If you like a good treasure hunt, we have good news for you. Crystal Crop Fever is here! The game where you either play by yourself or as part of a team to find the most valuable hidden treasures. This is done with no initial clues of where to look, and if you work in a team you are not able to communicate during the game. You have to find your own way of locating the most valuable crystals! But what do we try to investigate with this game? We look at how people search and solve problems in unknown landscapes. Because how do you find the highest mountain when you can’t use your vision e.g. due to a thick fog? You would have to climb each mountain but which ones do you choose first? What kind of strategies are used to optimize the search? These are the things we are studying with Crystal Crop Fever. Play it in browser or on iPhone or Android and be part of our research.
