I'm sort of torn on this one because there have been some disquieting reports on Russian software, including Avogic. On the other hand, a respectable marketing agency, Ispye is doing their marketing and the casino manager Mike Jacobs seems to be very keen and responsive.
So I would suggest that you do a little research and draw your own conclusions. This is what we reported when these guys launched:
City of Kings.com has a pleasing, professional appearance and a responsive manager in Mike Jacobs, who tells us that this new operation is focused on good gaming (they have 15 games including most casino faves)
fast payouts and well-trained Support. The proof will be in player reactions a little further down the line, and we're not too sure about the ASTGaming Solutions provider which is the renamed Avogic suite. They're offering financial options with Neteller, eGold and 900Pay and a range of above average bonuses, particularly those aimed at high-rollers. The Support promise is a 15 minute turnaround on player emails, which is ambitious but do-able with the right staffing levels and expertise. Although based in Costa Rica, the owners appear to be King City Entertainment out of Collingwood, Ontario up there in the Great White North. We understand that the experienced ISpye consultancy is marketing the site.
