Poker variant


The card game of poker has many variations, most of which were 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.

The three most popular poker variants are spread in casinos and poker rooms worldwide and can be divided into the following groups:

Here are more common rule variations:

Poker can be played in a mixed game format, for example one half-hour of Texas hold 'em followed by one half-hour of Seven-card stud. There are many types of mixed poker games. The most notable mixed poker variation is H.O.R.S.E. poker. H.O.R.S.E. is a mix of Texas hold 'em, Omaha high-low, Razz, Seven-card stud and Seven Card Stud Eight-or-better. Each game will usually be played for a fixed number of hands or time and then the players will move on to the next game.

Other mixed games include:

Some poker games don't fit neatly into the above categories, and some have features of more than one of these categories. These variants are most often played in home games, usually as part of a dealer's choice format.

Stud Horse poker was banned by California statute Section 330 in 1885, although no definition was given. In 1947, the attorney general of California ruled that stud horse poker was the same game as stud poker, and later the restriction on stud horse poker was removed.

Though called "stud", this is a combination stud/community card game that was popular at MIT in the 1960s, in which players receive individual downcards, individual upcards, and community cards. Many variations on this are possible by changing what kinds of cards and how many are dealt in various rounds.

One difficulty with such a combination is deciding the betting order: in stud games, the player with the best upcards showing bets first in each round (except sometimes the first, where the worst upcard is forced to begin the betting with a Bring-in). In community card games, each betting round begins with the same player (because there generally are no upcards), making it more positional. Oxford stud chooses to use the players' individual upcards for determining order, which makes it play more like stud.
