A method of locating a target in a geographical space includes providing information to searcher users searching for the target, and potentially selecting among multiple targets for location, and providing rewards to the searchers after locating the target. The target may be a virtual object, and the method may use augmented reality features in locating the virtual object. The method may also provide for participating users who are not actively searching for the target, but may team with a searcher to receive a reward if the searcher locates the target, and who may potentially assist the user in locating the target. Participating users may be eligible if they are located in a designated participation area. The method may further provide for observing users who can observe progress of searchers in searching for the target but are not involved in the search or reward.
