Gah! I used to be the brilliant one at Verba Retorta University, but ever since that damned Professor Wordberg showed up, there's been nothing but trouble. And it's all his confounded machine's fault!

He's a fraud – he has to be – I just needed enough evidence to prove it. So, last night, I... Look, it's not important how I got in there, but purely by happenstance, I found myself in Wordberg's lab after everyone else had left (and, as a tenured professor, I can assure you, I have every right to be there). Anyway, with no one else around, I took the opportunity to gather the proof I needed. I grabbed four words I happened to have in my pocket, loaded them up and started up his alleged "word transformation engine"...

Here's the video footage I took of the process (sorry for the poor quality, my phone's a little dated):

The Rube Wordberg Machine
The words I put into the machine were smallscale, nosier, apron, and outputs.

Anyway, after a lot of show, the machine's output was unceremoniously dropped into the bin at the bottom. But this is where things went wrong, and where I'm hoping you can help... The most obvious problem is that the machine appears to have actually worked(!), but right now that's not my concern. The immediate issue is that there were already words in the bin at the bottom and I don't know which are mine and which were already there. To make matters worse, some of them have been broken in the fall, and again, I don't know if they're mine:

bin of words
The words in the bin appear to be jerseys, tangible, pulse, newsletter, inputs, antonym, unpins, mustard, afford, and factory.

Now, under no circumstances can Professor Wordberg know I was in here, so in order to hide the evidence, I need you to help me work out:

  1. Which words from the bin are the, now transformed, words that I loaded in?
  2. If either of the two broken words are not mine, what word can I put through the machine again to create an unbroken copy?

    $\begingroup$ Awesome animations. I have no idea about what the machine does, though. Maybe antonyms... Outputs----> inputs $\endgroup$ – jaydm26 May 30 '16 at 13:15

    $\begingroup$ I +1ed the question just for the effort put in the animations. Wonder if the machine animation means something; the red cross/peach machine seems to behave a bit different with "apron", but that's the only difference i was able to spot. $\endgroup$ – Guntram Blohm May 30 '16 at 13:20

    $\begingroup$ @Alconja Don't listen to those questioning voices, just keep making stuff like this! I'm offended on your behalf that this puzzle only has ~300 views right now while there are mediocre, low-effort riddles of the same age getting 2k views. The "You approach the door" was awesome as well; I had no idea how to solve it, but just discovering it was fun. Lovely work. $\endgroup$ – Dan Russell Jun 1 '16 at 2:00

    $\begingroup$ Thanks for the support @DanRussell. :) But you're absolutely right re: views (and I mean across the site, not for me personally), we definitely need to find better ways of promoting awesome, but under-viewed puzzles here. It's so easy to miss quality content if you don't log in every day. $\endgroup$ – Alconja Jun 1 '16 at 2:49

UPDATE: I wanted to confirm my suspicions, so I snuck into Wordberg's lab with a modified X-ray device, and I was able to verify via video that my descriptions below are indeed correct. I was only able to capture video of one of the words Alconja tried, but here it is:

enter image description here


Looks like this very cool machine has a bunch of components wonderfully hinted at in the illustration.

It seems that first the input word is

split into two parts with one part following the left path and one following the right path. There is some ambiguity in which half goes to which path.

The left path

is an antonym machine, represented by the full change in color from a dark red to a light red. The antonym is then stored at the bottom of the left path until the word on the right path is complete. When the final right-side product is ready, the left-side antonym is flipped and stamped in the middle.

The right path

has four components. The first component (light blue) rotates a single letter. The second component—the green box with pistons—picks up one letter and moves it elsewhere. The third component (red plus sign) increments the value of the first remaining letter by one. And the fourth component (the final blue-bracketed component before it drops the word into the bin) stretches the remaining letters out to allow the antonym stamping in the middle.

