A person who is not actively participating in the actual game is used to deal the card hands when button games of poker are in play. The term “button” refers to a circular disk that is used as a marker to denote who it is in the game that is serving in the capacity of the dealer. The person who is acting as the dealer in the game gets the cards on the primary round of the game only after every one else in the game has already received the cards. Also, the person who acts as the dealer reserves the power to make the final move of the round after the primary round has come into play. During the course of the game, the button is rotated around the table so that all the 
players get a chance to act as the dealer. The button is sent around the table in a clockwise motion with the closing of each deal hand. This way, each of the players in the game receive a chance to act as the dealer at least once during the game, and by doing so they are able to enjoy the benefit of being able to take the last call on the round before the round closes.
Blinds are moves that are made with the betting process in order to begin the actual play in the rounds. Placement of the blinds is done prior to the players actually getting a chance to see the cards they have been dealt. In most games the blinds themselves are included into the game as a component of the bet placed by the player. However, there are some games in which the framework of the game is such that it calls for the use of blinds to be made invalid. In such games a specific category of the blind or even all of the blinds are declared to be “dead” and thus cannot be used to play in the game.
Since it is mandatory for all the players to receive a chance to use the button, the button is moved forward along the table. When this happens, the button is known as the “moving button” and the blinds in play on the table are altered in accordance with the movement of the button.
There are some cases in which the button is declared to be a “dead button”. When this is the case a player who is expected to move at that time is obligated to place a big blind.
