Step-by-step
Start at the short exposed top and bottom 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 left and lower outer frames, then work through the parallel upright bars. 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 remaining tall blue, orange and purple bent bars one at a time. 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
- Start at the short exposed top and bottom corner bars.
- Release the left and lower outer frames, then work through the parallel upright bars.
- Finish the remaining tall blue, orange and purple bent bars one at a time.
- After every release, check which pieces are still connected; color alone does not determine the move order.
Common mistakes
- Do not rotate every sleeve together; follow the individual bar that is actually being released.
- Repeating the same rotation without checking the opening and the remaining contact.
Frequently asked questions
How do I start Rotate Rings level 21: Nested rectangular bars with silver sleeves?
Start at the short exposed top and bottom 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 21?
Release the left and lower outer frames, then work through the parallel upright bars. 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?
Do not rotate every sleeve together; follow the individual bar that is actually being released. For the finish: Finish the remaining tall blue, orange and purple bent bars one at a time. Move one remaining piece at a time and wait for its release before deciding whether another contact still needs attention.
