Can you discuss more about Mentava's approach to gamification? I am working on a math practice application and considering adding some, but I don't want it to be annoying.

Of course! Gamification (and other extrinsic motivators) are best used sparingly and short-term in order to get over an initial hump before something fun or easy. Think of climbing a hill to get to a playground.

Basically, our goal is to make the kid's progress tangible and visual for them so that they can start enjoying it, and then use our gamification mechanics to reinforce the child's growing intrinsic motivation so that they enjoy and appreciate the feeling of making progress
