People not playing a game that are trying to influence gameplay of a game by influencing the actions and opinions of the players.
In many cases when games are being played, people not playing the game are able to observe it. Those people that also try to affect the outcome of the game through communicating with the actual players are Backseat Gamers.
Note: Although players rather than gamers are used in this pattern to describe those engaged in gameplay, those trying to affect the gameplay are described as gamers. This since the influence they are trying to achieve typically relates to manipulating the game state, i.e. gaming, rather than the other types of activities a game can support.
Cheering crowds in Sports such as Soccer or Ice Hockey are Backseat Gamers. So are the coaches of sport teams although they typically have more explicit abilities (and power) to control the players actions.
Single-player Computer Games are typically games that easily accommodate Backseat Gamers since several people can simultaneously view the display showing the game. While fast-paced games can make giving advice hard, game focusing on open world exploration (e.g. the Elder Scrolls series and Minecraft) or Turn-Based Games (e.g. the Civilization and X-COM series) typically allow players to take in comments from those nearby while still being able to play without being handicapped.
While the game Backseat Gaming may seem to directly point towards supporting Backseat Gamers, it actually refers to the fact that the players of the game sit in the backseat of cars. This does however not stop the other passengers, including those sitting in the front seats from being Backseat Gamers.
Using the pattern
The primary requirement for Backseat Gamers to be possible is only that the game can have Spectators. One way of modulating the pattern is to allow Drop-In/Drop-Out gameplay - this way people can move between being Backseat Gamers and being actual players (which is a way to support Tiered Participation in a game).
The difference between Non-Player Help and Backseat Gamers is mainly in the awareness of "non-players" if they are affecting a game.
Supporting Backseat Gamers does require some way for people besides the players observing the gameplay. This is typically not a problem with traditional Board Games or those co-located with players of Computer Games. Although not common, hypothetically Computer Games could support Backseat Players not near the actual players by having specific Spectator views and Communication Channels between the Spectators and the players.
Backseat Players may disrupt the social agreement a game instance is based on. This since the extra help may be perceived as cheating. While not necessarily noticeable in Mediated Gameplay, this makes the pattern easily come in conflict with PvP for games that have Unmediated Social Interaction.
