Hi,
Thanks for your question.
Everest Gaming is a software company that is behind proprietary software for Everest Casino, Casino Elegance, Imperial Casino and 5 other brands. 150+ games are developed by Everest Gaming (previously named as Grand Virtual software).
Starting from April 2012 Everest brands also use some third party games, so you can find some other games in our clients (Casper, Superman, etc) from a handful of different software companies.
Please get back to me if I can help you further
Thanks
Dimitri
