Poker is a family of card games that combine gambling, strategy and skills. All poker options include betting as an essential part of the game and determine the winner of each team based on the combination of player cards, of which at least some of them remain hidden until the end of the hand. Poker games vary in number of dependent cards, total or community cards, number of remaining hidden cards and betting procedures.

In most modern poker games, the first betting round starts with one or more players who become a forced bet form (blind or ante). In standard poker, every player wins by category, I think their hand is valuable in comparison to other players. Then the action is clockwise, because each player in turn has either to match (or "call") the highest previous bet or to break, to lose the amount to build so far and to continue to participate. A player who fits a bet can also raise (raise) a bet. The betting cycle ends when all the players either call the last betting or fold. If all but one player has broken any circle, the remaining player collects the pot unnecessarily to reveal his hand. If there is more than one player left after the last betting round, a joke occurs when the hands are revealed and the player wins the pot with the winning hand.

With the exception of the first forced bets, the money is voluntarily placed in the pot only by those players who believe that the bet has a positive expected value or who is trying to bluff the other players for various strategic reasons. So while the outcome of any particular team significantly affects the odds, long-term players' expectations depend on their actions based on probability, psychology and game theory.

Since the early twentieth century, poker has gained popularity and initially was just a pastime for groups of small enthusiasts, dedicated to the widespread popularity of actors and viewers, including online, with many professional players and numerous dollars in tournament prizes.
