Poker has many different varieties. It is a card game in which players compete to win as much money as possible. The highest hand wins the pot. The player with the best five-card hand wins the round. This continues until a player runs out of money, or until one player wins all of the money he or she put into the game as a buy-in.

The most common variety is Texas Hold’em. There are other variations, too, including Omaha, Razz, Seven Card Stud, Five-Card Draw, and more. Some variations incorporate elements from several different games to form a new game. The rules of poker differ for each of these games, but the basic principles remain the same.

The highest hand possible with a standard pack is a straight flush, which consists of five cards of the same suit. The highest straight flush is the royal straight flush, which is one of the highest hands in poker. However, the odds of obtaining a royal flush are one in nearly 650,000. The next best hand is four of a kind, which can contain any four cards.
