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 23 chart moves that followed a price cut of more than 20% went a median of 14 places towards #1, and the 2,515 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.

I've got a wire, NAND gate and a 1 tick delay and now I'm designing my own Assembly language :O
Highly recommended if you have any interest in puzzle games, computers, learning something new, or challenging yourself. Aside from the fact that it is teaching you about how computers work, the puzzles are also just genuinely fun and interesting. The progression from basic components all the way up to a functioning computer is well-paced and incredibly satisfying. Really just an excellent game that I think everyone should try :)
Very fun game, especially if you already have some light experience with logic gate computers
Instead of spending $40k-80k to find out I don't understand anything, I spent $20. And, that's a win on its own.
Jeśli szukasz gry, która wciągnie Cię na setki godzin i nie pozwoli o sobie zapomnieć, to właśnie ją znalazłeś. Ta produkcja to absolutny pokaz slajdów genialnych pomysłów i perfekcyjnie zaprojektowanej rozgrywki! Co sprawia, że ta gra jest aż tak niesamowicie dobra? Głębia i personalizacja, która zwala z nóg: Projektowanie architektury procesora to po prostu poezja dla każdego fana planowania schematów. Ilość ścieżek, synergii i możliwości przypomnienia sobie czasów spędzonych w technikum na nauce elektroniki oraz logiki cyfrowej (od dłubania w bramkach NAND po totalną, bezwzględną dominację nad algebrą Boole'a na polu walki z układami) sprawia, że każda decyzja o dodaniu rejestru daje ogromną satysfakcję. Tutaj naprawdę czujesz, że Twój build ALU ma znaczenie! Uzależniający gameplay loop: Rozgrywka jest niesamowicie satysfakcjonująca, płynna i dynamiczna. Gra perfekcyjnie balansuje poziom wyzwania – kiedy przypominasz sobie podstawy z technicznych lat, aplikujesz odpowiednie modyfikatory skracające cykle zegara i zaczynasz kosić elitarne instrukcje asemblera, czujesz czystą, niczym nieskrępowaną potęgę. Syndrom "jeszcze jednego układu": Znasz to uczucie, kiedy siadasz na chwilę, by przetestować prostą magistralę, a nagle za oknem robi się świt? Ta gra robi to perfekcyjnie. Poziom immersji i czysta frajda płynąca z przekładania dawnej wiedzy elektronicznej na nowe kombinacje w walce z kodem maszynowym sprawiają, że od ekranu nie da się po prostu oderwać. Dopracowana, piekielnie grywalna i satysfakcjonująca na każdym kroku. Dla mnie to absolutne 10/10 i jeden z najlepszych tytułów, w jakie grałem. Kupować w ciemno, bo warto każdych wydanych pieniędzy! xD cD
If you enjoy working out logic puzzles and really want to know what's going on in the basic building blocks of any computer, this game is definitely for you. The best game I've played so far that goes through the fundamental concepts of computer architecture, great for the budding electronics engineer. The only ♥♥♥♥♥♥♥ is, if you're a complete beginner the concepts are not well explained throughout the game, and some vigorous external research is needed. But for a rusty engineer like me, it brings me back to the old days and certainly gives the brain cells a workout again. I'm playing the old version as my computer is not powerful enough to run the current version, but I look forward to trying out the updated version, another reason to upgrade my computer eventually!
I was recommended to play this game before I take another course in the university... It is fun to play and learn, BUT I really need to reflect this to the team: 1. I don't know if my settings went wrong, but somewhat my command window popped out and keep tracks of my game progress whenever I started and played game. 2. (I don't know if this is fixed or not, but I will still put it here) I started playing the game just by the time you guys made an announcement on your new update, i.e. late June, 2026. I noticed that there's a new version, so why not I just play with the new version? Especially when I noticed the game progress will not be synced between the 2 versions. But it turned out that I could not get any achievement in the new version. Does that mean I was FORCED to play the OLD version in order to get an achievement? Then a sub problem appears... So do I need to play on both sides in order to keep my game progress? (Even though I decided to stick to the old version though (for my achievements :P ) 3. Today (18 July, 2026), I saw the new version is finally published as the public version. That's great, so I went to see if anything is changed or added. Then there are immediately 2 issues I noticed. I'll put it as 3A and 3B. A. Why is the UI so small? I feel like all the gates are so much smaller than they were in the old version. I'm nearly blind looking at them. And why can't I just adjust the size in the options, just like the old version? Please, why are you removing an adjustable option in the settings? Is this really an update or a downgrade??? B. I am glad to see you guys adding a logic folder for the logic gates, but can someone tell me why is my folder keep closing itself? I tried to single-clicked the folder to keep it open, but as I placed some gates and did some circuitry, the folder was closed! It makes me so annoying when revisiting some foundational levels. I mean, the game initiatives are good. I learnt a lot of thinking from it, and I am grateful for that. BUT I would also hope that the developer team can be a little bit more considerate for the user experience. Thanks, and all the best to the further development.
