The game is played with 2 players sitting in alternate positions.
The first to play draws a card from the pile (leftover cards after dealing the cards), check out which combinations can be meld with it and the other cards and discards the one he/she doesn't want. This card starts the discard pile. After discarding, the turn goes to the player next to his/her left and so on, until someone ends the match. After each draw, the player is able to combine cards - meld - before discarding a card from his/her hand. Discarding means that he/she ended the turn and it's time for the next player to act. The player can't go back on decisions already made. From the second player up, there is the option to draw a card from the pile or all cards from the discard pile, in case they're not locked by the Black Three. But to do so, the player must justify the draw by melding the top card with other cards from the hand or playing it in a already played straight or suit. The player that knocks out with the initial 11 cards can go for the extra pile and continue to play. In a duos game, each extra pile corresponds to a team. If a team already draw the extra pile and goes out, the match ends but to do so, a Natural Canasta is needed. If the other team or player haven't draw the extra pile, 100 points is deducted from their total points in addtion to the points from the leftover cards. If there are any Red Threes and a canasta was meld, add up100 per Red Three. If there is no canasta it's 100 points less per Red Three.
At the end of the match, all points are summed up: the value of the card on the table plus the canasta values. If there are any Red Threes (and there is a canasta) add up 100 points for each on the table. If there are no canastas, subtract 100 points per Red Three. Then the value of the hand's leftover cards is deducted. The team that knocks out gets an extra 100 points, and if the other team didn't draw the extra pile they get a 100 penalty.
Detail: If a player draws the extra pile in a indirect knock out and the adversaries knock out for the second time (ending the game) before he can play the extra pile, another 100 points is deducted as penalty, like the team never draw the pile.
