Acey-deucey is a variant of backgammon. Since World War I, it has been a favorite game of the United States Navy, Marine Corps, and Merchant Marine. Some evidence shows that it was played in the early 1900s aboard U.S. Navy ships. The game is believed to be rooted in the Middle East, Greece, or Turkey, where there were variants in which the game started with pieces off the board.
Compared to standard backgammon, acey-deucey is more like a race than a strategy game. It features a differing starting position, opening play, and rules for the endgame. Because pieces may be retained in one's opponent's home board, the game offers substantial opportunities for backgame play.
