Prices
Each in the currency that store quoted — not converted: the gap between two rows is the publisher's pricing, not an exchange rate.
Every market we collect.
Charts
Each storefront's own chart, in its own country — the closest public signal to sales where none is published. A country missing from a list is one we don't collect there, not one where the game doesn't chart.
No United States chart position — it charts only in the markets below.
Latest in each market: best FR #86, worst PL #97 · 2 markets collected
Discounts
Every price cut of more than 20% we have observed, in each market that quoted one, with this game's chart position on either side of it. These are episodes, not a model: a sale is one event, and one event cannot tell you what the next one will do.
Reviews, worldwide (the counter carries no country): 3.71/day in the week to Sep 10 → 12.29/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 26 chart moves that followed a price cut of more than 20% went a median of 7 places towards #1, and the 2,400 moves with no price cut behind them went 2 away. One store, one chart, one country — it is the only place we have enough observations to say even that.
Prices outside the United States have been collected since 6 August 2026 and chart positions since 19 July 2026, so a cut older than that has no market to compare and a market that joined later has no history yet. Nothing here is converted between currencies.

You developers frustrated me with the recent update. Not only did you wipe my original save because you are too incompetent to implement safe progress transfer but now progressing back to my previous level is painfully slow and repetitive. Now not only do you have to progress through the game, but they force you to take these stupid quizzes in order to progress where you essentially have to replay all the previous levels again. Its dumb and an annoying game mechanic that is pointless. Just let me play the stupid game I paid for instead of repeating stuff over and over I literally just did. Way to ruin a good thing.
I'm playing it for the first time and I'm having so much fun! If you're interested how computers work I can highly recommend this game. The skill tree makes it way more approachable than other simulators that only have a sandbox mode. Also it runs super smooth on my old 2017 Thinkpad, so I can play from the couch :)

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 recommend this enough if you have any interest in computers, logic, philosophy, traditional architecture or systems thinking, or math (esp. discrete math or concrete math). It will pay dividends everywhere, it changes the way you think about things, you'll catch yourself composing complex ideas down into a series of sequential logical expressions, making it easier to understand complex ideas, and easier to detect when someone is pulling a fast one on you to convince you of something untrue. I haven't finished the game yet but I plan on using it to refresh/reinforce the ideas I learned in computer architecture, and maybe try a more ambitious final project than my very buggy snake game.
Вставляет не по-детски. Не для слабонервных. Рекомендую
Lol pretty awesome. Simulation on the new version is really good. I built an RISC-V CPU and ported doom on it.. And it runs in-game. Turing complete is really crazy :D
很硬核的游戏,比我想象的难,但也比我想象的容易
Perfect introduction into computer architecture even for a beginner, this game doesn't directly tell you information but rather guides you into figuring out everything yourself, this way you actually end up remembering much more and actually fully understand what you've build in the end.
this game is golden, and i dont write reviews
The best *game* I've ever played. Its actually a highly effective Educational Simulation.
I also have issues with the way the game is designed on a fundamental level. First off, you have to go into the settings to enable latches, which is a pretty fundamental computing concept to hide behind a setting. I also have issue with the way memory is implemented with the delay line. I suppose it's supposed to represent a bit of DRAM, but the game makes no real mention of it, and there's pretty good reason why basically every single computer engineering course on earth initially teaches memory using latches instead of delay. Absolutely nothing is really explained, you're kinda just thrown into the deep end and expected to swim, which then begs the question, who is this game for? It's too basic for your average CS student, but too complex for a complete beginner. If you want a similar game that's better (and free) nandGame is good, and nand2Tetris is a fantastic learning resource EDIT: game is no longer abandoned, however the newest update has completely broken the game and I can't even get past the title screen anymore without the game crashing. absolutely incredible work, i have literally no idea how you manage to release something in this bad of a state.
