Texas hold 'em is the most popular of the community card poker games. It is the most popular poker variant played in casinos in the western United States, and its no limit form is used in the final event of the World Series of Poker , widely recognized as the world championship of the game. It is commonly played in the rest of the world as well, but Seven-card stud and other local games may be more popular in some places. Although it can theoretically be played by up to 23 players, it is generally played by between 2 and 10 players. It is one of the most positional of all poker variants, since the order of betting is fixed.
