Gamification by Design sets out by defining three terms – gamification, engagement, and loyalty. Gamification is defined as “The process of game-thinking and game mechanics to engage users and solve problems”, a definition that “unite(s) concepts such as serious games, advergaming, and games-for-change into a cohesive worldview that’s informed by the latest research into behavioral psychology and the success of social games.” (p. xiv) (via A Quick Buck by Copy and Paste | Gamification Research Network)