So the first pair of words is

smallscale and tangible

because

smallscale is split into "small" and "scale"
The "small" goes down the left path and is converted to "big".
The "scale" goes down the right path and the "c" is rotated 90° to become an "n", leaving "snale".
One letter of "snale" is moved to a new position, leaving "sanle".
The "s" is incremented to become "t", leaving "tanle".
"tanle" is stretched to "tan---le" and big is reverse-stamped into it to make tangible.

And the second pair is

nosier and jerseys

because

nosier is split into "no" and "sier"
The "no" goes down the left path and is converted to "yes".
The "sier" goes down the right path where the "s" is rotated 180°, leaving "sier".
The "s" from "sier" is moved to the end, leaving "iers".
The "i" is incremented to "j" leaving "jers". "jers" is stretched to "jer---s" and yes is reverse-stamped into it to make jerseys.

With the third pair being

apron and afford

because

apron is split into "apr" and "on"
The "on" goes down the left path and is converted to "off".
The "apr" goes down the right path and the "p" is rotated 180° to become a "d" leaving "adr".
One letter is moved from "adr" to give us "ard".
The incrementing component malfunctions and no letters are incremented! As Guntram Blohm pointed out, this can be seen in the animation during the "apron" sequence.
"ard" is stretched to "a---rd" and off is reverse-stamped into it to make afford.

And the fourth pair is

outputs and unpins

because

outputs is split into "out" and "puts"
The "out" goes down the left path and is converted to "in".
The "puts" goes down the right path and the "u" is rotated 180° to become an "n", leaving "pnts".
The "t" from "pnts" is moved leaving "tpns".
The "t" is incremented to become "u", giving us "upns".
"upns" is stretched to "u-p-ns" and in is reverse-stamped into the blank spaces to make unpins.

If all that's true, then the tile we need to replace is

inputs (since "tangible" is the other broken one and we generated that)

which we could do by entering

shutdown

because

"shutdown" will be split into "shut" and "down" The "down" goes down the left path and is converted to "up".
The "shut" goes down the right path and the "u" is rotated to become an "n", leaving "shnt".
The "s" from "shnt" is moved leaving "hnts".
The "h" is incremented to become "i", giving us "ints".
"ints" is stretched to "in--ts" and up is reverse-stamped into it to make inputs.

All this leads me to conclude that when Alconja gets around to making a word machine, it'll far outperform Professor Wordberg's and restore Alconja's place in the Verba Retorta hierarchy!

    $\begingroup$ "Why" nothing is incremented in the apron/afford case i don't know, but "that" nothing is incremented can be seen when the "+" machine briefly shows a bold red '+' with the other 3 words, but not with apron. Also, for some reason, all other words have the first half go down the left pipe; apron is the only exception where the second half goes left. $\endgroup$ – Guntram Blohm May 31 '16 at 6:54

    $\begingroup$ Looks good, well done (and you picked a perfect replacement word)! A couple of minor notes though... Pay close attention to the animations: All words get a single letter spun (so your "s" x180° theory is correct). The green shaker isn't strictly an anagram maker, it lifts a single letter moves it randomly around and shoves it back down wherever it stops. As @GuntramBlohm observes, the "+" component malfunctions on apron. The "in" in unpins does get reversed, just in this case the stretching/merging process causes an overlap (you just need your shuffle to start with u-p-ns). $\endgroup$ – Alconja May 31 '16 at 10:32

    $\begingroup$ @GuntramBlohm - As to why apron doesn't get incremented, the apron merge is imperfect, the split falls down different sides (note the extra word follows the same split pattern as apron)... Looks like the machine is at least somewhat nondeterministic, and I just got lucky. Maybe Wordberg is a fraud after all! ...also, from a puzzle making perspective, it was hard enough to find these words without making the transformation rules even more restrictive. :) $\endgroup$ – Alconja May 31 '16 at 10:41

    $\begingroup$ @GuntramBlohm Good catch! I hadn't seen that malfunction on apron. Makes sense now. $\endgroup$ – Dan Russell May 31 '16 at 11:10
