We assimilated gamification and advertising by creating a Spot-the -Difference game that uses mobile adverts instead of stock images. Users get cash incentives and can buy deals offered by merchants with their earned credits.
We launched 4 weeks ago and have 2900 users who spent more then 6.5 million seconds simply looking at adverts.
Merchants buy credits on our portal from which we take a cut and the remaining can be allocated to their adverts.
