it could be the "greatest unintentional health fad ever," writing that one of the results of the game that the developers may not have imagined was that "it seems to be getting people moving." One study showed users took an extra 194 steps per day once they started using the app, approximately 26% more than usual. Ingress is a similar game that also requires a player to be physically active. Zombies, Run!, a game in which the player is trying to survive a zombie apocalypse through a series of missions, requires the player to (physically) run, collect items to help the town survive, and listen to various audio narrations to uncover mysteries. Mobile, context-sensitive serious games for sports and health have been called exergames. Work Gamification has been used in an attempt to improve employee productivity in healthcare, financial services, transportation, government, and others. In general, enterprise gamification refers to work situations where "game thinking and game-based tools are used in a strategic manner to integrate with existing business processes or information systems. And these techniques are used to help drive positive employee and organizational outcomes." Crowdsourcing Crowdsourcing has been gamified in games like Foldit, a game designed by the University of Washington, in which players compete to manipulate proteins into more efficient structures. A 2010 paper in science journal Nature credited Foldit's 57,000 players with providing useful results that matched or outperformed algorithmically computed solutions. The ESP Game is a game that is used to generate image metadata. Google Image Labeler is a version of the ESP Game that Google has licensed to generate its own image metadata. Research from the University of Bonn used gamification to increase wiki contributions by 62%. In the context of online crowdsourcing, gamification is also employed to improve the psychological and behavioral consequences of the solvers. According to numerous research, adding gamification components to a crowdsourcing platform can be considered as a design that shifts participants' focus from task completion to involvement motivated by intrinsic factors. Since the success of crowdsourcing competitions depends on a large number of participating solvers, the platforms for crowdsourcing provide motivating factors to increase participation by drawing on the concepts of the game. Education and training Gamification in the context of education and training is of particular interest because it offers a variety of benefits associated with learning outcomes and retention. Using video-game inspired elements like leaderboards and
