Yea, most of the turn-based games sites (like here, IYT, and I think Gold Token) do not go by the rules when it comes to that - unless the site is made just for Backgammon ( DailyGammon) - it seems like some of the "odd" rules are left out.
I have also found this problem:
--------------
Lets take for example if you roll a 6 and a 2. Lets say only 1 of your checkers are able to move 6 spaces (and many can move 2 spaces)
So instead of moving that 1 checker 6 spaces, you move it only 2 - leaving the "6 dice" to do nothing, and your move is ended.
-------------------------
It's a known problem here - but also on the other games sites as well.
Question is: Do we want to waste the site administrators time fixing these small problems, or getting new games up and running? (I vote for new games)
