Acey-deucey is a variant of backgammon, which features a differing starting position, opening play, and rules for the endgame and the use of the doubling cube. Because checkers may be retained in one's opponent's home board, the game offers substantial opportunities for backgame play.

Backgammon is a board game for two players in which pieces are moved according to the roll of dice. The winner is the first to remove all of one's own pieces from the board. Many variants have developed throughout the world, but most share common elements. It is a member of the tables family, one of the oldest classes of board games in the world.

Although the game has a substantial random component, backgammon offers a significant scope for strategy. With each roll of the dice, a player must choose from numerous options for moving the checkers and plan for possible counter-moves by the opponent. Opportunities for raising the stakes of the game introduce more strategic intricacies. Players have developed a vocabulary for common tactics and occurrences.

Like chess, backgammon has been studied considerably by computer scientists. Research has resulted in backgammon software that is capable of beating world-class human players.
