Poker is a card game played by two or more players. Typically, players use two decks of 52 cards, one of which has a different back color than the other. In some variations, wild cards may be included in the deck. Using these cards can help players complete their hand by supplementing one or more of their other cards. The number of players playing poker depends on the number of people in the room.
Each player in a poker game has a certain number of poker chips. This number varies in different games, but for a game with seven or more players, a supply of at least 200 chips is necessary. In general, the lowest-value chip is the white one. Other chips, such as red or blue, are worth five, ten, or twenty. In addition, there are also dark-colored chips, which are worth two, four, or five reds. The dealer usually assigns a value to each chip before the game begins.
In some variations, players may have to contribute to the pot before the dealer deals the cards. This is known as the opening bet. The player who opens the pot must show a hand that is Jacks-or-better. Other cards in the hand may be hidden.
