The idea is that you have to break into and exfiltrate data from a laboratory that uses their own transputer-like architecture. Write a mobile program to explore the network, another to start migrating the data, and so on. Migrate too hard and the humans notice and reboot the network, kicking you out. There could be other players in there too. Of course, the nodes run the lab's terrible version of Forth. There's no UI, you connect via a TCP socket, and are expected to write your own tooling.
I'm not sure if this is a good idea or if I'm having a psychotic break.

But apparently the Kaizen-making company is still Zach Barth?
So what was Zachtronics closing then? Him changing his mind and coming back a year later? Why throw away the brand? As cringingly shallow as that sentence was to type, a new "Zachtronics" game was a reflexive auto-buy for many people.
> Back in 2016, we sold Zachtronics to a company called Alliance, who we worked for as employees and made all the Zachtronics games from SHENZHEN I/O onward. In 2022 we stopped working for them and started a new studio called Coincidence, which we own and run as a sort of co-op that allows us to work on projects together, or not together, or anything in-between. (By "we" I mean the five of us who made all the Zachtronics games from SHENZHEN I/O onward; the team was much more dynamic before that, as described in the first few pages of ZACH-LIKE.)
> I still work for Alliance and maintain the Zachtronics games, but we don't own any of that IP, so anything new we make is going to be attached to the new studio and the new name.
(I did spend a year teaching computer science at a public high school, but that overlapped the last year of Zachtronics, rather than being between Zachtronics and Coincidence like it's often reported.)
At Coincidence, we have released two puzzle games so far, Kaizen: A Factory Story and U.V.S. Nirmana, and have more (four?) in the works. I'm hoping that I'll get to work on some less-obviously-in-the-genre games soon, but I haven't git initted anything yet so I guess it's too early to say.
From other comments in this thread, it seems I am not the only one who misinterpreted that as not including Zach himself
It's not clear that this happened here, but I could imagine that someone successful enough not to need the money might literally prefer to have their work evaluated on its own merits and not have the outsized level of attention that being well-known brings. I remember reading in Eric Clapton's autobiography (which might or might not be an accurate retelling of course) that the original plan for Derek and the Dominoes was to name them "Del and the Dominoes" and basically hide the fact that he was the guitarist since he was tired of all of the attention. According to him, "Derek" was a slip of the tongue from someone on stage one night, and the record label eventually decided to try to capitalize on his hype by marketing the fact that he was behind it.
Happy to hear that he's continuing developing games and we can expect more to come!

My biggest surprise from playing EXAPUNKS is how futile it is to try and pre-optimize a solution. I had to remind myself time and again to solve the puzzle first, then try and try and optimize it.
While the games are fun on their own, I recommend playing them at the same time as a friend. Trash-talking about finding more optimal solutions really added to the overall fun of playing the games.
They definitely straddle there line between "those is a fun video game" and "it looks too much like my job" for people in the industry, but there's a whole genre of workplace simulators for doing other people's jobs vicariously. A semi truck driver would see playing a semi truck simulator in the same way, but American Truck Simulator is quite popular. Anyway, play Zachatronics games if you find them fun, but if you don't, then, uh, don't feel bad about not playing them.

It seems like a missed opportunity not to name-drop 2600. But I guess they wouldn't be allowed to do that anyway.
Spacechem was my intro to Zachtronics, and it consumed me when it came out. The concept of instructions inside the actual work area is amazing and still makes my head spin. I consider beating Ω-Pseudoethyne one of my top coding/steam achievements.
I fell off for a bit because the leaderboard grind against friends felt draining, but rekindled my joy by mostly ignoring them (Unless I'm way out of distribution). I'm so glad Zach and the team are back.
All the joys of code reuse (as silly as that might sound) do get kinda lost in the game. I still loved it, but I'd kill for a sequel that was a little higher level on the tooling.
They’ve released two Zach-likes, Kaizen and UVS Nirmana.
Blatant self promotion, but if you want the full story, he chatted to me about it on Software Engineering Daily after the release of Kaizen: https://softwareengineeringdaily.com/2025/12/18/designing-in...
Exapunks can be pretty tricky with the distributed nature, which share some similarities with TIS-100. Like Opus Magnum, though, there are no restrictive code size limits, meaning that some puzzles can be solved with brute force masses of code. It's not as bad as Shenzhen I/O where you have to deal both with a tiny MCU and routing.
they are quite unique and very well-made though. if you like sequence-puzzle games but are getting tired of the endless flood of Sokoban-flavored things, give it a try!
1. It had the least overlap with my day-job work.
2. It's somehow more-pleasing to watch a mechanical (albeit simulated) 3D machine do work, contrasted to the flickering playgrounds of Exapunks or Shenzhen IO.
