Mikeastro's Logic Maps

Description
A collection of maps that involve pure logic reasoning.
They range from quite easy to actually rather difficult.
Mostly lasers and funnels; sometimes also light bridges.
I hope that anyone who happens to stumble upon this collection has fun solving them!

The puzzles are arranged more or less in ascending order of difficulty.
All are assigned a number on a scale from 1 to 10 to express the approximate difficulty numerically.
This rating is based on the average player; are you very experienced? It might be easier. You a beginner? It might be harder.
Roughly, 1 is trivial, 4 is solvable if you have a clear mind, 5 requires a clever idea, 7 is hard.
No 9s and 10s because if I can think it up, surely it can't be 'that' hard!
Expected solving time: (5/3)^{Difficulty} minutes - grab your nearest calculator and see for yourself!

Always remember:
A puzzle being hard, doesn't make it good.
A puzzle being easy, doesn't make it bad.

Relatively new to the Portal 2 workshop?
Consider playing these first: Reliquiae series.
An experienced player and feeling confident?
Consider playing these first: Best Of.
It's a Best Of collection, consisting of most of the more challenging maps, with the cleanest designs.

Suggestions, remarks or other things you would want to say?

Mini Mono

Homage to old me

An old friend of mine has repeatedly requested me to make an easy map, so here it is. Three rooms that become increasingly less trivial, but none of them are hard. Map features custom music as well, so yeah... cool stuff. Found an unintended solution? Plea...
Theorem
Created by Mikeastro
Okay so this is not an actual portal puzzle, even though it technically is a portal puzzle. It's just something I thought of today and I thought maybe a selected few of you would like it. Maybe that is not the case, but that doesn't really matter. Anyway, ...
NoLime
Created by Mikeastro
A tiny decent map that is nothing special. Just to keep my workshop a bit alive. This is a slightly polished version of my hidden map "Lime" that was broken but still won Nock's mapping competition. The idea was to make a puzzle in which no cube ever trave...
Hanoi
Created by Mikeastro
And there you have it - my first zero portals 'puzzle'. A map dedicated to my friend Joric. Back in February, he published a map which was a remake of the second room of this map. Using his words, possibly quoting yet someone else: ''Room 2 is one of the b...

Orientation

This is a tiny map based around an idea I had recently. I haven't really seen it anywhere else yet, but I'm sure someone has thought of it before at some point. I don't know whether or not I will ever implement this into a full puzzle, but for now, this is...

Worlds Apart

This is a concept that I've had in my head for quite a while at this point. DR's mapping contest gave me the perfect opportunity to work it out into a small map. It won't be a winner, but I like it anyway ^_^ Edit: it actually won o_O This is my third mono...

Manifold
Created by Mikeastro
A small map just to let you guys know that I'm still alive. This one should be pretty easy, but I kinda like it for some reason. It has cubes, pistons and flip panels... oh, and there's a laser too. Sidenote: I had this map effectively completed a month or...

No Elements: Coprime
Created by Mikeastro
For the first time I tried my hand at a No Elements type of test; I'm curious about what you think of it. I do think that some experience with this style of testing is required to make it out, though I'm not really sure about that. Special thanks to jgault...
No Elements: Coprime (Remake)
Created by Mikeastro
A remake of an old puzzle of mine, to support my latest video about "No Elements" puzzles. I hope it's not broken, but it might be - who knows? The solution does not require superhuman reflexes and if done correctly, it should be able to be pulled off with...

Excess Access
Created by Mikeastro
I got the idea while working on my last puzzle, and the thought was just plain awful. Therefore I decided to make this test and you will probably hate me for the rest of your life after solving it. Don't get the wrong idea though; no tight timing, tossing ...
Dual (Remake)

Homotopy

So it would seem that I have already become so arrogant that I cannot be satisfied with publishing an easy puzzle anymore. Who would have thought it would happen so fast? Therefore I bring you 5 puzzles in one map - none of them should be hard, but I hope ...
Think Ahead (Remake)
Created by Mikeastro
A remake of an old map of mine; Think Ahead. I boiled it down to the laser puzzle at its core. Difficulty: 3.5/10. What do you think? Should I keep the old map or just delete it? Edit: in the end, I decided to delete it. Big Update: My puzzle game Sokoban:...
Disaster
Created by Mikeastro
This map is just one big disaster, in every aspect. For once I really put effort into making the test look nice... oh man, the price I had to pay. I've seen glitches, bugs, errors and crashes - everything that could technically go wrong, went wrong. But at...
Circle
Created by Mikeastro
The horizontally moving platform is sadly one of the most underused test elements... This should be a pretty neat, small test making use of its unique properties! Difficulty: 4/10. Big Update: My puzzle game Sokoban: The RPG has been released on steam! Ple...
Sheaf
Created by Mikeastro
If you look up the word ''sheaf'' in the dictionary, you might find something like: ''A bundle of grain stalks laid lengthways and tied together after reaping.'' Allow me to tell you what a sheaf really is: Definition: Let X be a topological space (typical...
Isomorphism
Created by Mikeastro
So I had this set-up and I just compiled the map trying to see if I could make it to the exit. For some reason it took me well over half an hour to figure out the last step, but in the end it's really not that hard to spot. Though altogether I thought I ha...
Morphism
Created by Mikeastro
When I started making this map I was totally and utterly uninspired. Now that I'm done, the whole thing suddenly feels very inspired and I think I got really lucky it all clicked so nicely so quickly. Just another one of those small laser puzzles that are ...
Twist

