Each player receives 2 cards, called their hole cards. A round of betting follows. The first player to the left places chips in the pot (representing money, as opposed to real money) equal to the total amount of bets placed by all players before him. A player may choose to call, raise, or fold.

After the flop, one more card is dealt face up. A second round of betting starts with the player to the left. A player can also check, meaning they do not want to place any bets.

The highest pair of cards wins. If the high hands are the same, then ties are broken by the high unmatched card. If the high unmatched card is a suit, then ties are broken by the higher rank of that suit.
