This presentation looks at how gamification taps into how our brains work. It focus on the role of reward schedules and uncertainty in creating engagement. It also briefly discusses whether or not the term 'gamification' itself is a fad or not.
NOTE: Apologies for the low image quality of the slides. The only way I was able to upload the deck without producing visual artifacts during the SlideShare conversion process was to upload each slide as an image :(
