I think the dice are random. The average game has a total of 75-100 rolls if played to the finish without resigning. That being said, 2 - 3 sets of ALL doubles would be observed in any given game. Do they occur more frequently from time to time; of course. It would take at least 100,000 rolls to obtain an unbiased trend analysis which none of us wish to take time to do. However, if extra 66, 55 etc are interjected into the dice, I don't think the server knows which player will get them. If this is the case, then it's still fair but not necessarily random. Does that make sense my friend? Good Rolling, Dave
