Backgammon variant

Acey-Deucey · US Navy backgammon

Born on the mess decks of the US Navy and Marine Corps, Acey-Deucey is backgammon with the throttle open: nobody starts on the board, the 1-2 roll hands you any double you like plus another turn, and fortunes reverse twice a game. It crossed the world's oceans in seabags — and it is still the fleet's game.

How Acey-Deucey plays

  • Everyone starts at sea. All fifteen checkers per side begin off the board. You enter them into the opponent's home board exactly as if re-entering from the bar — a 1 enters on the opponent's 24-point, a 6 on their 19-point.
  • Entry is not imprisonment. Unlike bar re-entry in standard play, checkers still in your reserve don't freeze the rest of your army: once checkers are on the board you may move them even while others wait to enter. Only checkers actually hit to the bar take priority.
  • The acey-deucey roll. Rolling 1-2 is the game's jackpot: play the 1 and the 2, then choose any double (1-1 through 6-6) and play it, then roll again.
  • Extra rolls for doubles. In the American tradition Boardgammon follows, any double you play in full also earns another roll — hot dice stay hot.
  • Otherwise standard. Hitting, blocked points, and the standard bear-off law all apply.

Scoring

Traditional shipboard scoring has no cube; tables often score wins bigger by ending condition — double or more when the loser still has checkers waiting to enter, with conventions varying ship to ship. Agree before the first roll, exactly as with money-play options in the standard game.

Strategy in brief

  • Enter with purpose. Your entry rolls sketch your first structure — favor entries that build toward points rather than scattering blots.
  • Respect the swing. A 1-2 with a well-chosen double is worth roughly three turns; keep positions flexible enough to survive the opponent catching one.
  • Race awareness still pays. Behind the fireworks it is a race — count pips before committing to a hitting war.

A Mediterranean cousin — European Acey-Deucey — gives doubles different bonus treatment and thrives in cruise-ship card rooms and maritime communities.
