The game of
poker has many variations, most of them created in the
United States in the mid-1900s. The standard
order of play applies to most of these games, but to fully specify a poker game requires details about which
hand values are used, the number of betting rounds, and exactly what cards are dealt and what other actions are taken between rounds. Any game may also use any
betting structure.
They can be divided into the following groups:
- Draw poker: Games in which players are dealt a complete hand, hidden, and then improve it by replacing cards. The most common of these is Five-card draw.
- Stud poker: Games in which each player receives a combination of face-up cards and face-down cards in multiple betting rounds. The most common of these is Seven-card stud.
- Community card poker: Games in which each player's incomplete hidden hand is combined with shared face-up cards. The most common of these is Texas hold'em.
- Miscellaneous poker: Other games, or hybrids of the foregoing games.
