Not ignoring levels @Lang Tao Jin ,I'm only doing B only levels at the mo.

Sorry i can't understand. is there a video?

I have failed to get one star that i had hoped a swerving B might have captured but in this challenging level i think getting the autopilot for B and moving R to the winblock are good enough results.

@ridgerunner
I can't figure out how to get to the two free columns at all ?? I sent the R up, took the star inside, the second ball on the top doesn’t roll to the star? What's next I don't understand at all? All autopilots do not reach the island with free columns. Please record a video of your victory. It is very interesting to me!!

For some reason the author did not answer me

@Denis Nazin .. here is a video of the vital enhanced autopilot. I didn’t bother putting R into position to save time.

Spoiler: Vital move video

@ridgerunner
Thank you very much!!! I am very grateful to you! Because I have been puzzling over how to do it for a very long time. But I am very upset. Because I wasted a lot of time.

I would never solve this hidden autopilot puzzle.
Even after I watched your video, for a long time I could not understand why B goes this route. It turns out there is a path under the ground which is absolutely invisible! Before that, it is unrealistic to guess! I don’t understand how you understood that ?! But besides that, you need to make a preparatory autopilot to put B on a wedge! To do this, you need to understand that this is the starting position for the autopilot. This is unrealistic !! Moreover, the author did not indicate that there are tricks. I tried to get through for a long time without a trick.

@Denis Nazin ..how i worked out the finish.

Spoiler

the steps and opening in line with the two free columns above indicated a likely autopilot that would also have B travelling along the top of the fencing. I thought that it was likely to be initiated somewhere B doesn’t normally have access to as there were no obvious steps that are often the start of these autopilots. So i decided the line of wedges between the stairs was a good place to try and i tried the bottom wedge first.

@ridgerunner
You have amazing intuition. But this can only be guessed by chance and tried as you do. It is unrealistic to see the solution logically. I even had to think about your ready-made solution. It seems to me that many will not be able to understand even your video.
