Dr. Robotnik has converted Mount Mobius into a giant fortress, powered by the Chao Emeralds. So Sonic and Tails fly on the biplane to put a stop to it. On the way there, the biplane is shot down and Sonic lost at sea, only to find his way into the fortress from the sewers underneath. Starting from there, Sonic makes his way through the fortress, collecting the Chaos Emeralds along the way to stop Dr. Robotnik.
The game is played across 4 different worlds, each a large pinball maze in which Sonic must collect all the Chaos Emeralds in the level to unlock the boss room. Upon finishing each level, the player can play a bonus level which works like a small pinball table which Sonic is at the control of. These bonus levels feature characters from the Sonic the Hedgehog animated series.
