Poker is a card game that has evolved over centuries. The game can be played with any number of players, but the ideal number is between six and eight. All players in the hand must bet to form a poker hand, and the highest hand wins the pot. Poker can also be bluffed, with players betting they have the best hand and hoping the other players will match the bet.

The dealer is the person who deals out the cards. In casual play, this person rotates among the players. The dealer button is a white plastic disk that marks the nominal dealer. The dealer deals cards to each player clockwise around the table. The player who is high at the end of the hand will initiate the action for the next round.

In seven-card stud, the player receives two downcards and one upcard before the first betting round. Each player then has one betting round after each upcard. The player with the best five-card poker hand wins the pot. The first two betting rounds are the smaller bets, while the third, fourth, and fifth betting rounds are the larger bets. The final betting round is called the showdown.

In all of these variations, each player must ante a certain amount before betting. They then bet their chips into the pot in the center. The player with the highest hand wins the pot. The betting is done in a clockwise fashion, until each player has called or folded.
