 The player who won the last hand becomes the new oya, and a new hand is dealt.Should both players ever run out of cards to play without having formed a yaku on the last play, the oya gains one point, and the next hand begins with the same oya (this is called "Oya-Ken", meaning "Dealer's Privilege").Generally, play continues for 12 hands, with each hand representing a month in the year, but the players can decide to play for a different number of rounds before the game starts.
