Are u tired of playing conventional Treasure hunt game.Then try my app which works in augmented reality.In which the user has to sign in and after a particular time the game begins in which he has to give the correct answers.when his/her is write then the page redirects to map where the hint for the next question is displaed in the map.after going there he has to scan the qr code and it goes to next question and so on so..
-ZXING library(for qr code)-google maps api -Firebase Authentication
-Firebase Realtime Database
