Poker is a game of cards in which players wager money, or chips, over the quality of their hand. It can be played with 2 to 14 players, although the ideal number is six or seven. The object is to win the pot, which is the aggregate of all bets made in a single deal. This is accomplished by either having the highest-ranking hand, or by making a bet that no other player calls. Players may also bluff, betting that they have a superior hand when they do not, in order to induce their opponents to call their bet and concede the pot.
Most Poker games involve an ante or blind bet, which must be put in before the cards are dealt. The cards are typically dealt face up, but some games use a mix of both face up and face down cards. The cards are then gathered into a central pot, and the best Poker hands take the pot.
There are many variations of Poker, but all have at least one betting interval, and some have multiple rounds. The main skill in Poker is minimizing losses with poor hands and maximising wins with good ones.
A hand is composed of five cards and its value is in inverse proportion to its mathematical frequency; a rarer combination is ranked higher than a more common one. The ranking of a hand is determined by the rank of its highest card, which determines whether or not it beats another.
