Snafu

Snafu was the game anticipating Tron light cycles by a year: snakes leaving trails that had to avoid crashing into walls, trails and opponents. With two players it became psychological warfare: trapping the opponent by cutting their path, forcing them into dead ends, sacrificing space for position. 16 variants changed speed, rules and AI behavior. Intellivision's 16-position disc made movements smoother than any Atari clone. Snafu was the perfect competitive party game — quick, brutal, and friend-argument generator.
