In the casual game play, the dealing of the hand in the game is rotated among the various players and this is marked by a buck or a dealer button. In a casino, where this game is played extensively, the house dealer has the right to handle the cards for each hand, but the button which is typically a white plastic disk is rotated in the clockwise direction among the players playing in order to determine a nominal dealer to determine the betting order. The dealer then shuffles the cards, the person sitting one hand right to him cuts the cards, and the dealer deals or gives the appropriate number of cards to the players. One or more players have to make a forced bet, which are blind bets or ante or sometimes both.  It is optional to give the cards face up or face down, which depends on the variation of poker which is being played. After the 1st round, the betting rounds begin. Between the rounds, the hands of players are dealt in certain ways, by dealing additional cards or replacing the previous ones.  At any time of the round, if one player bets and others choose not to call the bet, the hand is terminated immediately, the betting player is awarded the pot and no cards are required to be shown. At the end, all the bets are gathered into the central pot. This is made possible by bluffing, which is the main feature of poker. If at the end, more than one player remains, there is showdown, in which the player shows the hidden cards and evaluates their hands. The player with best hand wins the pot.
