Seven-card stud, also known as Seven-Toed Pete or Down-The-River is a variant of stud poker. Until the recent increase in popularity of Texas hold 'em, seven-card stud was the most widely played poker variant in home games across the United States, and in casinos in the eastern part of the country. Two to eight players is common, though eight may require special rules for the last cards dealt if no players fold. With experienced players who fold often, even playing with nine players is possible.
In casino play, it is common to use a small ante and bring-in. In home games, it is typical to use an ante only.
Seven-card stud is the "S" game in HORSE and similar mixed game formats.
