Step-by-step
Open the lower-left frame and exposed upper corner bars. Find the actual gap on this piece before turning it. Follow its contact with the neighboring link, rather than assuming the colored outlines form one object. Make a small controlled rotation and check whether the connection has released before selecting another part.
Release the middle purple and blue bends before approaching the upper green ring. Reassess the structure after each release: a piece that looked trapped at the start may now have only one neighbor. Use the empty area to see the next contact clearly. Follow the branch described here instead of jumping to a similar color elsewhere.
Finish the last purple curved link beneath the upper green branch. Watch the final connection as well as the open ends. A nearly empty board can still contain a linked pair, so keep aligning the gap with the remaining contact. Stop repeating a turn that changes nothing and inspect which neighboring piece still holds the chain.
Tips
- Open the lower-left frame and exposed upper corner bars.
- Release the middle purple and blue bends before approaching the upper green ring.
- Finish the last purple curved link beneath the upper green branch.
- After every release, check which pieces are still connected; color alone does not determine the move order.
Common mistakes
- The two U-shaped frames have different inside attachments, so one open end does not free both.
- Repeating the same rotation without checking the opening and the remaining contact.
Frequently asked questions
How do I start Rotate Rings level 309: Two U-shaped frames linked through a green middle chain?
Open the lower-left frame and exposed upper corner bars. Match this branch by its position and shape before moving. If your starting arrangement differs, compare the video with your board rather than forcing the same sequence.
What is the key transition in level 309?
Release the middle purple and blue bends before approaching the upper green ring. Keep watching the contact points as the structure shrinks. The next release depends on what remains linked, so recheck the gap after a neighboring piece disappears.
What can block the finish in this layout?
The two U-shaped frames have different inside attachments, so one open end does not free both. For the finish: Finish the last purple curved link beneath the upper green branch. Move one remaining piece at a time and wait for its release before deciding whether another contact still needs attention.
