could there be an option that when it is our turn that there can be a click the dice option, and it not be let up to the site itself??

Thank you for the suggestion. We'll consider it!

What is the formula for the rolling of the dices ? Is it based on the actual time of the roll ? I have the feeling that the rolling is not really random !

How can you tell if dice are "not really random"? If you get the same two dice in a row, it doesn't mean it's not random. If you get 3 doubles in a row, it still doesn't mean it's not random. It's just a matter of luck. Or lack thereof (pardon the pun  ).

Random, on a computer, does simply not exist !
Rolling of dices is based on a certain algorithm which is bases on a seed or the actual time or anything else which makes you believe it's random, but it's not.
I simply would like to know which algorithm is used.
And it's true that sometimes I feel very unlucky when my opponent makes double six two times in a row

It used to be that way, but now most Unix systems (including Linux and FreeBSD), provide a hardware based random number:
http://en.wikipedia.org/wiki//dev/random
It uses system/network interrupts and hard disk for true randomness. If it's good enough for use in generating cryptographic keys for high-value or long-term protection, it should be good enough for rolling dice in backgammon games. I'm assuming of course that this site is running Linux/FreeBSD, so please correct me if I'm wrong! Since it seems to be always available, it's probably not Windows.

We use hardware based /dev/random. See also this FAQ regarding dice.

Fair enough
