Blockade is a monochrome arcade video game developed by Gremlin and released in November 1976. It was the first of what became known as "snake games". It was designed by Lane Hauck, Ago Kiss, and Bob Pecarero. In Japan, it was distributed by Taito in 1977 as "Barricade II".
Using four directional buttons, each player moves their character around leaving a solid line behind them, turning at 90 degree angles. To win, a player must last longer than the opponent before hitting something, with the first person to hit something losing. The game ends after one player gains six wins.
Blockade was first demonstrated at the AMOA show in November 1976. It was one of the two most talked-about arcade games at the show, along with Namco's electro-mechanical racing game F-1 demonstrated by Atari, Inc. Blockade was possibly the most-played arcade game at the show. Play Meter praised the simplicity of the gameplay.
Midway's Tron (1982) included a single-player variant of the Blockade concept based on the Light Cycle game from the film. The player battles against one computer-controlled line-drawing cycle, and three on subsequent levels. This led to Blockade-style games sometimes being called Tron or light cycles.
