A game is a set of activities involving one or more players. It has goals, constraints, payoffs, and consequences. A game is rule-guided and artificial in some respects. (Richard Wilson, 2010). According to Garris et al. (2002), define educational game play as “voluntary, nonproductive, and separate from the real world”; and they found that the fantasy, goals, sensory stimuli, challenge, mystery, and control are the six features that characterize games. Generally, a game an activity must include several basic characteristics. The activity is usually a contest of physical or mental skills and strengths, requiring the participant(s) to follow a specific set of rules in order to attain a goal. Gaming is defined as being separate from simulation and is defined, in a basic sense, as any overt instructional or learning format that involves competition and is rule-guided (Dempsey et al, 1994)
