In most variations of poker, each player is dealt a hand of cards, and the goal is to create the highest-ranking hand according to a set of rules. The ranking of poker hands typically follows a hierarchy, with the highest-ranking hand being the royal flush (a straight flush including the Ace, King, Queen, Jack, and Ten of the same suit) and the lowest-ranking hand being a high card (a hand that does not contain any pairs or ranked combinations).

Players take turns betting on the value of their hands, and the goal is to win the pot, which is the total amount of money or chips that have been bet by all of the players. Players can win the pot by having the highest-ranking hand at showdown or by convincing the other players to fold (give up) their hands, sometimes by bluffing (pretending to have a stronger hand than they actually do).

The games are usually played in casinos, poker rooms, online, or in home games.
