The player with the lowest score after a certain number of rounds or reaching a predetermined score threshold is typically declared the overall winner. The game continues for multiple rounds, and the scores are accumulated. The other players’ scores are determined by the total face value of the cards they still hold. The points are tallied, and the player who emptied their hand receives a lower score or no points.
