This is it. My 40th test chamber. And it's one of my best yet.

This challenging brain-teaser is almost certainly my hardest one ever: you'll have to use all the wit and intelligence you can muster in order to complete it.

Estimated difficulty: Advanced

...
Switch
Created by Demon Arisen
Switch seamlessly between a light bridge and a funnel with just the flick of a switch. Well... With the deactivation of a laser node. But that doesn't sound as catchy.

So yeah, this one isn't too hard. But it uses an interesting mechanic and I hope it's...
Sequential
Created by Demon Arisen
EDIT 1: Refined the test by removing angled panel and portalable floor, checked for exploits and trapping issues.

EDIT 2: Removed some portalable surfaces to prevent exploits

Order is everything. Only by placing the right portals in the right places ...
Suction
Created by Demon Arisen
I wanted to make something involving a reversed funnel, so here we are!

Difficulty: Easy - Medium

Check out my workshop for more logical and fun test chambers!

Comments and criticism are welcome. :)...
Indirect
Created by Demon Arisen
Simply complicated. The easy way out doesn't always work.

Cave Johnson here.

Lab boys tell me most of you were unable to solve this test and you're stuck in there with nothing but mantis-men corpses to keep you company, and now you're groaning that ...
Reset
Created by Demon Arisen
An intermediate difficulty puzzle, Reset involves only buttons, fizzlers, and a cube - but while the test elements are simple, the puzzle itself is not....
Pure Logic
Created by Demon Arisen
Logic and Lasers and Light Bridges make up this brain-bending puzzle. It looks simple, but appearances can be deceptive.

Comments and criticism are welcome. :)...
Dynamo
Created by Demon Arisen
Finally! A new chamber! It's been a while, hasn't it?

Combine a light bridge and an excursion funnel with repulsion gel to defeat the turrets and reach the exit in this mind-boggling intermediate difficulty puzzle.

Comments and criticism would be greatl...
Pure Logic Less Logical
Created by Hazellius
A small change to the original map by Demon Arisen. Never seen this little concept used in a map as the intended solution and I like it.

Be sure to check out the original map:

Simplicity
Created by Demon Arisen
Not my best, to be honest, but hopefully it's still fun, and I think the solution is a little bit clever. :)...
Levels
Created by Demon Arisen
Of course I won't provide a description for my creation, what are you talking about?

I noticed I haven't done much with separate heights and levels, so I created this logic puzzle as a little experiment. Have fun!

Difficulty: Intermediate

Minor ti...
So close.....
Created by Demon Arisen
.....and yet so far.

The exit is right in front of you, but you may need just that little extra blob of gel to reach it. It's bouncy puzzle-solving fun for the whole family! Okay, maybe not the whole family.

Difficulty - Medium.

Precision
Created by Demon Arisen
The sequel to my highly-praised* chamber Indirect. Just direct the laser into the catcher and walk to the exit. Simple.... Right?

If you are stuck try Indirect first, it teaches lots of the concepts displayed here.

Difficulty: Easy/Medium (Depends u...
Excursion Conundrum
Created by Demon Arisen
This was going to be a Hammer map with custom visuals, music, dialogue, secrets, surprises, and awesomeness. But it isn't, because Hammer is the most buggy, unintuitive, confusing, overcomplicated program I have ever used... It's very powerful but I just d...
Indirect Redux
Created by Demon Arisen
A remake of one of my best chambers (Indirect), Indirect Redux is a head-scratching puzzle which looks extremely simple - but it isn't.

So what's changed from the original?

It's better looking, gameplay flows better, the puzzle has been tweaked and refin...
Just a little one...
Created by Demon Arisen
Just a little chamber, because a little chamber is better than no chamber at all.

Not my best I know, but I'm out of ideas.... :(

This is a remake of Demon Arisen's map Levels. I'm not too happy about this one, but it'll have to do....
The Pulse Experiment
Created by Demon Arisen
Cave Johnson here. We just finished perfecting the new Aperture Science Oscillating Pulse Drive - catchy, right? It allows stuff to switch on and off on an automatic timer.

Anyway, soon we're going to use this new technology to create a new type of str...
Pressure
Created by Demon Arisen
EDIT 1: Completely removed the two normal cubes, the flip panel, and the button which activates it, since none of them were required to solve the test (whoops) . Also made lots of visual tweaks.

Difficulty: Medium



...
(3x3x3) Nudge.
Created by Demon Arisen
Just a tiny test because I had this idea to do with using a light bridge in a clever way. A proper chamber should be out soon, but you can play this in the meantime. Aren't you lucky? Yes you are.

Estimated playtime: <5 mins, probably.

Difficulty: In...
(3x3x3) Direction
Created by Demon Arisen
EDIT 1: Neither the cube nor the player should be able to become trapped. Moved the laserfield and added a respawn button for the cube.

A slightly trickier and more complex 3x3x3 room than my last one, again using a slightly odd technique possibly unknown...
Access Denied
Created by Demon Arisen
This may just be one of my best tests yet.

To mark my 30th chamber (woo!) I made this test which I had a lot of fun doing and which I reckon might be one of my best.

The solution is hidden in plain sight in this simple-looking chamber which is far from s...
A Light Challenge
Created by Demon Arisen
EDIT 2: Extended the grating to prevent exploits.

EDIT 1: Made objectives clearer, for example the exit is now directly in the players vision as they enter the chamber. Added grating and removed part of a portalable surface to prevent unintended solutions...
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...
Pons Lucis
Created by Demon Arisen
Utilise a light bridge and a funnel to reach the exit. The catch? You only have access to one of those two at a time.

Difficulty: Intermediate

I'm busy for the next couple of weeks or so, but I promise I'll have a chember up when I have some free time (...
Eradicate
Created by Demon Arisen
A short-but-sweet chamber which focuses on a cool move.

Flatline (1-Wide)
Created by Demon Arisen
This is a puzzle made especially for RageGamingVideos, but other people can play it too. :-)

My aforementioned 40th chamber is coming soon! :-D...
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...
Stationary
Created by Demon Arisen
An easy little conversion gel test with a twist - the player cannot move off the platform he starts on.

This test focuses on being fun and satisfying to solve, and isn't quite as much of a challenge as my usual things.

So this is quite different to my no...
Fluid
Created by Demon Arisen
An elegantly challenging logic puzzle based on mobility gels.

This chamber took me a long (and I mean really long) time to get absolutely right, so I hope you like it! :3

Linked
Created by Demon Arisen
I had a thought the other day. "Hmm. Most gel puzzles are huge and expansive. I'm going to make a really small and compact one!" Thus "Linked" was born.

On an unrelated note, this chamber might win the award for Most Glass and Grating Used in a Test Ch...
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 ...
Accelerate

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...
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!

:-D...
