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 2,402 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.

Fun if you already know a lot of this stuff. I wouldn't want to learn about most of this for the first time here though. If you don't know any of this stuff but still want to dive in, I'd recommend picking up the book Elements of Computing Systems or check out the (I think free) online Nand2Tetris course (the website is the companion to that book).
It's great - I got an A on my digital logic exam without studying at all thanks to this 'game'!

好玩,但不是说要在2025年结束EA阶段吗,不过反正都一样
Не только вспомнил хорошо забытое старое но и изучил немного нового и все ради того, чтобы сэкономить еще пару тактов ценой пары сотен вентилей. Однозначно рекомендую!
Really nice game, it teaches you the fundations of the engineering behind a computer. It's not easy but worth the time.
프로그래밍을 하는 사람이라면 한번쯤은 우리가 일하는 기계가 어떻게 생겼는지 알아봐야 한다고 생각합니다.
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 together is absolutely amazing, and the game doesn't hold your hand any more than it needs to. this isn't to say that it's easy, just that it really does help you learn by doing rather than telling you how to do something and having you replicate it. you are given the tools you can use, told what you can make, and you arrive at your own conclusion. 10/10.
这是一款十分简洁的游戏,其实只要找到了窍门还是不怎么难的。这游戏第二章最后有一关是不是出BUG了?
毎日8時間くらいやって10日間で全クリできたーーー! NANDって何ぞ?って所から、最後は自分のCPUでアセンブリまで覚えれたので、 専門学校の1年分くらいの勉強になると思います。
