This is a metapuzzle, i.e., a puzzle that can only be solved after solving other puzzles. In this case, those puzzles are the puzzles for the August 2013 Puzzled Pint other than the location puzzle Variety; you can find those puzzles on this website. In Puzzled Pint, the puzzles are generally easy enough that teams will solve all of them, so the metapuzzle isn't necessarily designed to be solved with fewer than all the answers.
