Beating Intellivision at backgammon is a lot of fun. But it's definitely not child's play.

The computer knows all the tricks -- and it calculates all the odds before it moves.

Can you find a flaw in its strategy? Can you give it pieces to gobble up freely, then trap it in the back game? Or will you just cross your fingers, press the button and roll the dice?

Perfect your own backgammon skills with this modem version of one of the world's oldest games.
