MODES OF PLAY

There are two modes of play: "table stakes" or "match play".

In TABLE STAKES, you and your opponent start with an equal number of chips. The goal is to collect all the chips before your opponent does. Use the doubling cube to increase the stakes. If you play with the "Jacoby rule", gammons and backgammon don't count unless the cube has been turned. If you play with the "Beavers rule", a player who accepts a double may immediately redouble and still keep the cube.

In MATCH PLAY, the goal is to be the first player to reach a specified total number of points. Use the doubling cube to increase the stakes. The "Crawford rule" takes the doubling cube out of play for one game when a player gets to within one point of winning.

You offer a double by sliding the cube over to your opponent's side of the board. Opponent can accept the double by pressing "Take" (the game continues at twice the previous stakes), or reject the double by pressing "Pass" (he loses the game and must pay the previous stakes.)

COMPUTER PLAYER

The computer AI is VERY strong. There are two levels of play: Average and Strong. Both are fun and challenging.
