Mineral hunter is a GPS Location Base game where you have to search for minerals in your real environment. With your Smartphone you can locate them in the physical world. You have to go outside to find them, a nice sporting challenge but also a healthy activity. Currently you can find six different Minerals with each their unique value (Points). The more you find the higher you will be in the ranking !!
Mineral Hunter is a one-man project that is being worked in my own leisure time.
