Games are being used to drive engagement in many aspects of life from health to education to social issues. Well-designed games provide meaningful goals, feedback, progression and social elements that create compelling long-term engagement. Examples discussed include health apps like Run Keeper that gamify exercise, classroom blogs that awarded badges to drive student participation, and social games like World Without Oil that sparked dialogue around resource crises by simulating scenarios. Gamification techniques are transforming industries and institutions by motivating behavior change and innovation through game mechanics.
