The Best of Demon Arisen (30+ Fun & Logical Puzzles)
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! :)

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...

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...

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...

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...

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.

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 is a complex yet fun logic puzzle for those who want a challenge.

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...

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!
