1dk9f

1dk9f Game is a structured activity, usually undertaken for enjoyment and sometimes used as an educational tool. 1dk9f 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 1dk9f games are also considered to be work (such as professional players of spectator sports/1dk9f games) or art (such as jigsaw puzzles or 1dk9f games involving an artistic layout such as Mahjong solitaire).

Key components of 1dk9f games are goals, rules, challenge, and interaction. 1dk9f Games generally involve mental or physical stimulation, and often both. Many 1dk9f games help develop practical skills, serve as a form of exercise, or otherwise perform an educational, simulational or psychological role. According to Chris Crawford, the requirement for player interaction puts activities such as jigsaw puzzles and solitaire "1dk9f games" into the category of puzzles rather than 1dk9f games.
