This sounds like normal variance. How much did you wager at Casino US before deciding that their payout is low? Do you believe that Microgaming operators have the ability to adjust their casino's payout, so payouts may be consistently less at one Microgaming casino than other? Do you believe that the Casino US audit reports that show payouts in line with other Microgaming casinos have been falsified?
It would also be normal variance to be ahead with 6 consecutive deposits but that has never happened.
Below 55% (not 50% as I said) is very low and possibly I was just very unlucky but yes I do believe individual operators can set their own payouts with MG software.
Have not checked their Audit but I would take any Casinos figures that is not properly regulated with a huge pinch of salt.
If I was saying they had been falsified I would need very good evidence first.
I probably played a few 1000 spins so not a massive sample although the features were very scarce and always payed poorly.
Also I forgot to mention that my comp points were still at Zero even though I played over several Days.
CS said it might be a little slow updating, I said I had made sveral deposits and played over the course of a Week, very slow indeed.
All they could say was to keep checking despite there being an obvious problem..
So their CS was also poor so I am just advising folk about my experience there, I am not saying they are rogue.
Play there by all means but IMO there are much better choices.
