Poker is a card game in which players wager money on the outcome of a hand. The game is played in betting intervals, or rounds, with each player in turn having the option to call, raise, or fold. The player who has the best hand wins the pot.
There are many different variants of the game, but most share some common features. The most important is the fact that each player has five cards to work with: two in their hand and the other four on the table. A hand is worth more if it contains more cards.
In addition, a hand’s value is inversely proportional to its frequency, so the more unusual a hand is, the higher it ranks. Ties are broken by the highest unmatched cards or secondary pairs (in the case of a full house).
