High Roller Roxy
Roxy has many of the benefits, and some of the drawbacks of the others.
I have found that there IS an eventual ceiling to all the 30% bonuses, I went smack right into it in early May. This only affects the newsletter bonuses, tournament prizes and GoneGambling wins are still OK. Roxy are one of the few that allow GG Point conversions, as well as a GoneGambling high roller bonus, and have their very own GoneGambling game where members can play for extra bonuses.
One drawback is the 48 hour pending time on withdrawals, many casinos now have 24 hours, and will also flush on request, something Roxy Palace does not offer.
One positive difference is their contribution to responsible gambling, they use much lower coin limits on many of the games than the MG Standard, although a few games seem to have slipped through the net.
They have rectified one issue that arose recently, and it is possible to specify how you want to receive your withdrawal from the banking page. The default is a Cheque after deposits are refunded to their point of origin.
As far as I am concerned, they are just another good MG casino, offering some benefits over the competition, as well as lagging the competition in some respects.
I have not heard of a case where Roxy Palace confiscated winnings, although they must surely be victim of "fraud" just as much as the rest.
