Story
After years of planning, Dr. Eggman's plan of global domination has finally been completed. He's built a machine called the "Dimension Mixer" that will mix up dimensions from all across the universe! With this contraption, he'll be able to rule every corner in the universe with an iron fist, and bring Eggmanland back to its former glory! In order to test this new creation out, he took it to Green Hill Zone on South Island, where Sonic and his friends just happened to be at that very moment. Everything seemed to be going as planned, but when Eggman activated the Dimension Mixer, it spiraled out of control, not only sucking in Green Hill Zone but also many locations that Sonic had visited over the years, and even the rivals themselves! Soon, everything was black... there was no telling as to what was going on... until they came to.

About 10 minutes later, Sonic - along with Tails and Knuckles - woke up and soon made a shocking discovery: EVERYTHING WAS MIXED UP! Green Hill was mixed with Emerald Hill, Seaside Hill with Tropical Resort, it was all a mess! Even places from Blaze's world were caught in all the madness. What had Dr. Eggman done this time?! Not wanting to let this slide, the heroes braced for action once again and sped off into the void, hoping to return everything back to the way it was before this foul scheme had officially commenced.

After blasting through the crazy mishmash of Green Hill, Emerald Hill, and Leaf Storm, they eventually find Dr. Eggman, who was surprised everything worked out the way it did, albeit with him being sucked in too. It was then after discussing just what on Earth happened that the truth was revealed: Eggman could rule every dimension from inside his own machine! This enraged Sonic and his friends, which prompted a quick boss battle against a familiar machine from the first adventure 30 years ago.

After a swift defeat, Eggman revealed the truth behind the whole operation and about the whole plan to bring back Eggmanland. Furthermore, he said that he was feeling generous, and gave the heroic trio 3 days to revert everything back to the way it was before. Should they succeed, he would leave them in peace and give up on the whole operation. If they failed, Eggmanland would finally return to the world, and everything would be ruled with an iron fist, including Sonic and his friends themselves! And with that, he zoomed away, leaving the heroes clueless as to where they would go next. Just then, the ground started to shake and move as the 3 zones they went through separated and flew out of the Dimension Mixer. It was revealed to them that if they ran through every mashed up place inside the machine and defeat Eggman in them, the locations will separate and fly out of the machine. But they had 2 important questions on their minds: Thanks to the genius of Tails, they able to create a little map as to what locations were where and how much time they had left to save everything they knew and loved. There were 7 other mashed up areas throughout the Dimension Mixer, and they found out that there was no time to waste. They soon high-tailed it to wherever the next location was, determined to save their world, as well as various others throughout the universe.
 * 1) How many more locations are there to save?
 * 2) How much time do they have left?

(The player has control as to where Sonic/Tails/Knuckles goes next. The next 7 zones are now unlocked and can be played in any order, but must be cleared before the 9th and final zone of the story can be unlocked.)

After the 8th zone has been cleared, the trio soon chases Eggman into the final mashed up area that, somehow, wasn't able to be tracked by Tails. They soon made a grim discovery: The Death Egg has been rebuilt yet again and is about to be launched into space!
