Backgammon 3D is a 3D visualization of a classical board game - Backgammon. Now you can play with your computer not only on a flat screen, but also enjoy 3D operations - rotating the board, looking at the board from the side of your opponent, and other cool features.
The first strong backgammon computer opponent was BKG 9.8. It was programmed by Hans Berliner in the late 1970s on a PDP-10 as an experiment in evaluating board positions.
