A game is a structured type of activity, normally undertaken for fun or entertainment, and at times used as a teaching tool. Games are quite different from work, which frequently are carried out for monetary remuneration, and in comparison to art, which more often is an expression of artistic or aesthetic elements. Work is structured; it has definite beginnings and endings, a defined beginning and end, definite goals and a defined method of achieving those goals. With games, the whole picture is open, and the aim is to achieve the purpose of the game without any unnecessary complications (if, that is, there is any such complication). Game design has become an important part of the study of computer science, and the increasing number of popular games is attributable in large part to this.
Games that involve complex planning and logical thinking, such as chess and checkers, require players to apply their knowledge in a very realistic way. Much like football, basketball, baseball, cricket and other sports, the rules of the game can be adapted and changed to the changing needs of the players. In games like these, the rules can be manipulated to suit the interests of the participants in the game. Chess is a classic example of this; there are several different chess variations, each of them requiring the player to apply their own unique set of strategies to beat their opponent.
There are many other types of games, including video games, word games, puzzles and musical games. Some video games require that the player to engage in a particular form of activity, such as driving a race car or participating in a space mission. Other games are more interactive, requiring players to interact with the game’s world and its characters. The variety of games available is amazing, and virtually every hobby and recreational activity can be made into a video game.