This may look like an ordinary test chamber, but there is a twist... Difficulty: 4/10. Big Update: My puzzle game Sokoban: The RPG has been released on steam! Please consider checking it out!...
The number 4
Created by Mikeastro
Hello, it's me again. The guy with the comically bad thumbnails. I have returned with a map that is centered around the number 4. I was going to release it on April Fools, but since that concept is kinda lame and overdone at this point, I decided to releas...
Split (Remake)
Created by Mikeastro
It's been years since I last remade one of my older puzzles, but Split really deserved it. To celebrate the occasion of my turning a quarter of a century old, I bring you this map. It effectively has only a single connection, no fizzlers, one funnel and on...
Eight
Created by Mikeastro
Today I present two test chambers and one essay. Feel free to disregard the latter. Two times four sectors makes eight in total - the rooms may seem similar, but their solutions are very different. Music is not custom as the design reminded me of my own Sq...
Inertial

Block Logic
Created by Mikeastro
This is my entry for Dark Rozen's third mapping contest, which required the mapper to introduce a concept of bootstrapping and it had to include turrets of some kind. This is the sole reason for the turrets near the exit; it's a bit of a cheap usage, but i...
Bottom Line
Created by Mikeastro
Truthfully, I kind of really do not have the time to make these maps this semester. And I really considered simply uploading the first room just so that you wouldn't forget about me... Naw I'm being dramatic - it goes without saying that, in the end, I did...
Split
Created by Mikeastro
It would seem like the funnel should have to have both polarities simultaneously... Can you work around that? Difficulty: 5/10. Big Update: My puzzle game Sokoban: The RPG has been released on steam! Please consider checking it out! Playthrough by leomievs...
Talos (iii)
Created by Mikeastro

Module
Created by Mikeastro
Can we get some hype in the chat? New puzzle, but I don't really want to give away too much this time. Pretty small map, but it should be a little tricky. No tight timing, bunny hopping or other execution difficulty involved, as usual. Anything that seems ...

Commute
Created by Mikeastro
Just some little ideas with the sendificator. This puzzle has been in the works for quite a while. As can be seen from the thumbnail, one of the fizzlers uses an OR gate. This sendificator is a little special: cubes can only be placed on it in a fixed orie...

Square Puzzle
Created by Mikeastro
This might be one of my best puzzles yet. Difficulty: 6/10. PS. If you still manage to pull off the door glitch - no, that is not intended. Solving it for realsies is much more fun. Same goes for cube tossing, strafe jumping etc. Big Update: My puzzle game...
Canonical
Created by Mikeastro
This map features custom music that I composed myself. Since this was more of a test run to see if I could get it to work (and I think it works now!), it might not be very ''portal music like'' yet, but I hope it is not too annoying to put up with while so...
Cocycle
Created by Mikeastro

Point Symmetry
Created by Mikeastro
Allow me to walk you through my day today. Bored as I was, I made a 3x3 grid in the editor and filled it with fizzlers and receivers, two lasers and two cubes. I didn't yet know what the exit requirement would become, but I fooled around a bit and started ...
Modular Form
Created by Mikeastro
It has been quite some time since my last major release. This is not a puzzle to illustrate a concept, nor is it tied to any of my videos in any way. This puzzle stands firmly on its own. Here you will find precisely 7 portal surfaces and only 2 short antl...
Peculiar
Created by Mikeastro
It took quite some hours to get everything set up perfectly for this challenging logic map. And to think that there are only 7 portalable surfaces! Difficulty: 6.5/10. Note: holding the cube under the track plaform is a known exploit - try not to do that w...
Neurons
Created by Mikeastro
This one is not for the fainthearted. You will need nothing but pure logic for this challenging map! Difficulty: 6.5/10. Playing through most of the maps in Enigmatic's amazing series of test chambers Neurones en Reflexion, I was filled with inspiration. T...
Reflection

Two cubes, one laser, few portals, many steps... Difficulty: 6.5/10. I hope you enjoy it! This map was directly inspired by Enigmatic's Neurones en Reflexion 22; coming from an amazing series of testchambers I would recommend anyone to check out. I felt li...
Inverse
Created by Mikeastro
Large and complex puzzle, focussing on a single invertible funnel. Very long antlines ahead - they don't cross, though. One side of the room sort of controls the other, and vice versa. This should be quite tough, please let me know your solutions :) I hope...
Localisation
Created by Mikeastro
So here we are again - for the past two weeks, this map has been my life outside of uni, basically. For a while now I've wanted to make a proper hard puzzle again, and well, here it is. Twice earlier in the design process I was ready to publish the map, on...
Vector
Created by Mikeastro
More custom music - yay! Fun story: this began as a cute little puzzle, but then I wanted the player to bring both cubes up. Suffice it to say it grew far too complicated and I think that I managed to force a quite subtle solution. If my solution is the on...
The Machine Room

The Serpent's Pass
Created by Mikeastro
It has been way too long since I published a challenging fizzler evading grid-based pure laser puzzle. There's only 8 fizzlers and a like number of receivers; how hard can it be? I hope that you guys will enjoy this one. And I hope it isn't broken. If ever...
Indecision
Created by Mikeastro
Hello and welcome and I'm sorry. This map is here to test your pure, abstract laser puzzle skills - yes, another one of those by my hand. I wanted to remake my old and fairly mediocre Emancipation Separation, so I did. The result is the first room... and t...
