According to Polygon, Sonic Mania has at least 32 giant rings hidden throughout the game's 12 zones. A skilled player could collect all 7 emeralds before even finishing Studiopolis Zone.
What would happen if I found a giant ring after collecting all 7 Chaos Emeralds?
Would the remaining giant rings still appear? Or would they all despawn after every emerald had been collected?
Best Answer
Yes, they still appear.
Collecting a giant ring gives you 50 rings, which incidentally is what you need to become Super.
This is also how it worked in Sonic 3 and Sonic and Knuckles.
