I suggested something like this at some time... somewhere.

Basicly my thoughts are you can see your opponents dice, and that is about it.

Basicly played just like regular backgammon, with this additional rule:

If you move one (or more) of your pieces to a space which has 2 or more of your opponenets pieces, YOUR pieces get sent back to the bar. (Since you can't see your opponents pieces, this is a possibility)

I think it would be fun with regular backgammon, but I think it would be even more fun as Dark Backgammon Race.
