draw the extra pile, a hundred points are discounted.
Detail: If a player draws the extra pile throught an indirect knock out and the adversary ends the match before the player uses the extra hand, the points must be discounted, like the player never got the extra hand.
