A poker game involves a fixed number of cards being dealt to each player. Each player then has the option to place a bet in the pot or fold. Generally, players make bets to increase the chances of making a strong hand or bluff. While a lot of the outcome of any given poker hand is determined by chance, maximizing winnings and minimizing losses requires skill based on probability, psychology and game theory.

There are many different games of poker, some more popular than others. Some of the more well-known varieties include straight poker, five-card stud, seven-card stud, lowball, Omaha, Cincinnati, Dr Pepper and Crazy Pineapple. While many of these variations are played in the same way, they differ in terms of card values and how the game is played.

Before the cards are dealt, players may have to contribute an ante or blind bet to start the game. Once the antes and blinds are in, the dealer shuffles the deck of cards and deals them out to each player one at a time, beginning with the person to their left. The dealer may deal the cards face up or down, depending on the variation of poker being played.

As each player gets their cards, the first of several betting rounds begins. Between each round, the poker hands develop in some way, either by receiving additional cards or replacing existing ones. Depending on the rules of the game, players can also exchange cards after the flop to improve their chances of getting a good poker hand.
