Poker is a game of cards played worldwide. Although poker games vary in the number of cards in play, the betting structure, and the deck configuration, they are generally based on the same basic rules. Players make bets on their hands and a showdown is held when the best hand wins the pot.
The first poker games were probably played with a 20-card deck. During the American Civil War, stud poker was introduced. After 1875, a 52-card deck was used and a wild card was added. Today, most poker games use a standard deck.
Some poker variations do not consider flushes and straights. A high card can be a lima sama kartu (sepasang kartu) or a nilai sama kartu (makna sama).
A common feature of poker is bluffing. For instance, the player may bet a specific amount of money, raise the previous bet, or place a forced bet, also known as a blind bet. These actions are based on game theory and psychology.
In most games, players bet in one round. Usually, this round is based on the ranking of the highest hand, but some games do not. Other games involve several rounds of betting. Depending on the variation, players are usually able to discard some of their cards.
Cards are dealt clockwise around the poker table. Five-card hands are often dealt face-up. One or more cards are discarded, and the remaining players bet. All but one player folds.
Poker is usually played with chips. These are normally ceramic or plastic. They are easy to handle.
