- Ring
- An open ring can rotate. Align its opening with the connecting pin to release that connection. Rings fly away automatically once their connections and constraints are released.
- Blocking pin
- A fixed pin sitting on a ring's edge. It holds another ring in place, so its gap has to face this pin.Read the mechanism guide →
- Stop pin
- Limits how far a ring can turn, so only part of the ring is reachable.Read the mechanism guide →
- Latch
- Holds a ring in place. A stick locks it, so release the stick first and then turn the matching ring.Read the mechanism guide →
- Stick
- Slide bar. Move it sideways to release the latch it is tied to.Read the mechanism guide →
- Closed ring
- A closed ring has no opening. Release its blocking connections using the surrounding objects; the ring flies away automatically when it is free.Read the mechanism guide →

- Ring
- An open ring can rotate. Align its opening with the connecting pin to release that connection. Rings fly away automatically once their connections and constraints are released.
- Blocking pin
- A fixed pin sitting on a ring's edge. It holds another ring in place, so its gap has to face this pin.Read the mechanism guide →
- Closed ring
- A closed ring has no opening. Release its blocking connections using the surrounding objects; the ring flies away automatically when it is free.Read the mechanism guide →

Read this board before making a move
- Ring
- An open ring can rotate. Align its opening with the connecting pin to release that connection. Rings fly away automatically once their connections and constraints are released.
- Blocking pin
- A fixed pin sitting on a ring's edge. It holds another ring in place, so its gap has to face this pin.Read the mechanism guide →
- Closed ring
- A closed ring has no opening. Release its blocking connections using the surrounding objects; the ring flies away automatically when it is free.Read the mechanism guide →

Frequently asked questions
Which board should I use for level 77?
This page has 9 distinct boards. The default A board has 15 rings and 15 blocking pins. Compare these features and the thumbnails before following its steps.
What do the numbers on the diagram mean?
They identify individual rings, not the operation order. A written step can also describe a bar or latch, so the step number is not always the ring number. Match the ring number named in the instruction with the diagram.
What should I check when I am stuck on level 77?
Check whether the ring is open or closed, whether a stop pin limits rotation and whether a latch is still locked by a bar. Repeated rotation does not remove a fixed obstruction. Compare the neighboring connections, then return to the step for the matching ring number.
