At Marco's cup game in Rockland, there is a pattern to the placement of the coin.

Right, Center, Center, Left, Right, Left, Right, Right, Left, Center, Left, Center, Right, Right, Right

If you bet 10,000 bits every time you'll end up with 150,000 bits! Keep in mind though that the
pattern resets every time you leave and that once you recruit Marco you won't be able to do this
trick ever again, so stock up on money early!
