A round ends when any player has no cards left. That player is declared the winner of the round and is permitted to create a new rule for the next round. If a player has only one card left he or she must say "Bartok" or receive a penalty. This applies even if a player gets down to one card by non-standard means, such as trading hands with someone else. If the draw pile runs out before a round ends, all but the top card of the discard pile is flipped over to form the new draw pile. The game usually ends when several rules combine to make continued play impossible.
