Gamification involves using game mechanics and elements in non-game contexts to motivate and engage users. It works by appealing to human psychological tendencies. Companies are increasingly using gamification across industries to build loyalty and encourage customer engagement.

Current trends include social and status elements, virtual rewards, and blending gaming with media. Implementing gamification well can boost metrics like retention, revenues and time spent.
