Sonic Labyrinth is a puzzle-platformer video game released in 1995 for the Sega Game Gear. Unlike traditional Sonic titles known for their high-speed gameplay, Sonic Labyrinth focuses on strategy and puzzle-solving, stemming from Sonic's loss of his usual speed. In the game, Dr. Robotnik tricks Sonic into wearing the Slow-Down Boots, impairing his mobility. Players must navigate through a series of isometric mazes, collecting keys to progress through the levels while overcoming obstacles and enemies. Despite its departure from the usual Sonic formula, it remains a unique entry in the franchise's history.
