Don't worry, we already developed a Coin2 back-end (PHP) which will work with any games.
Have you any docs? Is it a web service or PHP classes for whichever server needs them?
Apologize for the lack of knowledge but does this include app based games u can download from say a google play store?
Other than apple/ googles policies, there is probably no reason why a game app couldn't have C2 rewards that could be "cashed in" when the user went online but the app writer would have to include the appropriate code within the app. The problem then would be how you authenticate to the VPS server and "prove" that the pay out request is genuine rather than some hacker looking for free C2. I suppose you could also build into the server some rules that allow you to restrict the number and size of payouts to each specific C2 address by a registered game in say a 24hr period limiting the potential damage if a hacker did manage to get access. But I'm sure Nelson has this all sorted. Like yourself I was just trying to get an idea of how it worked and therefore what it might be capable off.
