Games

A game is structured playing mostly for fun and sometimes used as an educational tool. Games are different from the job, which normally provided for remuneration, and from art, which is more often an expression of aesthetic or ideological elements.
However, the difference is not clear, and many games considered to be work (such as professional players of spectator sports / games) or art (such as jigsaw puzzles or games with an artistic layout as Mahjong, solitaire, or some video games).

The main components of games are goals, rules, challenge, and interaction. Games generally involve mental or physical stimulation, and often both. Many games help develop practical skills, is a form of exercise, or otherwise perform an educational, simulational or psychological.
