video game
A video game or computer game is an electronic game that involves interaction with a user interface or input device (such as a joystick, game controller, controller, computer keyboard, keyboard, or motion sensing device) to generate visual fe ...
from scratch.
Depending on the format, participants might work independently, or in teams. The event duration usually ranges from 24 to 72 hours. Participants are generally programmers, game designers, artists, writers, sound designers and others in game development-related fields. While many game jams are run purely as a game-making exercise, some game jams are contests that offer prizes. Some submissions were eventually released as fully-developed games.
Traditionally, game jams focus on video games;

Prior to game jams, there were rapid creation challenge events such as the Interactive Fiction Competition starting in 1995 and a writing challenge NaNoWriMo from 1999.
The earliest known game jam is SpeedHack, which began in 1999 and ran until 2015. SizeHack 2000 is another early jam.

0th Indie Game Jam
Retrieved February 5, 2013. This is the first documented use of the ''game jam'' name.
Ludum Dare (since April 2002), and
LT Game Jam (since August 2002) are other game jams that originate in this period. These 2002 game jams focused on the technology and the programmer. Many participants joined by themselves, and the Indie Game Jam and LT Game Jam required that the programmer use a custom game engine. Ludum Dare initially described itself a "competition" and now offers jams and competitions as distinguished events.
The
Nordic Game Jam was first held in January 2006 and introduced the model with group forming and theme introduction prior to the jamming period. This would later be adopted and popularized by the
Global Game Jam (since 2009), orienting game jams towards team collaboration. Game jams also became distributed or organized for a cause, examples being the Health Games Challenge (2010) and the Fukushima Game Jam (2012), respectively. Beginning with the
Train Jam (2013), game jams joined the
experience economy.
At least 1290 game jams were held on
itch.io by 2013.
Format
Location

Some game jams are local events, taking place in universities, conference halls, or other private spaces.

Global Game Jam takes place at the end of January of every year, with over 800 locations in 100+ countries around the world. The
Ludum Dare is an example of a virtual game jam, an event where participants largely remain at home, but present their efforts at the conclusion of the jam.
Time constraint
Game jams typically have restrictive time limits, ranging from a few hours to several days. This time constraint is meant to simulate the pressure of a deadline and to encourage creativity among ideas produced by game jam teams.
Theme
A game jam may be centered on a theme, which all games developed within the jam must adhere to. The theme is usually announced shortly before the event begins, in order to discourage participants from planning for the event beforehand and from using previously developed material.
In addition, themes are meant to place restrictions on developers, which encourages creativity.

Ludum Dare 24, a competitive game jam event, featured the theme of "Evolution". As stated by the Ludum Dare rules, all participants in the competition were recommended to create a game based on this theme. However, the rules also stated that participants were not required to use the theme, which allowed for games to be made outside of the theme.
Technology
The type of technology can vary depending on the type of game being developed, and among the different disciplines involved.
In a video game jam, teams are generally made up of at least a programmer and an artist.
A programmer build using game development tools. It should allow rapid prototyping to meet the time constraint. An artist may use creative tools to produce the game assets, or they might use those that come with tools such as

s. Some definitions exclude competition-focused events from game jam, such as Grace (2016) and Ludum Dare, arguing that game jams emphasize the process over the product. However, it is not clear where the line should be drawn.
* Commercial game jams – In
Amnesia Fortnight, teams build ideas with most votes by people. People vote and receive the prototype for a fee, making the event an example of commercial game jam. Game jams have also been held to promote products and companies.
*
Experience economy – Game jams were held on train, sea, and air travels, and at locations such as cabins without ample water and electricity infrastructures and castles. These provide experiences unique to normal game development.
* Games industry commentary – Certain events in the industry have spawned game jams, such as removal of ''
Flappy Bird'' leading to Flappy Jam.
* Meta – Some game jams comedically use the elements of game jams itself, such as the 0h Game Jam held during the last hour of

themes to introduce them to under-represented groups. A survey also noted game jams as a way to teach game development career and social skills.
In classroom, game jams promote team work, creativity, planning, problem solving, and diversity. Educators may further mix social exercises such as "circle flap", "social ball", and "name gesture". Together with physical prototyping, they engage team communication.
Meanwhile, the participants joined game jams to learn skills, network with others, and have fun. A study found that participants improved their social skills after a game jam. The time dedication needed was often a reason for not attending a game jam for university students.
Long-term programs that span over several weeks does not work well with their schedules.
Games
Many games started as projects for game jams. For example, ''
Surgeon Simulator 2013'' was a submission for the 2013
Global Game Jam. From heartbeats as the event's theme, the developers conceptualized a
heart transplant game with "quite challenging" physics and tools. The game quickly became popular following the release to the game jam. The popularity lead to a full version release on
