Funny Dan I had the same idea. My idea was that we start out in the biggest arcade and have different "rounds". Then after a couple of rounds we would move on to a different arcade. For example lets say 20 people start out the top 15 will move on to the next round. Also I was thinking everyone could put their tickets in a "pot" and the winner would get all the tickets.
