There are five betting rounds, one after each round of face up cards and one after the final card is dealt. The deal is as in seven card stud: two cards face down, four face up and the last face down. Because of the extra cards dealt after fours, this game cannot be played by more than six people without the risk of running out of cards. The numbers are chosen because of their significance in the American sport - three strikes, three outs, nine innings, four balls for a walk. All threes and nines are wild and fours give the player an extra card.
Baseball is a popular home poker variant based on seven card stud.
