Play starts with the player to the left of the dealer and move to the left. When it is his turn, a player asks the player on his right for a card with a specific difference. For example, he may say, “Give me a 6,” or “Give me an 11.” If the player who is asked has such a card, he must give it to the player who asked for it. If the asked player does not have such a card, then the player who asked takes a card from the deck. In either case, if pairs are formed, they are shown and discarded. The first players to run out of cards is the winner. Notice that it is possible for two players to tie, if they both run out of cards on the same play.
