Paper and pencil game

Paper-and-pencil games or paper-and-pen games (or some variation on those terms) are games that can be played solely with paper and pencils (or other writing implements), usually without erasing. Examples of paper-and-pencil games are Tic-tac-toe, Sprouts, and Dots and Boxes. Other examples include: Hangman, Connect 5, M.A.S.H., Battleships, Paper Soccer, and WedgoLogic.

Additionally, the term is used to distinguish role-playing games of the tabletop variety from role-playing video games, although those traditional role-playing games do not necessarily use either paper or pencils.

In some board games, particularly abstract strategy games like Gomoku, a piece, once played, will not be moved or removed from the board. Such games can be played either as board games or as paper-and-pencil games, while many other paper-and-pencil games require the use of writing utensils.

Board game

Board games are traditionally a subset of tabletop games that involve counters or pieces moved or placed on a pre-marked surface or "board", according to a set of rules. In common parlance, however, a board game need not necessarily contain a physical board. Some games are based on pure strategy, but many contain an element of chance; and some are purely chance, with no element of skill.

Games usually have a goal that a player aims to achieve. Early board games represented a battle between two armies, and most modern board games are still based on defeating opponents in terms of counters, winning position, or accrual of points.

There are many varieties of board games. Their representation of real-life situations can range from having no inherent theme, such as checkers, to having a specific theme and narrative, such as Cluedo. Rules can range from the very simple, such as in Snakes and Ladders; to deeply complex, as in Advanced Squad Leader.

The time required to learn to play or master a game varies greatly from game to game, but is not necessarily correlated with the number or complexity of rules; games like chess or Go possess relatively simple rulesets, but have great strategic depth.

Video game

A video game is an electronic game that involves interaction with a user interface to generate visual feedback on a two- or three-dimensional video display device such as a touchscreen, virtual reality headset or monitor/TV set. Since the 1980s, video games have become an increasingly important part of the entertainment industry, and whether they are also a form of art is a matter of dispute.

The electronic systems used to play video games are called platforms. Video games are developed and released for one or several platforms and may not be available on others. Specialized platforms such as arcade games, which present the game in a large, typically coin-operated chassis, were common in the 1980s in video arcades, but declined in popularity as other, more affordable platforms became available. These include dedicated devices such as video game consoles, as well as general-purpose computers like a laptop, desktop or handheld computing devices.

The input device used for games, the game controller, varies across platforms. Common controllers include gamepads, joysticks, mouse devices, keyboards, the touchscreens of mobile devices, or even a person's body, using a Kinect sensor. Players view the game on a display device such as a television or computer monitor or sometimes on virtual reality head-mounted display goggles. There are often game sound effects, music and voice actor lines which come from loudspeakers or headphones. Some games in the 2000s include haptic, vibration-creating effects, force feedback peripherals and virtual reality headsets.

A game is a structured form of play, usually undertaken for enjoyment 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 often an expression of aesthetic or ideological elements. However, the distinction is not clear-cut, and many games are also considered to be work (such as professional players of spectator sports or games) or art (such as jigsaw puzzles or games involving an artistic layout such as Mahjong, solitaire, or some video games).

Games are sometimes played purely for entertainment, 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.

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, simulational, or psychological role.
