Welcome to the Mathmagical land of Kansas City! You know of its fountains, its barbecue, its night-life, and more, but now you're about to embark on a Mathmagical tour of Math puzzles that will also take you to some interesting locations in the city.
This is not meant to be a single quick grab. It involves solving seven puzzles (including the one on this page) and visiting seven locations around the city, each one involving finding and scanning a QR code. The stages are set up to be done in order, but it's not necessary to do all of them at once. In the end, you'll be taken to an interesting location where you'll find the final geocache.
You will need a QR code reader to complete this geocache.
