Snake is the common name for a video game concept where the player maneuvers a line which grows in length, with the line itself being a primary obstacle. The concept originated in the 1976 arcade game SnakeBl, and the ease of implementing Snake has led to hundreds of versions (some of which have the word snake or worm in the title) for many platforms. After a variant was preloaded on Nokia mobile phones in 1998, there was a resurgence of interest in the snake concept as it found a larger audience.

The player controls a dot, square, or object on a bordered plane. As it moves forward, it leaves a trail behind, resembling a moving snake. In some games, the end of the trail is in a fixed position, so the snake continually gets longer as it moves. In another common scheme, the snake has a specific length, so there is a moving tail a fixed number of units away from the head. The player loses when the snake runs into the screen border, a trail or other obstacle, or itself.

The Snake concept comes in two major variants:

In the first, which is most often a two-player game, there are multiple snakes on the playfield. Each player attempts to block the other so he or she runs into an existing trail and loses. Surround for the Atari 2600 is an example of this type. The Light Cycles segment of the Tron arcade game is a single-player version where the other "snakes" are AI controlled.

In the second variant, a sole player attempts to eat items by running into them with the head of the snake. Each item eaten makes the snake longer, so controlling is progressively more difficult. Examples: Nibbler, Snake Byte.
