Poker is a family of card games in which players try to win by making the best hand possible from the cards in their hand. The game is played with a standard 52-card deck. Depending on the variant, a player’s hand may be ranked based on odds, or it may not.

All poker variations involve a round of betting. Players are required to bet or raise a certain amount in each round. If they do not, the round ends. At the end of the round, the bets are accumulated in a central pot. This pot can be won by the highest-ranking hand, or by a player making a bet that no other player calls.

Each player is dealt five cards, unless a “wild” card is included in the deck. These wild cards are used to create the highest possible hand. A wild card can be used to make a straight or a flush.

Usually, the dealer deals the cards to each player clockwise. The dealer button is a white plastic disk. It indicates the nominal dealer, and determines the order of betting.

Each player can then shuffle their own cards or take new cards from the top of the deck. Cards are usually dealt face-down, but may be dealt face-up.

In most modern poker games, a forced bet is required. This is often referred to as the ante. There are several types of forced bets. Some are blind bets, which are made by players without any visible indication of the bet, and others are a forced bet, which is made by a player before the other players know what he is betting.
