I am trying to create an ansynchronous turn-based game that basically works like chess or words with friends where a player can start a game against a random opponent but can take their turn at any time as long as the turn is made in a time limit of 1 week for example. When a player attempts to find a random match they will either make the 1st move and then wait for another player to get matched to that game or get matched into a game where the 1st move is already made and then make the 2nd move. The actual matchmaking should be based on skill level or other criteria.

I want to matchmaking to work similar to the Heartstone example but the actual mechanics of the matching to work like the turn based challenge tutorial. In the heartstone example it feels as though the expectation is that both players are online during the matchmaking and for the turn based challenge tutorial, I am not sure how to make that work with random skill based matching.

Is this possible and any advice on how to do this?

I wanted to follow up and confirm if matchmaking will work for my use case. Does matchmaking require both players to be online? Also, does matchmaking require a threshold to be set with a maximum value of 3600 seconds?

Finally, if matchmaking wont for random asynchronous matches because of these limitations, is the only alternative to use FindChallengeRequest and implement my own matchmaking based on the list of challenges returned?

Even, if FindChallengeRequest would work, I want to find a way to implement the different matchmaking thresholds that I would have when using MatchmakingRequest without falling back on somehow scheduling another script to run if a challenge isnt found.
