You may have already played the "Games for Engineers" that Zachtronics Industries is known for (Bureau of Steam Engineering, Codex of Alchemical Engineering). Now the author has come up with something new, and given its central concept you'd think playing it would blow up the space-time continuum. It's a computer game about programming computer chips. Welcome to KOHCTPYKTOP: Engineer of the People.

This game's a bit less accessible to non-engineers than the others were, but once you know what it's about, it's a cool puzzle game. You've just been hired to a semiconductor factory called H3, and your job is to construct computer chips that follow specific input/output rules. For example, on the first level you have to make four NOT gates (which outputs high current if supplied with low current, and vice-versa).

To build your wiring, click on one of the five commands on the right (or press the corresponding number key) to select it, then use the mouse to place what you selected on the grid. Click and drag to place silicon on the "lower layer" or metal on the "upper layer". Current cannot pass between silicon and metal unless connected with a VIA. Hold [Shift] to switch between the two types of silicon, or to allow the eraser tool to erase metal.

Only metal can connect to the twelve input/output squares on the border, and the "+VCC" squares are always supplying power. Once you think you've got things sorted out, click the Verification tab on the display at the bottom to test and see if your design works. If it does, great, move on to the next level; if it doesn't, go back and make some corrections.

The key to designing successful circuits is understanding how NPN and PNP gates work. Here's a quick lesson for the uninformed: NPN gates allow current to flow through the N-silicon "line" if current is supplied to the P-silicon "latch", and block it otherwise. PNP gates are just the opposite: current can only flow through the P-silicon "line" if there is no current to the N-silicon "latch".

If you're still confused, there's a tutorial video in-game that can help you understand things. We highly recommend viewing this before playing if you have any doubts at all. There are also some links to Wikipedia entries on the game's home page at Zachtronics Industries that explain certain concepts important for the higher levels, such as the Adder, the Flip-Flop, the Counter, and the Multiplexer.

Analysis: Kochy- Coch- Kochpti- aw, hell, Engineer of the People is one of the more difficult and engineer-oriented "Games for Engineers". Zachtronics is definitely becoming truer to its mission, although whether or not that's a good thing depends on the perspective of the individual. Let me just say that designing the screenshot level above wasn't that different a challenge from trying to solve some of the normal levels. It was fun, though.

I can't find much to complain about. The soundless audio and simplistic graphics we saw and loved in Zachtronics' past two games shows up again here, and the gameplay is well implemented. There's even a vague storyline hidden in the game.

Psychotronic - Though Engineer of the People once again provides an incredibly stimulating sandbox for ideas that other games dare not touch, I feel like it doesn't reach out to the user as much as it could. A more hands-on tutorial would help, and the editing tools could be more intuitive. I can select a section of circuitry and save it for later, but I would appreciate being able to rotate or flip it as well. I also found the working grid to be too tight, so that I often went outside of the lines and then had to go back and erase errant materials.

On the flip side, any game that has me involuntarily designing circuits in my head while I take a shower is doing something right. It's easy to share solutions, thanks to a simple copy-paste system like the one in Codex of Alchemical Engineering. Even if the concept sounds intimidating, give Engineer of the People a chance.

[Thanks so much for your help, but please use spoiler tags next time :D. ~Kero]

Even more confusing then the previous one... WOW

Still trying to figure this one out!

Great game.. I've been working my way trough 12 levels. It's just a maze of logic that you have to solve. (Tip: reading wikipedia helps)

I'm currently stuck on the multiplexor. I use a two to four gate and AND them to A,B,C or D. Problem is I'm getting too much noise - any way to cancel it?

March 26, 2009 7:43 PM

Kohctpyktop actually means "Constructor" in russian.

hm, really intriguing but I am finding it slow going since my backround in logic circuits is pretty much non-existent... Even with the "tutorial" it's obvious the creators didn't really care about making this accessible to people without a background in computer engineering.

I know the cyrillic alphabet though, and just a note that phonetically the name is konstrooktor = constructor! I don't speak russian, maybe that's the actual word in russian? anyway it's definitely not koch-pick-top ;)

March 26, 2009 8:19 PM

Great game! This is pretty similar to what I do for a living though...

Anybody have any idea for 1% on what you're suppose to do? I have exactly NO IDEAS, I only know that this game is impossible!

Despite seevral semesters of electronics engineering several years ago, I found the first level hard going. I suck :(

metastable, so is actual engineering work anything like this? I'd be curious to know because I'm contemplating trying to get into engineering but I have zero exposure.

hah, perhaps this is the wave of the future? Learn everything from music to engineering through video games...

I was so proud when I made it up to level 4... where I am totally stumped. can anybody who knows the concept give me a hint? like, is the idea to have a delay through a feedback loop, or what?

