Thus there are 11 points to be won in each round if there are no sweeps scored and there is not a tie for number of cards. Typically, when at least one player has reached a score of 21 or more at the end of a round, the winner is the player to score the highest after tallying points. In one two-player variation, a player can call for a game to be concluded once they are convinced they hold sufficient cards to bring their score to 21; if they do have 21 points, they win regardless of their adversary's score; if they do not have 21 points, their adversary wins. If one player has won the entire 11 points, some rules state that this player will be awarded an extra point for 12 total points in the round. Other rules state that this is a "skunk" if it occurs in the first round, and therefore that player wins. In other variations, taking all traditional 11 points in a single round is an automatic win, no matter when it occurs. Three players in the game can share 11 points and one must lose with fewer points out of 11 points; this is a perfect balancing. A sweep is declared by a player who manages to capture all face-up cards from the table. In some localities, each sweep is worth an additional point. The opponent has no move except to trail, and a follow-on sweep may result. Points for sweeps are awarded after the base 11 points, in the event that two players reach 21 in the same round. In another variation, trailing the five of spades sweeps the table, the sweep giving one point. There is a variation in which sweeps are scored as they occur; if the sweeper had 20 points (or more, due to a tie score), the sweep would end the round instantly. A scoring variation in which each point card is scored as it is captured also exists. In a variation devised in Michigan, a player who defaults on his duty after building gives up 2 points at the time of the violation. This is sometimes an acceptable cost to trap cards from the other player in builds the player cannot take. Sweeps also score 2 points. In a series of "rounds to 5," any three instant scores (sweeps or defaults) against the same player ends the round. These sudden-death variations make short-term tactics more important in certain situations than the longer-term goal of achieving the high score for the round. In some regions, all four face-cards of the same rank may be gathered simultaneously. This allows natural building with face-cards, while still removing the possibility of an "orphan" card.
