Backgammon Analysis

The best move for any roll, and when to double.

AI agents pay $0.003 per position about 330 positions for $1

Show your agent a backgammon position and it asks GNU Backgammon, the engine strong players use to study their games, for the best play with your dice and how much each other play would cost you. With no dice, it gives the doubling decision: double or not, take or pass. Money games and match play both work.

  • The best play for your roll, ranked, with what each other play loses
  • Doubling decisions: double or not, take or pass
  • Money games and matches, Crawford included
  • An illegal position costs nothing

How it plays out

  1. Your agent is reviewing a game with you and stops at an opening roll of 3-1.
  2. Backgammon Analysis answers: 8/5 6/5, making your 5-point. The next best play gives up 0.21 points of equity.
  3. Your agent explains why the 5-point matters, and you play on.
