Poker is a card game in which players bet money into a central pot based on the strength of their poker hand. The winner is the player who holds the best poker hand. A poker hand consists of five cards, ranking from Ace to King (though sometimes aces are treated as high).

The game is played with a standard pack of 52 cards. Some variants use more than one pack and add a few cards called jokers.

In the first round of play, each active player receives one faceup card and one facedown hole card. In the second and third rounds, a betting interval is followed by a showdown, in which the players’ hole cards are shown.

Once all players have had a chance to bet, raise or fold the dealer deals three cards to the community. These are “flop” or community cards that anyone can use to make their hand.

After that, the dealer puts a fifth community card on the board which is known as the River. After that, everyone gets another chance to bet or raise if they want.

Once the final round of betting is over, the dealer reveals the cards and the player who has the highest poker hand wins the pot. This can be a good or bad thing depending on what cards you are holding and how many other players are still left in the hand.
