). Games are sometimes played purely for enjoyment, sometimes for achievement or reward as well. They can be played alone, in teams, or online; by amateurs or by professionals. The players may have an audience of non-players, such as when people are entertained by watching a chess championship. On the other hand, players in a game may constitute their own audience as they take their turn to play. Often, part of the entertainment for children playing a game is deciding who is part of their audience and who is a player. A toy and a game are not the same. Toys generally allow for unrestricted play whereas games come with present rules. Key components of games are goals,

Roger Caillois

French sociologist Roger Caillois, in his book ''Les jeux et les hommes (Games and Men)''(1961), defined a game as an activity that must have the following characteristics: * ''fun'': the activity is chosen for its light-hearted character * ''separate'': it is circumscribed in time and place * ''uncertain'': the outcome of the activity is unforeseeable * ''non-productive'': participation does not accomplish anything useful * ''governed by rules'': the activity has rules that are different from everyday life * ''fictitious'': it is accompanied by the awareness of a different reality

Game designer Chris Crawford defined the term in the context of computers. Using a series of

Crawford's definition may thus be rendered as: an interactive, goal-oriented activity made for money, with active agents to play against, in which players (including active agents) can interfere with each other. Other definitions, however, as well as history, show that entertainment and games are not necessarily undertaken for monetary gain.

Gameplay elements and classification

Games can be characterized by "what the player does". This is often referred to as

Rules and aims

Games are often characterized by their tools and rules. While rules are subject to variations and changes, enough change in the rules usually results in a "new" game. For instance,
baseball Baseball is a bat-and-ball sport played between two teams of nine players each, taking turns batting and fielding. The game occurs over the course of several plays, with each play generally beginning when a player on the fielding tea ...

s. However, if the players decide to play with only three bases, they are arguably playing a different game. There are exceptions to this in that some games deliberately involve the changing of their own rules, but even then there are often immutable meta-rules. Rules generally determine the time-keeping system, the rights and responsibilities of the players, scoring techniques, preset boundaries, and each player's goals. The rules of a game may be distinguished from its aims. For most competitive games, the ''ultimate'' aim is winning: in this sense, checkmate is the aim of chess. Common win conditions are being first to amass a certain quota of points or tokens (as in
Settlers of Catan ''Catan'', previously known as ''The Settlers of Catan'' or simply ''Settlers'', is a multiplayer board game designed by Klaus Teuber. It was first published in 1995 in Germany by Franckh-Kosmos Verlag (Kosmos) as ''Die Siedler von Catan''. Pl ...

). There may also be ''intermediate'' aims, which are tasks that move a player toward winning. For instance, an intermediate aim in football is to score goals, because scoring goals will increase one's likelihood of winning the game, but isn't alone sufficient to win the game. An aim identifies a

that a player must score a goal on a penalty; while it is expected the player will try, it is not required. While meeting the aims often requires a certain degree of skill and (in some cases) luck, following the rules of a game merely requires knowledge of the rules and some careful attempt to follow them; it rarely (if ever) requires luck or demanding skills.

Single-player games

Most games require multiple players. However, single-player games are unique in respect to the type of challenges a player faces.

Many sports require special equipment and dedicated playing fields, leading to the involvement of a community much larger than the group of players. A city or town may set aside such resources for the organization of sports leagues. Popular sports may have spectators who are entertained just by watching games. A community will often align itself with a local sports team that supposedly represents it (even if the team or most of its players only recently moved in); they often align themselves against their opponents or have traditional rivalries. The concept of

Tabletop games

A tabletop game is a game where the elements of play are confined to a small area and require little physical exertion, usually simply placing, picking up and moving game pieces. Most of these games are played at a table around which the players are seated and on which the game's elements are located. However, many games falling into this category, particularly

or cards. Most games that simulate war are board games (though a large number of video games have been created to simulate strategic combat), and the board may be a map on which the players' tokens move. Virtually all board games involve "turn-based" play; one player contemplates and then makes a move, then the next player does the same, and a player can only act on their turn. This is opposed to "real-time" play as is found in some card games, most sports and most video games. Some games, such as

Domino and tile games

Domino games are similar in many respects to card games, but the generic device is instead a set of tiles called

, which traditionally each have two ends, each with a given number of dots, or "pips", and each combination of two possible end values as it appears on a tile is unique in the set. The games played with dominoes largely center around playing a domino from the player's "hand" onto the matching end of another domino, and the overall object could be to always be able to make a play, to make all open endpoints sum to a given number or multiple, or simply to play all dominoes from one's hand onto the board. Sets vary in the number of possible dots on one end, and thus of the number of combinations and pieces; the most common set historically is ''double-six'', though in more recent times "extended" sets such as ''double-nine'' have been introduced to increase the number of dominoes available, which allows larger hands and more players in a game.

Additionally, the playing of a video game does not require the same physical skill, strength or danger as a real-world representation of the game, and can provide either very realistic, exaggerated or impossible physics, allowing for elements of a fantastical nature, games involving physical violence, or simulations of sports.

In more open-ended computer simulations, also known as sandbox-style games, the game provides a virtual environment in which the player may be free to do whatever they like within the confines of this universe. Sometimes, there is a lack of goals or opposition, which has stirred some debate on whether these should be considered "games" or "toys". (Crawford specifically mentions Will Wright's ''

Role-playing games

Role-playing games, often abbreviated as RPGs, are a type of game in which the participants (usually) assume the roles of characters acting in a fictional setting. The original role playing games – or at least those explicitly marketed as such – are played with a handful of participants, usually face-to-face, and keep track of the developing fiction with pen and paper. Together, the players may collaborate on a story involving those characters; create, develop, and "explore" the setting; or vicariously experience an adventure outside the bounds of everyday life. Pen-and-paper role-playing games include, for example, ''

Business games

Business games can take a variety of forms, from interactive board games to interactive games involving different props (balls, ropes, hoops, etc.) and different kinds of activities. The purpose of these games is to link to some aspect of organizational performance and to generate discussions about business improvement. Many business games focus on organizational behaviors. Some of these are computer simulations while others are simple designs for play and debriefing. Team building is a common focus of such activities.
