I tried something different today and got two games in a row instantly. I normally have my setting as "offline". Today when I changed that to online a game came up immediately. I will need to try it a couple more times to see if that is what made the difference or if it was coincidence, but worked twice in a row today.
Btw... That's was for Alt Shot
EDIT: It must have been coincidence. I am unable to find a game again this morning.
