As I heard many times, gamification is huge. It's somewhat a buzzword, I know, but gamification is very real, it works and these guys know that well. They say they make people do stuff through game mechanics. Even boring stuff sometimes — glorious!
Gameful is a studio tailoring game mechanics to your needs focusing on creating user engagement and amplifying customer interest in your product or service. They help you earn your customer's enthusiasm and loyalty.
So Gameful is a bit about people, a bit about game mechanics and a bit about branding, service design and overall UX design.
