Should the Geojam app have scavenger hunt capabilities that provide rewards?

I imagine artists or festivals/venues providing scavenger hunts with QR codes that provide hints at where the next QR code would be. Each QR code would have promos and/or tasks that each user would need to perform. Like following a Twitter account or using a hashtag for an Instagram post, visiting a vendors booth, so on and so fourth. This could be a great feature to get engagement for an artist that creates a pool of rewards for participants.
