Poker is a card game in which players make bets that other players must either call or fold. Players can also bluff in order to try to win the pot, or all the bets made during a hand.

There are a number of different poker games, and each has its own rules and betting structure. However, all poker games share some basic principles. The most important is that the highest ranked poker hand wins. Each poker hand consists of five cards. Each card has a rank (Ace, King, Queen, Jack and 10 are low) and a suit (spades, hearts, diamonds and clubs). Some poker variants may have wild cards or other special cards.

After each player receives their 2 hole cards, there is a round of betting initiated by 2 mandatory bets called blinds put in by the two players to the left of the dealer. A fourth card is then dealt face up, this is called the turn. The final betting round will reveal the fifth and last community card called the river.

At this point the players should decide if they want to continue to play their hand. If they do they will reveal their cards and the player with the highest ranked hand wins the pot/all bets made during that hand.
