If you can take a photo, you can play MapGems. Take a photo with the MapGems app, then add information and clues to help others find your photo. A great photo is of something that you believe other users will enjoy finding and ID scanning.
Ideas for photos include: architecture, landmarks, sculptures, murals and public art. But more unique objects such as signs, manhole covers, markers and utility boxes may also be fun for others find.
A photo should be made of permanent objects in a public location which is easily and safely accessible (both feet on the ground) and appropriate for users of all ages. Photos should not be of people, animals, food, pets, etc.
