Poker is a family of card games in which players wager over which hand is best. It is played around the world and has various variants. Each game has its own rules, but all have the same goal: to create the best possible hand by combining cards.
The standard pack of cards used in most poker games is 52 cards, but a few jokers may also be added to make it more exciting. The cards are ranked from high to low (Ace, King, Queen, Jack, 10, 9, 8, 7, 6, 5, 4, 3, 2, Ace) and are of four suits (spades, hearts, diamonds, clubs).
A straight is a hand of five cards that is the same suit; a flush is a hand of six cards that is of the same suit. The highest natural hand is a Royal Flush, which is five cards of the same suit with an Ace high.
When betting, players are required to place an ante, which is a fixed amount of money that must be put into the pot before any cards are dealt. In addition, a player can bet an all-in amount, which is when the player puts in all of his chips into the pot.
Players choose to play at different stakes on the basis of their perceived skill level. Better players are more likely to bet at higher stakes, while worse or beginning players may play at lower stakes.
