"I've been following Yu-kai's work on gamification for years and have enjoyed his deep insights and actionable recommendations. Octalysis is a powerful and pragmatic framework to understand human nature and positive motivators that encourage people to do their best work. It's great that Yu-kai was able to capture his thoughts into this framework and can share it with others through this book.

Yu-kai's reputation precedes him in the field of gamification. His Octalysis framework is both elegantly simple and intricately complex. His book is not only extrinsically rewarding to read, but intrinsically motivating to apply; it's wickedly effective, and yet divinely true. Octalysis brilliantly unified all these seemingly conflicting aspects of gamification into a single cohesive framework with a hidden twist in the middle of it it s sensational. --Michael Wu, Chief Scientist of Lithium
