A game is a prepared or semi-structured activity, generally undertaken for enjoyment and sometimes also used as an learning tool. (The term "game" is also used to explain recreation of different activities e.g., for the purposes of training, study or prediction, etc,) Games are generally different from work, which is usually accepted out for payment, and from art, which is more concerned with the term of ideas. However, the distinction is not clear-cut, and a lot of games may also be considered work and/or art. Key components of games are goals, policy, challenge, and interactivity. Games generally involve mental or objective stimulation, and often both. Many games help develop useful skills, serve as a form of exercise, or else perform an educational, simulation or emotional role.
