Poker is a card game that involves betting between two or more players. It is played with a standard 52-card English deck and can be modified to include wild cards. It is played both casually and professionally. It has become one of the most popular games in the world.

Depending on the rules of the variant of poker being played, one or more players are required to place an initial amount of money into the pot before the cards are dealt. These are known as forced bets and are generally either an ante or a blind bet (or both).

After the antes and/or blinds have been placed, the dealer shuffles the cards and the player on their chair cuts. The dealer then deals each player two cards, face-up or face-down (again, depending on the rules of the game). After the first deal, the first of several betting rounds begins. During each round, players develop their hands by adding to or replacing the cards they already have. At the end of each round, all bets are gathered into the central pot.

When all of the bets have been made, the players reveal their hands and the player with the best five-card hand wins the pot. If no player has a winning hand, the pot is shared among the players who had a high-ranked hand in that round. Occasionally, there will be a tie between two or more players with the best 5-card hand.
