Poker is a family of card games in which players wager on what hand is the best based on the game’s rules in ways similar to these rankings. Originally played with just 20 cards, the game is played nowadays with a standard deck.
There are many different variations of Poker, but all have the same goal at the end of the day. The goal is to end with the best five-card hand possible.

The first betting round in most modern poker games involves one or more players making something of a forced wager (the blind or ante). Each player bets according to how much they believe their hand is worth compared to the other players. Each player then has the option of matching (or “calling”) the previous maximum bet or folding, losing the amount previously bet and all further involvement in the hand.
In addition to matching a bet, a player can also “raise” it. All bets end when all players either call or fold the last bet. Suppose all players except one fold, the remaining player collects the pot without being required to reveal their hand. After the final betting round, if there is more than one entrant, a showdown occurs, and the winning hand is revealed.
A player puts money into the pot if he believes it has a positive expected value or is trying to bluff the other player for some strategic reason. While the outcome of any given hand is greatly affected by chance, the long-term expectations of the players are determined by the actions they take based on probability, psychology, and game theory.
From a hobby confined to small groups of enthusiasts at the beginning of the 20th century, Poker has become a widespread activity, both for participants and spectators, including online, attracting many professional players and multimillion-dollar tournament prizes.
