Poker is a card game where players bet money into a pot and try to get the best 5-card hand. The winner of a round wins the entire pot.
The game starts with each player being dealt two cards face down (hidden from the other players). The player to the left of the big blind is the first to act, i.e., fold, call the big blind, or raise his own bet.
Next, the dealer burns one card from the top of the deck and deals 3 community cards (the flop) face up to the table. These are community cards, and each player may use them to build his or her best 5-card hand.
After the flop betting phase, a new round of antes and blinds begins. After the ante and blinds are resolved, each player takes turns revealing their cards.
In poker, each hand is valued inversely to its mathematical frequency, so the higher the hand rank, the more likely it is to win. The highest valid hand is a Royal Flush, which consists of an Ace, King, Queen, Jack, and 10 all from the same suit.
The game of poker is played in hundreds of variations, but most include some form of betting interval. The standard straight, for example, consists of five cards in a row of consecutive rank and suits from the same deck.
