A build is one published version of the game's files on a branch. Steam assigns a new build ID every time the developer pushes an update, so this list is the update history of the app. The files inside a build (depot manifests) are only readable with an account that owns the game, which SteamRaw does not have yet, so build contents are not shown.

Turbo Golf Racing and Shenzhen I/O are now on Game Pass
2022-08-04 15:45 UTC · Rock, Paper, Shotgun
Two more games hit Game Pass today, one oldie-but-goodie and one newie. The oldie is Shenzhen I/O, an excellent Zachtronics puzzle game from 2016 where you design circuits and program hardware. The newie is Turbo Golf Racing, which looks like Rocket League for minigolf and is hitting Game Pass on the very day it launches. Shenzhen is absolutely worth a go if you enjoy Zachlike puzzlers, and Turbo Golf looks like one of those "could be fun, sure I'll give it a try" Game Pass games. Read more

Zachtronics games now free for schools
2019-07-04 10:48 UTC · Rock, Paper, Shotgun · contact@rockpapershotgun.com (Matt Cox)
Cor, kids have it easy nowadays. Sure, they’re inheriting a polluted hellhole teetering on the brink of ecological and economic ruin, but look at all the neat games they get to grow up with. Thanks to Zachtronics announcing they’re giving away (nearly) all their games to schools, some of them even get to muck about with fabulously inventive puzzle boxes during their pretend workday. Imagine that! Privileged tykes. (more…)
Zach-Like comes to Steam free with loads of game-like extras
2019-06-18 18:39 UTC · Rock, Paper, Shotgun · contact@rockpapershotgun.com (Dominic Tarason)
Zach-like, the book about Zachlikes by Zach Barth, creator of the genre, is now free albeit notably less papery now. Zachtronics’s previously Kickstarter-exclusive book was a collection of design documents from the creator of Spacechem, Opus Magnum, Infinifactory and many more, showing just how he engineers his puzzles. Now anyone can read a digital version for free, and it comes bundled with a pile of his early browser games, unreleased prototypes, and even a card game if you’ve got printer ink to burn. Grab it free on Steam. I feel smarter just having it on my PC. (more…)
Zachtronics book Zach-Like shows how the puzzle sausage gets made
2019-02-07 19:45 UTC · Rock, Paper, Shotgun · contact@rockpapershotgun.com (Dominic Tarason)
I reckon most of the RPS Treehouse gang love us some Zachlikes, since well before Alice Prime coined the term in 2016 in reference to Shenzhen I/O. Puzzlemeister Zach Barth likes the term too, as he’s borrowed it for the title of his book. Currently crowdfunding on Kickstarter (500% funded in one day), Zach-Like shows the workings and the processes behind his practical puzzlers. There’s design docs for his major games, sketches and documents for some that never got made and some early design exercises. There’s even some pen-and-paper brainteasers in there, because we’re

Purchase a printed copy of the SHENZHEN I/O manual!
2018-12-04 23:40 UTC · Community Announcements · krispykrem
It's probably years too late, but we've uploaded the SHENZHEN I/O manual to Lulu so that you can order a professionally printed and bound copy (no binder, though). The quality is pretty good, and at $4.99 plus shipping it's not a bad deal! http://www.lulu.com/shop/zachtronics/shenzhen-io-manual/paperback/product-23899820.html
The 10 best hacking, coding and computing games
2018-11-26 10:12 UTC · Rock, Paper, Shotgun · contact@rockpapershotgun.com (Synonymous Bosch)
We’ve been hacked! As well as a fake festival of online retail excess, Cyber Monday is now a celebration of hacker games and everything ‘cyber’. This is the hAcKeR collective {{Synonymous Bosch}}. We have taken control of this aRt1cLe. Three years ago it was written by the untalented and scurrilous journalist Brendan Caldwell, a man lacking in both knowledge and substance. But we have gained access in order to correct his egregious errors. It s a hack of a hack! Ha ha ha. We had our best joke cell work on that for three nights. Please laugh. Our detractors may say Mr Caldwe
