I would think all casinos would expect a dice toss outcome to be random, except with 7 appearing the most often, then 6/8, 5/9, 4/10/ 3/11, 2/12. The two craps tables were indeed crowded even at $10 and $15 minimums respectively. I suppose the players really believe that dice influencing can work with this new format. I just think it is only feasible influence the hard 4,6,8,10, though they carry 9-10% house edges.
From the same source of rumors, I heard the Pechanga is one of the rare casinos where slot attendants in the high limit rooms get higher income on tips than the carnival table games dealers.
