When you see Oz out in the world, take a picture and upload it.
Sometimes unique one of a kind spottings happen. It maybe a tattoo or an old sign somewhere out in the bush. The gamemaker will judge uniquness upon upload and assign points.
Be the first to spot Oz at a specific location and get extra points. Location information must be sent with the upload.
If you spot Oz at a location after someone else has, no worries, you still get points. Location information must be sent with upload.
Even if you don't like to share location information with the game, you're still an important part of the game.
