Oh very cool map. I solved it the intended way - to my surprise!

i think i solved it the unintended way because i skipped the entire left half (from the workshop picture's perspective) of the chamber

People, stop complaining about having to redo sections of chambers when a mistake is made. QuickSave and QuickLoad, that's the solution.

@warkosign I solved it that way too. :D

Found an unintended solution: https://youtu.be/HXqisbnHrXE

Smart puzzle, but GOD was it annoying to execute. There is a problem with the portal placement on the angled surfaces, and every time it fails you gotta redo the whole routine. Took me like 5 or 6 attempts after realizing what I'm supposed to do.

Also, you can remove the portal surface on the celling, it only enables the cheese and you can get back from the high place simply by portalling up and catapulting yourself over the goo, so It's completely unneccesery.

Great level. I also found the skip first, but then went back and found the proper solution, too. Excellent puzzle!

It took me A HOUR!!!

You just gave me a headache for this weekend and lifelong migraine.

Great!

could be a fun map, but ruined by wonky portal hit detection on the angled white surface. i've already found the solution but it took me 5 tries to finally execute it.

10/22

Hehe, I found the skip too. I don't know what the intended solution is, but I was working backwards from the goal, and the skip was the first thing I thought of.

That's the concept of a wormhole inside a video game:

Using different areas of the map as if they are not separated from each other. And that's exactly the concept of a wormhole. Distance does not matter anymore. You can use everything any time, as long as you can get to it in some convoluted game. Boy do I love Portal for these kind of puzzles! It feels so good to play them.

This chamber in particular got me thinking about how ingenious the concept of a Portal wormhole is, and all the implications that I never thought Portal could be.

I always try to recapitulate in the end, how everything is connected and WHY it worked in the end. And here, it gets heavy to keep everything in the mind.

Everywhere you can walk, you can extend/move your Portals. So as long as you can get back in the end, you can place your Portal down there. But to get there, you have to change sides of the map so often - if you think how in the end you fly from the top left of the chamber to the angled surface over the water pit to the other angled surface and then back up again, only to keep momentum there and at the same time in the air, get your Portal to the "home" area, that's peak Portal to me.

One way to prevent the skip would be to remove the portal panel on the ceiling, and instead provide wall portals on the side that enable you to fling yourself back. That way, you can't get to the "starting area" without losing a placed portal - you can't carry it there.

Regarding the comments saying that only solutions should be provided that allow you to fling between two portals endlessly and think about the next step: That would sadly be limiting many ingenious solutions. That's the reason why I love this series: It forces me to think about portal placements and movements beforehand, and execute them at once. In so many Portal trailers and promotional videos you see that careless flinging and the momentum you feel doing it. But Portal chambers never have forced me to play that way, so I've never felt it.

oh looks like other people already mentioned it, nice

I found an alternate solution where you only use the room with the three levels; I put portals on the floors of the first and second levels and fell through the first level one to get momentum then put a portal on the ceiling surface across the goo just before backing up to get to the third level, then put a portal on the wall surface on the third level and went through to get across the goo and replaced the ceiling portal with a portal on the exit slanted surface, went through, replaced the wall portal with one on the first level then fell through it and got to the exit

I really liked this! You have to weave through the angled portal surfaces like weeee!

It is fun and hard,takes me a lot of time to pass it.

This had me "stumped" for way too long, turns out I just wasn't doing it the way the map wanted me to...

The central move is clever, but executing it is unspeakably annoying. I'm not sure what's up with the setup of these portal placement helpers, they almost seem anti-helpful because they don't match each other properly on both panels across the whole thing. I tried the move at first, thought it was impossible and only returned to making it work recently.

Thumbs up for cleverness, but it's the first thumbs up in the no elements series that I hesitated with.

Awesome.

Nice one. Pretty easy, but still good fun.

Cool beans man, wasn't that hard once I thought about it.

This was really hard for me. I gave up and watched the walkthrough. Very good and challenging map with advanced tecniques.

That's sick.

Continued: Go through it, place a portal on the lowest portalable surface below you, jump through and you're away!

I think I cheated this lol. The only angled panel I used is the one for the exit.

Portal up to the highest level in the map. On the portalable floor below you, place two portals and bounce in them up and down. When you come out of a portal look at the ceiling across from you, there's a portalable surface there. Place a portal on there (this is tricky!) and get back up to the highest level again, this will be possible when you reach your highest point from the portal. Place a portal in front of you so that if you go back through it at a later time you'll be at the highest point again. Go over to the exit room and place a portal on the angled panel.

im learning got ths one on my own. great job!

That was tough! But there is an easy way to execute it. Hint 1: fly between slanted panels to return to top level. Hint 2: You do not have to launch from the top grating, anywhere along the side walkway is just as high.

My solution.

This map is AWESOME! Clean, simple design, but a really hard puzzle. I love it!

lmao that alternative solution was something i was trying to do early on in the puzzle then i figured, im sure this wasnt the intended way... so i went on solving it the intended way

this was a great map took me a while. i have to agree with the others about the panels. what if you made the panels smaller so that you could only have a spot for one portal?

Just a tip for this technique, don't place any portals in the middle of the panel. The portals lock on to the left and right side.

p0rtalmaster, an angular fling isn't necessary to solve this puzzle in the intended way (i.e., not using SAmAS's solution).

I really liked this map, and enjoyed the others you made for this series. It was a bit frustrating though when you do the fling over the water and the portal would appear left or right of where you were placing it, forcing you to start the entire sequence from the beginning (execution problems as stated in previous comments.) For anybody else experiencing this problem however, I found that if you wait to the very last moment before you shoot to create your portal, that it solves the problem.

I think that this chamber has a pattern which becomes a deadlock.

There's a common theme throughout the "no elements" chambers, and thus the difficulty can't really get harder than medium (unless of course some crazy ninja/speedrunning skills are involved).

Interestingly, anytime you have to fling angularly, such as using the extended arc flinging technique , it can cause some execution problems. Conceptually, however, it remains relatively easy.

Enjoyable. I agree with intermediate difficulty for this map. I had no execution problems.

Finally solved this the correct way. Execution was surprisingly difficult, couldn't get the portal placed where I was going to land. Had to use quick load about 20 times. Still, a clever map.

I finished this the same way as SAmAS, couldn't figure out other solution. Maybe will try another day.

It's hqrd to explqin it with words, but'll try. I got to the grated platform, made 2 portals on the floor. I jumped and, when Igot out of one portal I try to place a portal on that roof white panel in the other side of the goo. If I manage to plce it I land on the grated area and that's it. With those 2 portals placed the rest of the steps to reach the exit door are straight forward. I guess it's not a very elegant solution, but it's possible =p []

Yeah this map is one of my worse ones, how did you skip it might I ask?

Hey, I also completely ignored the right part of the map, yhought it was some kind of red herring but great map nonetheless. Grats []

I will seamlessly leave a map of my own here for you to test, it has a "no elemenrs" kind of room there. Each chamber is based on a deadly sin. Se7en Sins

Brilliant. I'm in trouble if this is 'intermediate', I spent ages trying to work it out on paper. In the end it's a lot easier to just work it out on the fly.

great shit

Definately didn't go for the intended way, completely ignored the right part of it... . Will sleep a night over it and try more.
