Stair builder 3

Nicely done! This is probably the trickiest of the three, but it has a wonderful surprise halfway through that I did not expect. Great fun to play and very satisfying to solve.

Thanks a lot to the players who tested it !

Spoiler: Hint 1

Visual hints will help finding the good combination.

Spoiler: Trick needed

Autopilot.

Spoiler: Hint 2

You should make a path to the center of the stairs, then use this path to go somewhere else.

@Star Penguin Thanks ! Tricky and puzzling... What have I done ?

@vince You have made a masterpiece, that's what you've done.

Ful-der-won!

What @Star Penguin said the first time...

Spoiler: ?

I'm not sure what am I missing. I follow the Visual hints and move the sticks to their locations. When others "sticks" are in place, there are always two "sticks" in adjacent corners ) that is swapped....

@TR O You have probably swapped the two sticks of identical height. There is one with a pillar on top, the other is a half pillar. The hints are also showing it

@TR O

There are two sticks of equal height that need to be in the right order. Otherwise it won't work elsewhere. Is this what you mean?

Edit: what @vince said at the same moment.

Yeah you guys are right. But I tried to swap but it just become the other two sticks instead of those two... They just don't go away. What to do...

@TR O I have the following strategy to put every stairs in order: I put one piece on the right place, then the other next to it, one by one always in the same way (going clockwise for example). The last two pieces should go in the right place automatically. I don't know if that helps...

Spoiler: ???

Is this right?I've tried different things and going clockwise too...but doesn't see anything go to right place "automatically"

@TR O The solution is to make a path to the center :

Spoiler: Next step

Then use this path for autopilot
