I just received from BROOKSTONE / EXCALIBUR ELECTRONICS, a hand held "Touch Screen Backgammon". It was advertised as "an increasingly challenging" game. An imbecile could not find this game challenging. It has a book of rules to play which it ignores as it does all the standard rules know to experienced players. This is one of the worst scams I have seen. It is not worth the cheap price to bother to do anything with it.
