How do you get special stages in sonic rush?

You get to the special stages in Sonic Rush by collecting 100 rings in a regular stage.

Here's how it works:

1. Collect Rings: As you play through the game, gather rings by collecting them from the environment or destroying enemies.

2. Reach 100 Rings: Once you have 100 rings, a special stage portal will appear.

3. Enter the Portal: Run into the portal to access the special stage.

Important Note: The special stage portal will only appear if you have 100 rings at the end of a stage. If you have 100 rings and die or reach the end of the stage without them, you won't get access to the special stage.
