Professor Tofty said: "the contest winners aren't chosen based on the votes, they're chosen at random."

Assuming you mean the Predict the Madness winners, as in the people who create brackets, you have to either have a 100% correct bracket or, in the absence of any 100% correct brackets, a mostly correct bracket in order to be eligible to win one of the prizes described above. When you create a bracket, you are guessing which character you think will win each round.
