Blockade (1976) by Gremlin is the original snake game: two players steer ever-growing trails and try to make the other crash first. Nokia's Snake descends from it.
Each player in Blockade controls a line that never stops moving and leaves a solid wall behind it; crash into any wall, your own trail or your opponent's and you lose the round. Gremlin Industries treated it as a simple two-player game, but the idea proved almost endlessly reusable. Atari cloned it as Surround for the 2600, and the concept was reimplemented thousands of times afterwards — most famously as the Snake game on Nokia mobile phones.
Blockade was developed by Gremlin Industries in 1976 and is the origin of the snake game concept. Two players control continuously moving lines that cannot stop or turn back on themselves. The player who crashes into a wall or the opponent's trail loses. The concept was so clean and compelling that it was immediately cloned by competitors and has been reimplemented thousands of times, most famously as the Nokia Snake game in 1998.
