The winning team is determined by the total number of cards held by that team when the one player runs out of card. If one player plays his last card but his teammate has more cards left than the other team's total, his team loses. (Ex: Mike and Dave are on one team against Lionel and Brendan. Mike has 4 cards, Dave has 5, Lionel has 10 and Brendan has 1. Brendan plays his last card but Lionel has 10 cards and Mike and Dave have 9 cards total. By playing his last card Brendan has lost the game for his team.) Any player can ask what the card count is for each team at any point.
