Poker is a card game with many different variations, each involving betting on the outcome of a hand. Some forms of the game involve only two players; others can include up to 14 players. It is often played using a single deck of 52 cards.

The objective is to win the pot – all of the bets placed during one round. This can be achieved either by having the highest ranked poker hand when the hands are revealed or by continuing to bet that your hand is better than the other players’ until they drop out of the betting process.

Players make forced bets at the start of a hand, which are known as “initialized bets” or “pre-flop bets”. There may then be several rounds of betting. A player’s hand develops during these rounds by receiving additional cards or replacement cards. In addition to the initialized bets, each player may also place bluff bets during a hand.

A high card hand wins a round. In the event of a tie, the highest unmatched card is shared. A straight has five consecutive cards of the same suit, beginning with the ace. Three of a kind is the same rank, but not the same suit. A flush is five matching cards of the same suit.

During a hand, if a player calls the previous raise, they will match that bet. To call, you must say “I call” or something similar and then place the amount of your bet into the pot.
