Path maker

Spoiler: Hints

1. Three hidden draggable in the ground.
2. Two balls are useless.
3. Two grass blocks that can't walk on.

Spoiler: More hints

1. Position of two balls: one is near B at the beginning. One is in the middle of the sand at the edge.
2. Position of two grass blocks: one is on the left side near the sand, to make R turn right. One is on the left side near a draggable, to prevent shortcut.
3. One hidden draggable is under the small tree.

The logic behind building a long route for R is EXCELLENT! I really like this type of level; you can think for a long time without rushing or stress. I love it.

But! Your description is incorrect – you have three tricks.

Spoiler: Tricks

"1) Low ceiling
2) Tap cancel (without it, it's impossible to push multiple balls correctly!)
3) Eye elevator (that's also a trick!), On top of all that, it's also hidden! Hiddenness is also considered a trick by some."

So this is definitely a trick level!!!

I see that you wanted this level to be gimmick-free—and I support that desire! I think this level would be better without gimmicks. They're completely unnecessary and unimportant here, and it's easy to do without them:

Spoiler

"1) put a single wedge instead of a stair

2) make the trees taller
3) just make impassable cells instead of hidden eyes.
It's a good thing I read your hint, because without knowing where the impassable grass is, it's impossible to construct complex logic. I had to run around looking for these invisible, impassable grass blocks, wasting a lot of time and an unnecessary restart. Overall, I think it's much better without the hidden grass!

I really appreciate your levels, so I decided to take the time to give you some advice. Sorry, but it's out of great respect for you and your talent.

The logic is amazing. I really enjoyed
it. Thank you.

@Denis Nazin Thanks for playing and writing such a detailed advice! I will express the tricks required more correctly next time. About the two impassable grass, one beside the draggable is to prevent shortcut and I think it's unnecessary, so I use eye elevator. The other I choose to use eye elevator is because I want to make it harder, but obviously it's way too hard. It's my bad. Thanks for your useful advice and your appreciation!

When none of my plans worked, I tried to win it in a strange way. But you have placed the eye elevator in the right place, which makes it impossible.I have thought about it many times but have not yet succeeded in finding the right path.

Bwoah this was difficult. Your diversions of intuition are very effective. I was encouraged by the review of @Denis Nazin; "there must be a logical solution!". I agree with his suggestions of improvements. Beyond that balls may easily roll off line, but that's inherent to balls on rails, which you need to make the level complicated (so many possible directions). Contrary to my feelings of frustration I had along the way of figuring this level out, you did a great job on creating a complicated R path level.

Note: positions of the balls in this screenshot are completely wrong. The annotations are the plan.

Red line: R's path.
Blue arrows: B's ball pushes.
Purple arrow: R's ball push.
Turquoise crosses: dummy ball positions (don't touch).

@Block builder Thanks for playing! Your image solution is completely right and detailed, and I'm so glad you like this level. I really spent a lot of time on designing and revising this level, to make it more difficult and diverse.

@Kanchan yadav Indeed this is a really difficult level, and I put two eye elevator which make it more harder. You can look at Block Builder's comment which gives the right solution

@EinaUdi I want to do it myself, that's why I don't want to see map completely yet.

@Kanchan yadav Then you can see the hints if you can't finish. Mind that one eye elevator is at the left side of the sand, just beside the hole. Use logic more to speculate R's route. I believe you can pass it

@EinaUdi I did not know about this, so I checked it now.

I won by using the path shown by @Block builder . I never understood the eye elevator for R's path.A great level and a great design.
If the ball has low ceilings, a cancel tap becomes mandatory.

@Kanchan yadav Thanks for playing! Actually I shouldn't have put that eye elevator for R's path which made the level too difficult. I should put an impassable block instead of it. Glad you like the whole level

This is a really good level of R logic that's really made me think. And I love that. The design is great too. But I'd like to mention a few things...

Spoiler

It's true that pushing the balls was a bit annoying because even using cancel tap, sometimes they'd veer off in the wrong direction, but oh well, I understand that as part of the challenge. The unnecessary balls weren't a problem for me because I figured it out myself when I saw they were leading R down dead ends. But the impassable blocks were a real headache because you couldn't see them until you freed R. Perhaps putting a different block in those specific spots (in this case a red brick, for example)would make players think there must be a reason for it and try to figure it out.I know that information was in your hints, but I don't usually read them so I can figure it out for myself.

thanks @EinaUdi great job!
