At the time of written this guide i noticed most of the peoples on lobbies are avoiding playing with random players they set max players to 2 or they lock the ring match with a password and i can understand why because there are some crazy pro players out there they will destroy you without even being able to move or do anything so your best bet is to get a friend or 2 and lock the ring with a password.
Once you are on lobby area you can start the match by LT and choose the setting that suits you.
Trust me you wont like playing with any of the random peoples there you will be dominated like what happens to me lol.
Anyway just enjoy playing with your friends and good luck.
