Step-by-step walkthrough

The complete route is still being worked out. Only the opening moves below passed the current checks; they do not establish a full solution. Bombs are shown at their saved positions; their effects and timers are not included in this candidate. This candidate assumes a clamp opens when its paired bar leaves; confirm this behavior in the game.

  1. Move S3 right along its track about 3.86 ring radii. Continue until the bar leaves the board. Release and wait. Expected departure: S3. Expected remainder: 14 rings, 6 bars.

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 →
Bomb Ring
Carries a timed bomb and can clear other rings. Deal with it before the countdown ends.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 →

The complete route is still being worked out. Only the opening moves below passed the current checks; they do not establish a full solution. This candidate assumes a clamp opens when its paired bar leaves; confirm this behavior in the game.

  1. Rotate Ring 10 counterclockwise about 98°. Target opening direction: 333° (right 0°, up 90°). Release and wait. Expected departure: Ring 10. Expected remainder: 15 rings, 5 bars.

  2. Rotate Ring 2 clockwise about 82°. Target opening direction: 8° (right 0°, up 90°). Release and wait. Expected departure: Ring 2. Expected remainder: 14 rings, 5 bars.

  3. Rotate Ring 3 clockwise about 150°. Target opening direction: 50° (right 0°, up 90°). Release and wait. Expected departure: Ring 3. Expected remainder: 13 rings, 5 bars.

  4. Move S3 up along its track about 5.71 ring radii. Continue until the bar leaves the board. Release and wait. Expected departure: S3. Expected remainder: 13 rings, 4 bars.

  5. Move S4 left along its track about 4.43 ring radii. Continue until the bar leaves the board. Release and wait. Expected departure: S4. Expected remainder: 13 rings, 3 bars.

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 →

Frequently asked questions

Which board should I use for level 78?

This page has 9 distinct boards. The default A board has 14 rings and 13 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 78?

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.
