Snail Maze

Snail Maze is a 1986 video game by Sega for the Master System. Instead of being released on a cartridge, it was built into the system's BIOS and could be played by starting the system without a game cartridge inserted and holding Up and buttons 1 and 2 simultaneously.

A very simple game, Snail Maze involves navigating a small orange snail with a yellow shell through a blue maze. A goal area is clearly marked, which players must attempt to reach within a time limit. Despite its relative simplicity compared to other games of its era, Snail Maze could be quite challenging. Subsequent levels reduce the time available, giving a progressively lower margin for error.
