Snafu is an arcade-style main game from 1981 where players engage in high-speed, competitive maneuvering across 16 variations. The core loop involves either creating trapping mazes by extending a moving trail to force opponents into collisions (Trap Games) or directly attacking rivals by maneuvering your serpent's head to bite off segments of their tail (Bite Games). Survival demands constant motion and strategic blocking or aggressive pursuit.
The gameplay is divided into two primary modes of competition, offering significant replayability through its structured variations. Players must strategically navigate a confined space, either creating walls or engaging in direct tail-biting combat. The game features 16 distinct game variations in total.
In these modes, the objective centers on environmental control. Players guide a moving trail, and the goal is to maneuver in such a way that the opponent (human or computer) collides with an existing trail, the boundary of the playing field, or static obstacles within the maze. A collision results in the elimination of the colliding trail. Maintaining your own trail's continuous motion without self-collision is paramount while simultaneously engineering traps for the opposition.
This mode shifts the focus to direct serpentine conflict. Players control a hungry serpent, and the objective is to make contact between the head of your serpent and any segment of the opponent's tail. Each successful contact "bites off" one link from the opponent's length. The winner is determined by being the last serpent surviving on the screen.
The unique appeal lies in its dual focus on strategic maze construction (Traps) and direct, length-reducing combat (Bites), all executed with a requirement for constant, unbroken movement. It merges elements of line-drawing strategy with high-speed reaction challenges, where the environment itself becomes the primary weapon.
As a main game title from its initial release era, there are currently no officially released downloadable content (DLC) packs or expansions associated with this title.
