I have a small game I have written in Unity (at present only for Android). It is a very simple game where you get more points the longer you last. Nothing complicated.
In order to help "spread the word," I want to enable players to challenge others to see who can score higher. I am not talking about their all-time high scores (these I save in the Google Game Play leaderboards).
How can I easily manage a one-to-one challenge?
I can't seem to find a straight forward way to do it using the Google SDK. It has the turn based play option but in my case each one plays separately. When both have played, the results get compared.
Short of setting up my own backend, how can I go about this?
Note: I am happy to use the FB SDK if necessary since that is how the challenges will be generally sent.