Great game concept, I'm really enjoying this so far! The UI, on the other hand, could use some work and additional functionality. Here's my list of problems that could be addressed in order to make this a more accessible game:

Problem one: no undo-function! I mean, come one. What we're doing here is basically drawing pixel art with the mouse or trackpad, and every so often I find myself messing up that straight line of metal or silicon I wanted to put down. Going back a step would be so much more convenient than having to painstakingly select the correct removal tool(s), and hunting down every wrong pixel.

Problem two: there's no way to remove vias without deleting the silicon. Why not remove them upon a second click with the "add via" tool?

Problem three: Exclusively using the Shift-key for switching silicon types - why isn't there a way to select between N and P with the mouse? All I want is to lean back in my chair, hand on the mouse, and think about the puzzle. And yet I need to have both hands up on the desk, one on the keyboard. To re-iterate: all 4 "pixel-types" necessary to solve the puzzle have to be selected from a icon tab by mouse, EXCEPT the 5th type, which has to be selected by holding down a key. Why not make the silicon icon change its color by clicking it again, or have two icons to begin with? Maybe it's just me, but Flash puzzles not based on movement, typing and/or reaction time should avoid using both the mouse and keyboard at the same time, at least for their most basic operations.

Problem four: despite looking for it a couple of moments, I honestly could not figure out if, upon solving a "level", there is any way to proceed to the next one other than going the "Quit to Main Menu"-route, "Oh my! You're going to lose all you data!"-warning and all.

March 26, 2009 11:23 PM

I'd be more interested in trying to learn and play the game if using the mouse to put down/remove material didn't alternate between non-responsive and oversensitive. Is anyone else having this problem? It seems like I have to run the mouse back and forth a lot quickly to get any silicon put down and then it automatically lays down stuff when I click elsewhere on accident???

YES! Got level 4 in what I'm sure is an atrociously inefficient way. But, I got it!

So I'm on #3 and got my X working fine, but my Y signal is inverted and I dunno how to fix it...any ideas?

hmm I had some extraneous bits I cut out for level 4. Note to my fellow amateurs; in this solution I've got a delay loop that could probably be used to solve the next puzzle (with the oscillators) with brute force. But I'm sure there's a better way, I'll try to find that. Any hints/tips for a better solution to 4 would be much appreciated...

I based it on m3psi's solution for level 4, with some tweaking to make an alternator.

March 27, 2009 2:59 AM

m3psi: It really depends on the type of engineering you want to get into. At a very simplified and fundamental level, this game gives a good feel of what design and layout is like (look up VLSI). However, most design is currently done with a pull-up structure(using PMOS transistors) and pull-down structure(NMOS), unlike this game.

KOHCTPYKTOP is impossible to pronounce because it's a joke involving the Russian alphabet.
Remember the backwards-Rs in movies like Red Dawn? Or how the Soviet hockey jerseys all said "CCCP"?

Each letter in KOHCTPYKTOP looks like a Russian character, though many make different sounds entirely, i.e. "H" is how the "n" sound appears in print. So, pronounced phonetically the title of the game is "Constrictor," though I'm not sure if the word means anything in Russian.

I need to learn to scroll up.

Being an electrical engineer, I really like this game :) To answer a question some post above: Actual engineering is a bit harder :) It's a crude simplification of what chip-design is about. Even the most basic gate (not-gate) has about 10 components of which the size plays an important part in the characteristics of the gate and need to be calculated.
https://jayisgames.com/images/hs_pam_engineerofthepeople_invlayout.jpg

But still, the game gives a bit of a feeling of what (digital) chip-design is about :)

On level 3 my Y solution "contaminate" my X, how can i prevent on side to corrupt another?

March 27, 2009 9:45 AM

Sylario: Use a separate voltage source for x and for y.

If you are not in chip design this is not how beeing an electronic is alike. If you work at basic level you don't do n and p layers. But get the and/or/not components ready made. Actually it were nand/nor/not don't know how it is today, since I'm at least 10 years of the show.

If you are producing 1000 units or less, you likely won't do any of that at all, and use a embedded cpu or an FPGA depending on the case... basic ones are cheap enough already, so you need quite a hugh quantity of of units to have a positive yield of the saved costs due to the increased development time.

On FPGA level, you basically just enter the circuit design, run compile, program the chip and plug it into your circuit...

As an engineer myself...I'm quite embarrassed to admit I have no idea how to implement a delay in this game ^^;; Can someone toss me a hint? Thanks :)

March 27, 2009 12:05 PM

If the delay is small, try making a snake with a wire....

If its quite large, well actually this is a very challenging task to do, pretty nontrivial.

