- 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 →
- 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 →

- 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 →
- 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 →

Frequently asked questions
Which board should I use for level 74?
This page has 9 distinct boards. The default A board has 17 rings and 17 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 74?
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.
