Gameplay elements and classification


Games can be characterized by "what the player does."[4] This is often referred to as gameplay, a term that arose among computer game designers in the 1980s but as of 2007 is starting to see use in reference to games of other forms.[citation needed] Major key elements identified in this context are tools and rules which define the overall context of game and which in turn produce skill, strategy, and chance.

Tools

Games are often classified by the components required to play them (e.g. miniatures, a ball, cards, a board and pieces or a computer). In places where the use of leather is well established, the ball has been a popular game piece throughout recorded history, resulting in a worldwide popularity of ball games such as rugby, basketball, football, cricket, tennis and volleyball. Other tools are more idiosyncratic to a certain region. Many countries in Europe, for instance, have unique standard decks of playing cards. Other games such as chess may be traced primarily through the development and evolution of its game pieces.

Many game tools are tokens, meant to represent other things. A token may be a pawn on a board, play money, or an intangible item such as a point scored.

Games such as hide-and-seek or tag do not utilise any obvious tool. Rather its interactivity is defined by the environment. Games with the same or similar rules may have different gameplay if the environment is altered. For example, hide-and-seek in a school building differs from the same game in a park; an auto race can be radically different depending on the track or street course, even with the same cars.

Rules

Whereas games are often characterized by their tools, they are often defined by their rules. While rules are subject to variations and changes, enough change in the rules usually results in a "new" game. For instance, baseball can be played with "real" baseballs or with wiffleballs. However, if the players decide to play with only three bases, they are arguably playing a different game.

Rules generally determine turn order, the rights and responsibilities of the players, and each player’s goals. Player rights may include when they may spend resources or move tokens. Common win conditions are being first to amass a certain quota of points or tokens (as in Settlers of Catan), having the greatest number of tokens at the end of the game (as in Monopoly), or some relationship of one’s game tokens to those of one’s opponent (as in chess's checkmate).

Skill, strategy, and chance

A game’s tools and rules will result in its requiring skill, strategy, chance or a combination thereof, and are classified accordingly.

Games of skill include games of physical skill, such as wrestling, tug of war, hopscotch, target shooting, and stake and games of mental skill such as checkers and chess. Games of strategy include checkers, chess, go, arimaa, and tic-tac-toe, and often require special equipment to play them. Games of chance include gambling games (blackjack, mah jong, roulette etc.), as well as snakes and ladders and rock, paper, scissors; most require equipment such as cards or dice. However, most games contain two or all three of these elements. For example, American football and baseball involve both physical skill and strategy while tiddlywinks, poker and Monopoly combine strategy and chance.

Single-player games

Most games require multiple players. However, single-player games are unique in respect to the type of challenges a player faces. Unlike a game with multiple players competing with or against each other to reach the game's goal, a one-player game is a battle solely against an element of the environment (an artificial opponent), against one's own skills, against time or against chance. Playing with a yo-yo or playing tennis against a wall is not generally recognised as playing a game due to the lack of any formidable opposition. This is not true, though, for a single-player computer game where the computer provides opposition.
