Poker is a card game that involves betting. It is a skill-based game that also involves psychology. It is played between two to 14 players. Each player competes to win the pot, which is the sum of all bets made in a single deal. There are many different forms of the game, but most involve betting in rounds with raising and re-raising allowed.
A standard 52-card deck is used. Some games add jokers or other wild cards to the mix. Most poker games have a dealer, who is responsible for shuffling the deck and dealing it to each player. The dealer is also responsible for establishing certain betting rules. A dealer chip is passed around the table to designate who will be the dealer for a given round. In some games a non-player may be assigned the role of dealer.
In most poker games players place a small bet called an ante before their hands are dealt. Some games require a blind bet, which occurs in addition to the ante.
The dealers deals a third card face up on the board, which is available to all players. This is called the flop. Then he deals a fourth card face up, which is again available to all players.
After the flop is revealed the remaining players either call the raise, fold, or check (a player must call the amount of any bet in order to stay in the hand). If there is no all-in before the last betting round then the pot is awarded to the highest ranking poker hand.
