The package includes a Big Blind, Little Blind, Missed Blind, Reserved, and Kill buttons. Each button measures approximately 1.2 inches in diameter.
Little, Big, and Missed Blind: Think of the Little and Big Blinds as the equivalent of an ante or forced bet, except only the first two players to the left of the dealer (clockwise) are forced into blinds. The first player to the left of the dealer is responsible for the Little Blind, which is usually 1/2 of the Big Blind. The second player to the left of the dealer is responsible for the Big Blind, which is usually 2 times the Little Blind. The size of these blinds are determined by the players in advance. The Little and Big Blind buttons will move one player to the left (clockwise), along with the Dealer Button, after each round of play. These two buttons, along with the Dealer, will always be in play on the table during Texas Hold'em
The Missed Blind Button is only assigned to a player that has missed any or all blinds. That player can resume play by either posting all the blinds missed or waiting for the big blind. If the player chooses to post the total amount of the blinds, an amount up to the size of the minimum opening bet is "live". The remainder is taken by the dealer to the center of the pot and is not part of the player's bet. When it is the player's next turn to act, they have the option to raise.
Kill: Any player who wins a pot is assigned the kill button. If that player wins a second consecutive pot then the wager amount is doubled for the next game only. This button can be used in many different Poker games. In Hold'em, usually the blinds are doubled for one game only
Reserved: Actually, this button is not related directly to Hold'em at all, it is simply used to hold a player's place at the table when the person is not present. It can be used in any card game.
