Razz is seven-card stud played for low only, using ace-to-five ranking. In the first betting round the compulsory bring-in bet is made by the owner of the highest card showing.

In subsequent rounds, from fourth street onwards, the lowest hand showing bets first. Ace is low and king high throughout, and as usual the suit of the highest card is used to break ties, so if on fourth street two players tie for lowest with 6-2 and 6-2 the second hand will start the betting, because the six of clubs is lower than the diamond.

In fixed-limit games the limits double at fifth street: on third and fourth street only small bets are allowed, and from fifth street onwards only big bets. Pairs showing have no effect on the size of bets.
