If this was connected to prizes/tournaments, from what I remember it depends
on whether the user pays to play or not; and the laws of the country that
your site is hosted in.

>From a UK perspective, if the user paid to play you'd need a gaming and/or
gambling license (gaming for fixed-odds, gambling for games of skill - I
assume Backgammon would come under the latter).

I know that to get one of those licenses in the UK (for interactive TV
gaming, which is why I'm being a bit woolly about the website thing) we
needed to buy a much better random number generator. In fact - a hardware
random number generator, with certification that we could show the
authorities.

This Wikipedia entry explains about hardware generators:
http://en.wikipedia.org/wiki/Hardware_random_number_generator

If your game isn't pay-to-play, I _think_ you'd be in the clear and could
use whatever randomness your client was happy with; as essentially your
client would be giving away stuff for free. If it is pay to play, you need
to check it all out with the lawyers, I'm afraid.

Hope that's helpful,
Ian
