'D' indicates the dealer player who virtually distributes the cards. During the toss, the player who gets the lowest face value card is the dealer and he or she distributes the cards and always has the last turn.
In case of Points Rummy, a fresh toss take place before every deal and so the dealer may change game to game. However, in Pool and Deals Rummy, the toss takes place once and the dealer moves to the next players in descending order as the game progresses. The dealer position changes from player to player with each hand. Top
