Poker is a card game for two or more players, played in rounds with betting between each round. The object is to form a winning poker hand based on the rank of your cards and win the pot, which is the sum of all bets placed throughout a deal. You can win the pot by having a high-ranking poker hand at the end of the betting round or by placing bets that no other player calls, leading them to fold their cards.
A poker hand is a group of five cards. A pair is two identical cards of the same rank. Three of a kind is three matching cards of the same rank. A flush is five consecutive cards of the same suit. A straight is five cards in order of rank but from more than one suit. A full house is three matching cards of one rank and two matching cards of another rank. High card is the highest single card and breaks ties.
To begin a hand, each player must make a bet, as determined by the rules of the particular poker variant being played. This bet is usually made by placing chips (representing money, for which poker is almost always played) into the pot.
When it is your turn, you can Check if you do not want to bet more than the player before you or Raise if you want to increase your bet size. You may also Fold if you do not wish to play the hand.
