Poker is a card game that involves betting and the use of cards to create winning hand combinations. The game has several variations, but the basic rules apply to most of them.

The first step in any poker deal is for the dealer to shuffle the cards and to cut off the deck. The dealer deals the cards one at a time, beginning with the player to his left. Then the first of what may be several betting rounds begins.

Each betting round involves players placing bets in the central pot, which is the sum of all bets placed by all players. The bets may be placed directly into the pot, or they can be thrown into a small box (or “splash”) that is located in front of the pot.

When a bet is made, the current bet amount must be at least equal to the total bet amount of the player who placed it last in the previous round. The bets are gathered together at the end of each betting round, and the player who made the highest-ranking poker combination wins the pot.

The ranking of standard poker hands is determined by odds and probability, and in some games two or more identical hands tie and divide winning equally. The rank of poker hands is often altered by the presence of a wild card or by the addition of a flush or straight.
