The rules of Poker vary according to the number of players. Unlike other casino games, Poker is not played by the dealer, but by one or more players. Each player has the privilege or obligation to make the first bet. In addition to the player who makes the first bet, every player who raises a bet has to place a chip in the kitty, equal to the total contribution of the player before him. A player who places a chip in the kitty is said to be an active player.

Among the possible hands, the best hand is the lowest one with four or more cards of the same rank, or two pairs. If a player has more than one five-card hand, the higher card wins. In some games, a player may have a pair of aces, which is the best possible hand. A pair of aces is also considered a high pair. There are various combinations of cards, but the most common is the two pairs.

The first round of betting takes place after a dealer reveals five cards face-up. Players then go around the table to determine whether to call or fold. Players may also shuffle their cards, but the dealer has the last right. If they are shuffled, they must offer the pack to an opponent for a cut. If they are not willing to make a cut, the dealer may shuffle the pack for them. The dealer has the option to make the final decision regarding who should raise the bet.
