The game of poker involves the drawing of cards. The hand with the highest card wins. In some variants, one or more packs of cards are used, or jokers are added to the deck. The four standard poker hands are: King, Queen, Jack, and Ace. The Ace is the highest-ranking card, and it can be high or low, or both. There are four suits to the cards, and each suit has its own relative rank. A poker hand always has at least five cards. There are also variations in the game that include a Wild Card, which may take any suit but cannot be high.
There are countless variations of the game of Poker, which are played online and in casinos. In many cases, the variations are the same, but the rules differ from one another. For example, if there are ten players, two separate games may be organized. These variations are all described later in this chapter. In addition, the number of cards dealt decreases the chance of luck, but the expected value remains a bell-shaped curve.
In some variants, the game of poker involves betting. Players must place an ante, which varies depending on the type of game. They then place a bet into the pot in the middle, and the player with the best hand wins the pot. The betting rounds proceed in clockwise order, until all players call or fold.
