What is a game? A games is a structured activity that is usually for entertainment and sometimes used as an educational tool. Games are distinct from work, which is usually carried out for remuneration, and from art, which is more concerned with the expression of ideas. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports/games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong or solitaire). Games that are being played over the Internet are referred to as online games. MMOs and MMORPGs are popular online games that involve a huge number of players. Many of them utilize 3D technology considered as 3D games. Key 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, serve as a form of exercise, or otherwise perform an educational, simulation or psychological role. According to Chris Crawford, the requirement for player interaction puts activities such as jigsaw puzzles and solitaire "games" into the category of puzzles rather than games. They can be divided into Core, Serious, or social games. Furthermore, there are also Social, Sports, Tabletop and Video Games such as a standalone PC games or online games. Is Club Cooee a game?
