Poker is a gambling game where players bet on the value of their cards. The winner of each round takes the entire pot, unless the hand is a draw.

There are many variations of poker. In most, each player puts an ante into the pot before they are dealt their cards. The ante is a contribution that prevents the game from going too long and keeps each player somewhat invested in each round.

The ante is not mandatory, however, and players who do not want to put an ante into the pot can discard their cards and are out of the game. The amount of the ante is determined by the rules of the particular variant being played.

Betting is the most important aspect of Poker, as it is the key to the outcome of the game. In each betting interval, a player may call (put into the pot the same number of chips as the last bet), raise, or fold.

Raise: To raise, a player must bet more than the previous call. They can do so by betting an amount that is equal to the difference between the amount of their last bet and the amount that they have been raised since their last bet.

The highest possible hand in Poker is the Royal flush, which contains ace, king, queen, jack, and ten of one suit. It can also be made with two aces and three of another suit, such as ace, king, queen, a jack, a ten, and a ten.
