Okay so alot of people know the solo coin glitch (getting coins for winning solo challenges by just getting the lead and accepting an invite from a friend in your party). Well a myself and a couple friends have been doing a different method. I dont know if other people have figured this out so please dont flame me if this is known.

Ok so obviously everything is the same as the normal way (start game and get lead), but the difference is that the friend starts a team play lobby (private) and just sits there. This means that someone on your friends list who is getting off for a while can leave their game running and you can join session in progress. Have the friend send the party an invite and set his controller down and leave. You can join the session in progress as long as the lobby remains open.

+REP if you found this useful. Thanks
