How stars and saved progress work

Every stage in the browser campaign offers up to three stars, 36 in total. You only need to complete a stage to unlock the next one, so stars are a reason to come back rather than a barrier.

Running stages

1. Reach the finish.
2. Finish with at least the stage’s ring target. The target is checked against the rings you still hold at the finish, not the total you collected.
3. Finish with all three shields.

Because an ordinary obstacle hit removes one shield and up to ten rings, a late collision can cost you two stars at once. A short protection period after a hit prevents an immediate chain of further hits.

Ring targets

Boss stages

1. Defeat Eggman.
2. Finish without missing an attack opportunity.
3. Keep all three shields.

Stages 8 and 12 have no ring target.

Where progress is saved

Stage unlocks and results are stored locally in the browser you play in. They do not sync to another device or another browser on the same device, and clearing this site’s stored data can remove your records. There are no accounts or cloud saves.

Practice does not count

Practice mode — Sky Bridges, Magnet Meadows with a temporary Ring Magnet charge, Coastal Arrival and Eggman Encounter — does not award campaign stars, unlock stages or permanently grant Ring Magnet. Complete the campaign stage itself to keep the reward.

A practical order for 36 stars

• Clear the campaign first, taking the safe routes.
• Return to the short stages — Totem Gates and Coastal Arrival — for three-shield finishes.
• Use Ring Magnet on Magnet Meadows and the later coastal stages for ring targets.
• Leave Sky Bridges’ 130-ring target for last; it asks for the most risk.
