Create a treasure hunt app

We want to create an "App" but it will probably actually need to be an HTML5/Hybrid app as we want it to be usable on all devices Features: • Access via QR Code and/or via our web page • Users must enter Name & Email Address in order to sign up (to build database) • The App is essentially a treasure hunt / quiz where points are scored for locating clues or answering questions • Single Base Questions (excluding multi choice / true or false) • Points are accumulated throughout the progression through the app, so at the end of the game an individual score is achieved and a “highest scores” leader board can be viewed It will not be possible for players to go back and edit or correct previous answers • High Scores Leader Board • Rewards and Achievements can be earned and redeemed • the app should help to build Social Media presence • Encourage Users to upload photos from their tour to Facebook •Ability to show advertising • Log number of times a QR code is scanned • In app purchases possible • Want to be able to extend the game by buying extra levels
