Match Making Help!

I’m making a Battle Royale game but I have no idea where to start on the match making.
I have the server part done but the match making part is tricky.

hmm here’s a diagram i made…
This is just a way of thinking about it:


@Fus_ion would you be willing willing to help me make a system like this? You would be credited.

Sure but no credit would be fine, i just help people on my spare time

ok thank you.