#pinky_popo:

Hmm, didn't we have to invert signals somewhere on level 1? :)

fuzzyface:

Note that you can transfer copy and pasted designs between levels. So e.g. if you make a great (and compact!) AND gate, you can just copy and paste that in for subsequent levels. This is especially important for later levels, where you want to put together lots of parts from previous levels.

For delays, note that

Gates take time to operate. So create a path with lots of gates in it.

But anyways, great game - really fun reinventing important circuits from scratch. Though probably too hard for a casual game.

I can't get past level 6, though. I could do a selector + latch assembly, but the selector springs before the input switches off. I could do a delay, but, hmm...

Er, actually level 7 is the one I'm stuck on.

My solution for 7:

I'm quite proud of my level 3 (4 AND/4 OR) layout... I went for the most compact possible (now to optimise the score).

As an chip designer, I really like this game. :-)

This reminds me of the VLSI design classes I had back in grad school. Once I got over my preconceived notions of what should and shouldn't be possible ("Hey, transistors shouldn't be able to do that!"), then things got a lot more fun.

(Up to level 7 so far...)

I beleive that, with the red and yellow hammer and sickle indicative of Soviet Russia, this game's name is written in Cyrillic which would be transliterated into the Latin alphabet "Constuctor." I see it's been posted that it is constictor, but i dont beleive that to be the case. I just think it might be worth putting in the article as to avoid confusion. It's also easier to remember.

According to Google Translate, КОНСТРУКТОР (or конструктор in lower case) is indeed Russian for "constructor".

HELP! Getting weird delays on level 2. Created a fine OR gate, plugged in NOTted inputs and then NOTted that. According to logic this should be great. However, it's all messed up for me- there's a strange delay! Please help me! Is there a better or more compact AND gate? Code follows.

The VCC+ pad does not always supply current, at least when I played it. I was trying to make a simple solution to level 3 based on the assumption that the VCC+ pin would be connected, and it wasn't. Is this a random bug? Or are some levels meant to have you build without stable current source? ( not to get into the way none of these would even start to work IRL without a ground)

Help?

Wow, this game is awesome.

I only wish the game had a slightly better UI - Undo and Reflect X/Y options would have been awesome.

Hi again!
I have a problem with the S-R latch (double)- I get weird oscillation for 2 ticks, then my highs are delayed by a tick, and my lows are delayed by a half a tick. I am using a crossed-NOR latch as seen on Wikipedia. Code follows.

I found that writing out the whole thing in terms of boolean logic helped, as did having a set of the following simple snippets:
AND, OR, NOT, PNP, NPN,
that even if they were unable to be used directly clould even so be emulated and modified. Also, BE VERY CAREFUL! one missed via could throw the entire circuit off. If someone wants, I will post my codes for those snippets.

Woo! Fairly compact solution for level 10; just a half-adder and a full-adder in cascaded carry formation. 99%, design score 281:

Hi JIG!
Having some trouble with 11- getting weird spikes and delays- using design off wikipedia. those weird huge things in the middle (3 of them) are XOR gates I designed with 2 ANDs, a NOT, and an OR. Code follows.

The problem for me is that when something goes wrong, I can't tell why it's gone wrong. Can anyone tell me what's wrong with my design for Level 3?

@ N@: When you connect two lines together, a low line will be pulled high when the other line goes high. This is the case with your 'OR' gate: You connect all the lines to the same gate, thus, when one of the inputs goes high, the rest is pulled high too, affecting your 'AND' gate. Try buffering you inputs first before connecting them together:

But how can i see the "design score" for it everyone is talking about?

@JiGuest: The "Design Score" is shown at the top of the verification window when you run your test.

The score for your level 5 is 192, which would put you at #11 on Kongregates web site. Pretty good! :-D

I took a course on this last quarter. Somehow, I got a B in the lab and an A in the lecture...

March 29, 2009 6:14 PM

Mouse: I'm assuming you meant level 10, not 11 (the 2-bit adder) - your circuit's more-or-less ok, there's just too much gate delay for the signal to reach the output in time.

Here's an efficient pattern for an XOR gate (4 junctions, only 1 gate-delay in the output):

I hooked up the leads to show how it's wired, you can watch the verification pattern to see it's working properly.

You could also take a look at my post just before yours for a fairly minimal solution to the level using that XOR block as a main ingredient. (The recipe was one half-adder and one full-adder circuit straight off wikipedia's page on Adders ;)

Thanks so much! I seem to be having lots of trouble with gate delay. ^^

I'm really proud of this level 5 solution:

I can make:
AND, OR, NOT, NAND, NOR, XOR, and XNOR gates and diodes , and capacitors(oscillators) all out of transistors.

I come in here to look for possible ideas to see what I am doing wrong, and whenever I try to look at the spoilers, all I see is just (seemingly) random numbers and letters. What code is this? How do I view these images?

