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.

Reviews
good example of how level design matters in education!
Crash on level selection – worked fine yesterday. Tried everything: restart, reinstall, verify files, delete config, offline mode, change renderer, even asked my AI assistant. Nothing works. Steam API fails to connect too.

每个游戏关卡差不多是把如何从一个与非门到一台可以运行的计算机之间的步骤拆开,按顺序一路玩下来也不会太难,好玩!
This game genuinely unlocked a passion and shaped my career. Well made and recommend anyone to play this if you have interests in CS or CE.
好玩,但不是说要在2025年结束EA阶段吗,不过反正都一样
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?
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'!
Probably the only reason I passed my assembly course
Really nice game, it teaches you the fundations of the engineering behind a computer. It's not easy but worth the time.
