Special Stage
Chaos Emeralds are collected when you successfully clear the Special Stages. If you have 50 Rings or more, find Tails or Knuckles who will be standing by somewhere in the ACT. Once they collect all of your Gold Rings, you will be transported to the Special Stage.

Grab as many Rings as you can in order to advance to the next section of the stage and to finally earn the Chaos Emerald. The stage will end before you’ve reached the goal (Chaos Emerald) if you fail to collect the required number of Rings for each checkpoint, or touch the spiky metal balls with no Rings in possession. When the Special Stage is over, you will return to the ACT and carry on from where you found Tails or Knuckles.
