SCVNGR is a game all about going places, doing challenges and earning points. The game is played from a custom app on iPhone and Android as well as via SMS. It is not a text message scavenger hunt. Instead of riddles to guide you to a place, SCVNGR concentrates on completing challenges at a particular location.
