Munzee is a freemium scavenger hunt game where places have to be found in the real world. The game is similar to Geocaching but uses QR code technology, in addition to device GPS location, to prove the find instead of a logbook. Launched in Texas in 2011, the game caught on first in Germany, along with California and Michigan. It is now played in more than 188 countries around the world, and there is at least one physical Munzee deployed on every continent, including Antarctica.
