Well, I went searching for new slots last night at Red Rock Casino and I found some -- just not the ones I was hoping for.
I wanted to find the WMS' Money Burst and Rotating Wild machines, but instead stumbled upon some new versions of their G+ series. http://www.wms.com/games_videoreel.php
Par for the course these days -- there is no information on these slots on WMS' website -- but there they are bold as day on the casino floor.
The machines are "Egypt," "Roman Something Or Other," "Fortune Seeker," and "Samarai Something Or Other."
Okay, they aren't really called "Something Or Other," I just can't remember their names exactly, and frankly do we really need more Roman or Asian themes machines? Apparently, we do.
But, I digress . . . the G+ series are simple in their offerings, usually one bonus round, sometimes featuring stacked wilds, and volatile.
