The following outline is provided as an overview of and topical guide to games and gaming:

Games are structured or semi-structured activities usually undertaken for enjoyment. They are usually fun activities that can be educational or purely just for fun. The term "game" is also used to describe simulation of various activities e.g., for the purposes of training, analysis or prediction, etc., see "Game (simulation)". Games are a universal part of the human experience, for all cultures, genders and ages. Key components of games are goals, rules, challenge, and interactivity. Games generally involve mental or physical stimulation, and sometimes both. Many games help develop practical skills, serve as a form of exercise, or otherwise perform an educational, simulational or psychological role.

Individuals participate in game-play for various reasons, depending upon the aspect the particular game covers. These include:

  • Hobby
• Strategy

• Game board (or simply board) – the (usually quadrilateral) surface on which one plays a board game; the namesake of the board game, gameboards would seem to be a necessary and sufficient condition of the genre, though card games that do not use a standard deck of cards (as well as games which use neither cards nor a game board) are often colloquially included. Most games use a standardized and unchanging board (chess, Go, and backgammon all have such a board), but many games use a modular board whose component tiles or cards can assume varying layouts from one session to another, or even as the game is played.
