As much as I enjoy the support at 3Dice, I often wonder about this "high variance" theory. If you look at the winner screen shots, there are many "high variance" slot wins with MG and others. They seem to happen at least as often for me as they do at 3D, without the more frequent low to nil wins inbetween. I am not sure how 3D really differs from what's out there with the exception of longer dry spells and poor paybacks most of the time (unless you are a newer player- wins are most definitely cyclical from my experience!)
Certainly when I have on occasion hit free spins at 3D I have had my share of poor pay backs such as 10X bets, even after very long dry spells.
I hit this last week at MG- 833+ X win. I hit the same thing at another MG with a $1.80 bet. Should MG slots be called HV as well?? I would like to understand how you differentiate yourself from what's out there already, aside from your great and responsive support staff.

I think others could post screenshots that suck upon finally hitting bonus rounds at 3D. Just trying to keep you honest Enzo!
