Coin Hunt World (CHW) is a free-to-play/play-to-earn mobile Geo-location game currently in Beta on iOS and fully released on Android. Players explore their real-world area searching for Blue Keys, which are then used to open Blue Vaults. When a vault is opened the user is prompted with a trivia question. If answered correctly within the given time limit, the user is rewarded. Currently users are rewarded in Bitcoin or Ethereum as well as in game items such as Cubies, and Resources.
