Well i used only one dice, while i could use both, to test if the system will accept it. And suprisingly it did! Sorry about that.

Anyway, as i'm very pedantic with game rules:
IT IS A BIG DEAL THIS BUG. In the game of Backgammon you have to use the maximum number of your rolled numbers to have a legal move. So this game here, cannot be called Backgammon. Of course with the agreement you said, that the players must play it, although they have the option to do the opposite, the game can be called Backgammon again. So all the players must know about it! Perhaps you should write it to the game rules of Backgammon. Sorry if i seem too pedantic but i always want to be 100% accurate.
