HIDDEN EASTER EGG GAME on SEGA MASTER SYSTEM

On the original Sega Master System there was a hidden Easter Egg game called Snail Maze. It has 12 levels and each level carries forward the unused time. It can get quite challenging and was a nice touch from Sega.

That is because your SMS is running the 1988 firmware. On the 1986 firmware when it boots up, there are instructions on how to start snail game, which was the only built-in game 🐌
