“In the years I've owned this game and the 677 hours at the time of this review I've put into it, Turing Complete has changed a lot, both for better and for worse. The game used to be, all things considered, relatively…”
“This is amazing. If you care about Computer Science, please get this game. I want to build a computer and make microslop go brankrupt now It goes all the way from "what is a NAND gate" to "What is the Call stack, what…”
“This is basically the classic Nand2Tetris course/Elements of Computing Systems book in the form of a video game. This is what a good Computer Architecture college course teaches you, gamified. Awesome. I cannot…”

“Really nice game, it teaches you the fundations of the engineering behind a computer. It's not easy but worth the time.”
“note: playing on the 2.0 alpha branch i love puzzles, and computers are just big puzzles. that being said, on the version of this game that i played, i feel like the pacing of puzzles showing how each component comes…”
“amazing game, it was really fun and although at first designing a cpu seems like a really daunting task the levels properly teach you how everything works and ramps the difficulty really well as you get to more complex…”

“This game has got me hooked i finished it in a few days. They walk you through building an actual working computer, people have build freaking RISCV in this game. The pacing is amazing it knows exactly when to hold your…”
“The first two hours flew by in the blink of an eye. Passed basic logic and some levels of arithmetic. Love it”

“insane game. Yes its still in early access, but the dev is actively workin on a 2.0 version (free beta). Playin it rn and its so good best game of all time, awakened my love for computers”
“1.0 was a good basis and 2.0 although buggy is taking it all the way while i disagree with many design decisions in 2.0 its overall in a good direction and worth the worse controls of the tradeoff between 1.0 and 2.0”
“great for who want to dive deep into computer architecture. The tips and hints had improved so that player can easily get help if he stuck in some where”

“the current [save_breaker] branch is what I recommend you play. Its a alpha (?) of the long planned 2.0 update by the dev. It takes whats already a great game about building a computer and completely overhauls the…”
“The new completely_broken version is very fast. The campaign is a bit bugy (updates are daily rn) and sometimes challenging, but very well paced. I love this game very much.”

“It's a good game, but as a colourblind person I would prefer the option to go to black and white, apart from the colourcoding of wires, and with the coloured wires named, because many of the default pallete are…”
“THIS GAME IS BASICALLY ABANDONED Dev swears up and down that a new version is coming, it's available on the beta branch. Both the normal branch AND the beta branch have severe game breaking bugs that make the game…”
“Very fun game, sometimes the instructions are not super clear, but it can be figured out. Learned a lot about basic computer architecture while having fun.”

“"1. My outlook Some developers release their game, their sales spike on launch day, then taper off and they subsequently abandon the game a few months later. That wont happen with Turing Complete. Turing Complete will…”
“It's really a shame the developer seems to have abandoned the project. The gameified version of this subject matter can substitute in for some elementary computer science courses, and give a much clearer understanding…”

“This Game could easily being used in every computer science course of study. I, for myself, have a degree in technical computer science and this game has many of the knowledge we learned in one course. Also it is very entertaining. On top it teaches you very subtle a very good…”
— a player, Steam review · 25 hrs played“This game is super cool. Actually, it's rather a 'build your own computer from scratch' simulator. And not only build, but organically figure out how to program this computer, and what, basically, is a program. You clearly will be able to see how complexity of systems bursts,…”
— a player, Steam review · 13 hrs played“As a long time advocate of computer architecture education, I am sad to leave a negative review of this amazing game. I have come back to play this game over many years only to be more frustrated every time I return. I will summarize what I love about the game (and…”