Nevermind, I just realized, sorry folks :-)

LOL, I was highly amused by your misinterpretation of the Russian name of the game. Nothing in the game, or in the screenshot you provided, says "Kohctpyktop". That is gibberish you made up. :) What it really says is "Konstruktor", but written in Cyrillic letters. It is a completely normal Russian word and means "designer, constructor", but it can also mean "construction set" in the sense of a children's toy.

If your comment system supports Unicode, this is what the Russian word really looks like: "Конструктор".

Could someone troubleshoot this design for 14 (shift register)?

The design consists of 4 memory cells with on-off switches (basically the set-reset latch from before). The data stream controls two gates, which should direct a pulse from CLK to either turn the cell on or off. But it doesn't work right.

@RobertB: Usually, "sneak paths" like that mean that when you're shifting your data from D to Q0, you're not *preventing* it from being inadvertently shifted on to Q1/Q2/Q3 as well.

For an inefficient illustration, take a look at:

It consists of eight "cells". Counting from the left, the odd-numbered ones shift in data only when clock is low, and the even-numbered ones shift in data only when clock is high. As the clock toggles, you can watch the data bubble down the chain.

Granted, you won't get a good Design Score with this sort of "master-slave latch" design, but it illustrates the concept (and gets the job done).

Hey guys, I need your help on level 13 - I can't get it! I got the clear down, I can't get the increment!

Hi! Im only 14 years old and i have won the first 13 levels. Still stuck on level 14 with 96% though. I really like this game and when i play it my friends go like: "WHAAAT? THATS IMPOSSIBLE!!!!" LOL :) So i think i could call my self a genius at this game...

LOL i love this game and i am doing great. I got to level 14 after playing this game "Alot" but the fun fact is that none of my friends can understand how i do it ;D. Seriosly no cheating! (By the way will Jay review the new game you have to download on the webside?) But the point is that eventhough you are not that old and goes in about 6-7 grade you can still be a genius at this...

I happen to know the Cyrillic alphabet, and the name is konstooktor of constructor

I created a large but relatively simple adder. It's just a 4 to 16 multiplexer coupled to a reverse 16 to 3 multiplexer. Is there any design with lower latency?

It uses two flip flops one of which is initialized to on. I'm working on a flipflop which starts as such but am having limited success

I'd love to enjoy this, but when you can't even understand how the filled-in walkthrough examples work by taking them apart, it's time to dig out the big, giant, "IMPOSSIBLE" sticker and move on. Most of them even seem to violate the stated rules of the game, power flowing when and where it seems like it should not, & vice-versa.

Sorry, but you tried to hard with this one guys. At least I could kid myself with the Alchemical Engineering one that the concepts were understandable. This one just has way too basic of an interface for such complex problems. Too hard to be enjoyable.

July 21, 2010 1:26 PM

I managed the first five levels, but 6 has me stumped. The tutorial needs to give a better idea of basic constructs. Any help?

November 10, 2010 6:51 PM

for the uninformed and for the reviewer of this game, the title is Russian!

it's pronounced KON-strook-TOR

April 8, 2011 12:54 PM

I so wanna play this game! I love engineering stuff! Thing is, I'm a big dummy when it comes to engineering stuff that doesn't involve optics and lasers.

But I'm also a big dummy for games like Konstruktor. And I wanna play on to see what this game has to do with communism.

Off to Wikipedia! In the words of someone who only made it quarter of the way through his Russian for Beginners: Ya zhelayu ponimat'!

I recently rediscovered this game, and find that it's still as much fun as I remember.* I'm still finding room for further improvements in all my old solutions (and some of the high scores on Kongregate's listings are insane).

* Granted, I work in the semiconductor industry, so this is right up my proverbial alley.

Here is a better solution for level 11. Score of 124.

for anyone that want the level 7 resolution here I leave it:

Here's my solution to level 16 - 2 bit function unit

condensed version (design score 356)

expanded version (easier to see parts)

each half of the design is made up of two parts, one which calculates a set of functions from the inputs a and b, and the second which selectively passes those results to the output depending on the selected function.

I only use three functions (a and b) (a xor b) and (not a) .You can combine (and) and (xor) results to get (or)

All the above functions are calculated in the first section then the required results are passed in the second section. Latency is one tick uniformly.

--the (and) result is required for (and) and (or), (F00/01) and is passed through when F1 is low
--the (xor) result is required for (or) and (xor), (F01/10) and is passed through if either f0 or f1 are high but not both.
--the (not a) result is only required for (not a), (f11) and is passed through only if f0 and f1 are high

it's quite compact (design score 349)

My first try of 11, 100%, design score 123.
I could've made it smaller, it's just two T-flip flops one after the other, with a rising edge detector for the input and the first flip flop.
