Poker is a card game in which players place bets against one another. The object of the game is to win the pot, or the sum of all bets placed during a hand. The cards are dealt in a single round of betting, with raising and re-raising permitted. Players may also bluff, or bet that they have the best hand, in an attempt to discourage other players from calling their bets.

Poker can be played by two to fourteen players. The game has a great deal of luck and complexity, but it also requires some degree of skill and psychology. Players with the highest skill levels usually perform better than those with less-developed skills, although there are some exceptions.

Typical poker games award the pot to the highest-ranked hand, with the remaining hands splitting any winnings equally. However, there are many different variations of the game, with some treating suits differently and others allowing for wild cards. In the latter case, the highest-ranking hand is a royal flush (five consecutively ranked cards of the same suit), while the lowest is a pair of aces.

The player in position to act last is known as the “big blind” or “big boy.” The players seated to his left are known as the “under the gun,” or UTG. The seat to his right is the “cutoff,” or CO. The next seats are the “button,” or BTN, and then the “small blind” or SB.
