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): 2.29/day in the week to Sep 10 → 5/day in the week after.
For scale, across Steam · Top Sellers · Brazil over the last 30 days: the 24 chart moves that followed a price cut of more than 20% went a median of 9 places towards #1, and the 2,404 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.

Provavelmente o jogo mais nerdola que já joguei na minha vida, pra gostar disso aqui você tem que ser cracudo de jogo de puzzle e algoritmos. Não é pra todo mundo, mas se você se encaixa nessa galera tenho certeza que você vai gostar.
太雅致了

Overall the game has many positives, However for a game like this, there are a few MUST HAVES that are not present here. 1. There is no way to break instructions into sections 2. There is no way to request that a certain section only be carried out once or X number of times 3. Hovering over most things, does not always tell you what it is. 4. In the instruction menu, if you want to copy-paste large sections of instructions due to issues 1. and 2. you can only paste in small visible sections, you cannot drag to the right and select everything in that direction, you really have to do it bit by bit. 5. It is relatively simple to keep costs and area low, however to improve your cycle score this will take far far more skill than is reasonably necessary to complete the level, you can beat the level low cost first try but try and do a high cost high speed machine and it will take you many many hours and no real reward other than relief that it is over. THE GAME IS A GOOD GAME BUT THESE ISSUES HAVE TO BE ADDRESSED BEFORE I COULD RECCOMEND IT TO ANYONE WHO JUST WANTS TO PLAY SIMPLY AND NOT NEED TO CONSTANTLY COPY AND PASTE EVERY LITTLE PART IF THE SOLUTION INCLUDES ELEMENTS THAT ONLY NEED TO BE CARRIED OUT A CERTAIN NUMBER OF TIMES, OR IF THE REPEATED SOLUTION DOES NOT WORK.
Opus Magnum is my first game in the production genre (or however this games are called). I've always thought that these games should suit my puzzle and optimization coded brain but no game ever called to me. That is until I looked a little more into Opus Magnum and tried it. It really is a great game and most of the puzzles are completely solvable with enough thinking, unlike many puzzle games where it gets to a point that you have to spend days with each one and it becomes tedious. The style and vibes are also pretty good.
Good puzzle game.
dangerously good game. Hiiiiiighly recommend. I've decided the best approach to interacting with this game is one puzzle a day.
Good Puzzle Game. It is not for me.
你说得对,但是 《11408》 是由 王道/天勤 自主 编排 的一款全新 考研组合。 体系 建立在一个被称作 「计组」 的 层次结构 中,在这里,被 冯诺依曼 所 束缚 的 指令 将被 CPU 「译码」,导引 数据 之 流。你将扮演一位名为 「进程」 的 生命体,在 内存 的 汪洋 中邂逅 OS/网络 们,和 Cache 一起击败 缺页中断,找回 原语 ——同时,逐步 构建 「文件系统」 的 秩序。
this game makes me feel both like a genius and an idiot simultaneously
Игра знает как нажимать мои кнопочки. Если программирование - хобби, а не работа, то это самая подходящая игра
