We are in development of a social casino application (Slap-a-Slot)
Our Social Casino application is currently in a live test mode - https://apps.facebook.com/slapaslot/
We seek to build upon the success of previous social casinos (e.g. Slotomania, Mirrorball) with new features, some which have proven successful in non-casino apps but not yet exploited in our competition.
Our products are in live test, but are still undergoing modifications (e.g. addition of new features, changes to configuration as a result of AB testing, etc) for maximum usability and profitability, ahead of a proposed major launch later in the year.
