You could make it either a very short tournament where just a few move on until you get a winner and then start an entirely new contest or, and this means more work for you, keep a running tally of correct answers and when you have done all the pics see who got the most right.This is based on a tournament with multiple rounds to go. Do we really only want a few people to move on? I guess we can go back to the "Just for fun" method.
