Description
A collection of my very best fun and logical test chambers, in order from easiest to hardest. Bear in mind that "best" doesn't necessarily mean "really difficult" - in fact, the first few are quite easy to gradually get you used to my way of thinking - but I am proud that I designed every single one, and all of them received hundreds, if not thousands of players, and overwhelmingly positive feedback.

If you want to learn how to make tests like these, check out my Youtube channel

Enjoy! :)

Return
Created by Demon Arisen
You must return to places you have already looked in this fun, medium difficulty logic puzzle.

But that is not the only reason I named this chamber "Return". This is the first chamber I have made since November, and so this marks the return of Demon Arise...
Refraction
Created by Demon Arisen
I'm back! I'm not dead! Yay! Welcome to Refraction,
my first test of 2016. I know, it's May, sorry, I've been really busy getting ready to go to university, preparing for exams etc.

So what did I miss while I was gone? WOW, over 100 followers!? That's a...
Sunscreen

Cave Johnson here, reminding all test subjects to apply a generous coating of Aperture brand sunscreen all over your body before entering any test involving a Hard Light Bridge. And I mean all over your body. Eyes. Hair. Teeth. Yes, even your... gentleman'...
Divided v2.0
Created by Demon Arisen
Cave here. Huge, dark, and smelly cave. What? No, I'm not talking about myself! I am literally inside a cave right now and I have no idea how to get out. Seeing how I don't exactly have many creature comforts in here, I'll probably be rat food very soon. C...
Catharsis
Created by Demon Arisen
Cave here. According to those uptight snobs in the PR department, my pre-recorded messages have been getting a little too... inappropriate lately. Apparently test subjects have been seen sat in the corner sucking their thumbs at the mere mention of that ac...
Fuse
Created by Demon Arisen
Use a light bridge and a laser to complete this deviously compact test chamber.

UPDATE: Thanks to RectorRocks for the new title <3...
Elide
Created by Demon Arisen
Easy-ish difficulty laser puzzle. Have fun! :)

If you are stuck and need a hint: Look up the definition of the word "elide". Also, Demon Arisen veterans may recognise the solution from two previous puzzles I've made.

EDIT 1: Fixe...

Dual Inverse Helicoidal Infundibuliforms

Medium difficulty Excursion Funnel puzzle.

(Title translation: Two Opposing Helix-shaped Funnels) :P

I'm really proud of this one. It's not my hardest but I think it's a pretty fun puzzle with very clean design. Hope you enjoy playing it as much as I enj...

Stranger than Friction
Created by Demon Arisen
EDIT 1: Exploits people have pointed out (thanks, people) should now be fixed. However, some people have told me they've found four solutions or whatever, but then haven't told me what these solutions are! I can't fix unintended solutions without knowing w...

Toxic

Hello, Test Subject, it's Cave. You may have heard that we recently acquired a little extra budget after yours truly fired that idiot Jeff from the engineering department. So, as a celebration of Jeff not being able to provide for his family anymore, we th...
Cyan and Vermillion
Created by Demon Arisen
Cave Johnson here. For this next test, we've put deadly nanomachines in the oxygen supply. If you feel your lungs being agonisingly ripped apart by nanoscopic robots, that's normal. Just take a deep breath, and... Actually no, that'll make the whole thing ...
Fluid (V2.0)
Created by Demon Arisen
Cave here. Now, I know you're here to solve brand new tests but our design team went on strike the other day due to "unsanitary working conditions" just because there's a little radioactive fluid here or there... or everywhere. So since they're off protest...
Accelerate
Created by Demon Arisen
Accelerate is a complex yet fun logic puzzle for those who want a challenge.

A much larger and more complicated chamber than my usual tests, this medium-hard difficulty logic puzzle focuses on fun mechanics such as repulsion gel, flinging, turrets, and ex...
Amber
Created by Demon Arisen
Cave here. Apparently one of our employees was out "walking the dog" the other day - at least that's what he told me - when their dog just happened to dig up a lump of fossilised amber. Now, if you ask me it sounds like he was doing an archaeological dig w...
Paradox

"Good morning, employees! Cave here. Welcome to yet another Fairly Advanced Robotics Training Seminar, or FARTS for short. Yeah yeah, I know, get your laughs out now. I don’t make the acronyms around here. But I do the FARTS! So, without further ado, it’s ...

Skybox
Created by Demon Arisen
One of the best puzzles I've made recently, Skybox is a medium-ish difficulty faith plate and funnel puzzle, where which portal goes where is key to reaching the exit door in the box in the sky.

Hope you all enjoy it!

Access Denied (v2.0)
Created by Demon Arisen
Cave Johnson here. Just a reminder that I'm your boss and I have the power to fire your butt whenever I please. And by your butt I mean you, because to be honest I can't even tell much of a difference right now. That's right, I am NOT happy. Some wise guy ...
Axiom
Created by Demon Arisen
Cave Johnson here. I've just been informed that a Mr L.B. from our programming department has been unwell recently. Sorry about that, it's probably the micro-parasites we put into your keyboard. Don't worry about it, all they do is make you feel unwell but...

Hello Test Subject, it's Cave. Not gonna lie to you, this test is pretty difficult compared to this moron's usual chambers so you'll probably be in here a little while. So, if you need to go to the bathroom, just find a quiet little corner and keep it neat...
