1 of 4!

I kept getting B stuck in the holes by the FDs

@Chris Hester No FD there.

Thanks for the level! At first, I did not understand what needs to be done so that B can pass to the win. But then I still found a very cunningly hidden hint. Thank you very much. I am very interested in what is the secret - why the ball can only fit to one of the eyes? This is your very interesting find!

Spoiler

I must be missing something because the trick move only triggers claustrophobia on the first ball. B can`t get over the remaining 3.

That`s what I thought. But no matter what order I use, only the first ball can be passed. And it doesn't matter which ball I put in the first position. They all produce the same result.

@Denis Nazin @cimarronline @Don G Rowe If you look inside you will see eyes embedded in the motor (movable block).

To make it we must know about how to read the order of blocks in the game and about two blocks in 1 cell.

Why is only the first eye always passable? because the eye is not embedded in the motor (so the eye is a fixed block). I assume all fixed blocks will be read first than movable blocks. so the eye effect is not active.

I set it up like that so that there is only 1 passable way out of 24 ways. This is a permutation.

@cimarronline Yes, half of the eye and the ball are in 1 cell. It's like an elevated eye.
Motor is used as a movable block of the eye. The block property that takes priority in a cell is the last read. Like your explanation (win block) on the star pass thread.

@cimarronline Yes, that's the explanation, if true fixed blocks is read first (because this is just my opinion). Thanks for the demo above.

Four stars for the engineering +1 for the coding. Nicely done.

Oh I made a mistake, for the eye and zapper. Although physically lowered, but the effect fills 1 cell at the top. That's why the elevated eye/zapper works.
