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.

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.
About
Understanding the fundamental logic that governs our Universe and learning how to harness it with quantum computers is one of the most powerful skills of the 21st century. It shouldn't belong to a select few.
This non-linear, story-driven open-ended puzzle universe runs on the actual laws of of quantum physics. This game respects your intelligence and its complexity ranges from fully guided tutorials designed for absolute beginners to brutal quantum-algorithm puzzles that takes days to solve and asynchronous PvP battles where anything can happen. Every mechanic, story beat, and puzzle trains real, in-demand skills used in Quantum Information Science.
This decade-long project is developed by the scientists behind the key papers that defined "Quantum Literacy." It is a research-backed game that teaches counterintuitive quantum thinking the way humans learn best: quietly in the background, while you’re immersed in an addictive, fully interactive sandbox. NO AI was used at any stage of its development or in the writing; we stand firmly against the use of generative AI in any creative work.
100+ hours of content: 70+ modules, 500+ visual puzzles, 300+ pages of interactive encyclopedia
Asynchronous PvP: hack other players creations, make content, climb zachlike leaderboards
Full sandbox mode: build any classical or quantum system, import to visualize any algorithm
Boolean logic: bits, classical operators, adders and how to port to quantum equivalents
Turing-complete quantum logic: qubits, complex numbers, linear algebra, custom gates
All phenomena: superposition, interference, entanglement, measurement effects, noise
All techniques: phase kickback, amplitude amplification, phase-to-signal retrieval
Famous Algorithms: Deutsch–Jozsa, Bernstein–Vazirani, Grover’s Search, QFT
Everything is learned from scratch, in full detail, through gameplay alone. This goes deeper than classes, textbooks, or exercises ever could because you are free to interact in any way you please with the quantum phenomena you learn.
Finish the game and you'll be able to separate quantum hype from reality, know where quantum computing excels at (and where it doesn't), read field papers with confidence, form your own informed views on the technology. Most importantly, you will be able to design and think up your own quantum algorithms for any problem you choose. The industry desperately needs people from diverse backgrounds to think of new solutions. This game equips you to be one of them.

Interesting game. Some concepts are hard for me to grasp but the explanations are clear and the difficulty is going up slowly so you can catch up with the pace easily.
I like your quantum abacus, magic man
This game has massively improved my understanding of Quantum Computing, Quantum Mechanics Principles, and general "illogical" logic.

Love this game. I havn't been this engaged in anything in a long time.
So far I am loving it. I started with curiosity because I was interested in knowing how did this interface even related to quantum computing, but once I got it I ended up hooked. The visuals do a really good job in portraying your algorithm flow and the aids in the UI (tables, matrices) are very much appreciated. It is also really nice that you can choose how much deep do you want to go in the quantum shenanigans, and still enjoy the game. My only criticism is that if you want to dive into the whys and hows of the quantum stuff that is below the gameplay, the encyclopedia feels like an overwhelming rabbit-hole because of the lack of order. The contents are very complete and newbie friendly at the same time yes, but oftentimes I ended up there from a link in one of the sages dialogue to check what something was, and I ended up lost in a web of deeper links without really knowing which ones I was suppoused to look at first. That is the only thing I would love to see here, some kind of topological sort on the contents if you wish to dive deeper. (I found a link in the Discord to a video that was very good at explaining basic quantum stuff and its relation to linear algebra, but I still think that something like this should be in game too).
Quantum Odyssey is ideal for fans of logic puzzles and quantum mechanics. While phenomena like entanglement, superposition, and tunnelling can be difficult, the game makes learning them enjoyable, especially their logical and mathematical sides. Focus on the puzzles or dive into quantum concepts as you wish. Whether you’re a novice or an expert, Quantum Odyssey offers something. Most players will learn something about quantum mechanics, regardless of their starting knowledge.
发现是25年1月发行的游戏,只觉得晚买了1年 奇观般对称的美感,从顿悟到顿悟,这才是知识锁游戏 中间的名人名言也选得精妙,颇有与先贤对话,启迪智慧的感觉 爽玩本游戏需要一些计算机科学基础,尤其是线性代数部分
Before I get to the game, major props to the dev who is present and engaged with the community. I don't think I've seen a thread on the Discussions page where they have not contributed in some way or another. Super rare to find someone who is obviously skilled [b]and[/b] patient when dealing with people. I assume this is a one-person project, and for that, they have my absolute respect. The game itself is something I should have bought a long time ago. I got it during the Cyberpunk Fest and absolutely devoured it from day one. The graphics are great: super sleek, not overwhelming, and modern (I often wonder if quantum physics should have a steampunk look to it, given that it was born in the 1920s [or in 1900, whichever you like]). The way the map unfolds after having solved a level is super satisfying, which is a healing balm after some of the puzzles really kicked the wind out of you, but in the nicest, most exciting way possible. (Oh, I should mention I have a little background in the subject. More on that later.) I don't see this as just a game, and like the developer, I want to internalise, to the best of my ability, the intuition of quantum computing, which is its principal selling point. It has not been easy, but the process of trying and learning has been rewarding. I expect it to be this way with the number of puzzles there are to solve. I would love to read some experiences from people who have mastered the game enough to picture the unitary processes as clear as day (down with the Bloch!), or how they have used this game on their end. Having said that, there are some issues that need correcting, but they are not unknown to the developer. It's their [url=https://store.steampowered.com/news/app/2802710/view/679633323166795099]latest post[/url] that got me to write this review to begin with, and one can only wait to see the changes that are to come. Having a background does make it easier to begin with momentum. The in-game explanations can get a little hard to follow; not conceptually, purely in terms of peculiar sentence construction. With a little (or a lot) of effort, I think the playground eventually evens itself out, but I can see why people can get frustrated. There are only so many games/media one can consume in a lifetime. But much like p-sets/problem-solving assignments, this too must be a team effort and not merely a solo activity. Whether you make the group online or out in the real world, the challenge is a feature not a deterrent. But with the dev being a genuine lad, and there being a passionate community, what more does one need?
Despite the slightly mediocre story and graphics quality, this game hits FAR above its weight in actual complexity and depth, as I'm sure many other comments can attest to. I'm hoping it keeps developing as it someday escapes early access - this is an amazing passion project!
I have no idea wtf I'm doing but seems legit. I'm trying to reconcile GR with quantum mechanics from scratch so I have to learn it first. Starting with this game.
