It has been a very long and interesting day. I have worked through the night and well in to today working on the Leaderboard system for my CashOnTap Mobile game. https://cashontapgame.com for those that are interested.
Right now I only have the Android build in the release cycle, but the iOS version is well into the testing stage.
You can expect a write up once I have it all figured out and working, this knowledge of how to make it work will be interesting to many game developers I am sure.
