Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: Games in Early Access are not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We are improving the learning curve by listening to your feedback. Our goal? Quantum eSports. As we grow, we’ll shape new competitive modes based on player insights.”

Approximately how long will this game be in Early Access?

“It can be anywhere between 3 months to a full year, given what sort of requests we get from the community.”

How is the full version planned to differ from the Early Access version?

“- Improvements to what we show on the puzzle completion metrics
- Additional tools for designing quantum puzzles
- Weekly/ Monthly tournament play modes
- Additional puzzles that expand on the core experience.”

What is the current state of the Early Access version?

“Bug free, fully playable in a highly polished form, following a successful closed beta, the game offers 50+ story modules (over 50 hours of canon content), upcoming esports tournaments, a sandbox “quantum simulator,” a complete narrative, collectibles, and infinite community-driven endgame content.”

Will the game be priced differently during and after Early Access?

“Yes, we offer a discounted price for those who buy it during Early Access and contribute to improving our game.”

How are you planning on involving the Community in your development process?

“I am active on our Discord and reading any in-game submitted feature requests.”

Reviews

“I find the game fascinating. It breaks my ego and absorbs me at the same time. When I start it, it obsesses me. I find myself staring, sometimes for up to an hour on the same puzzle.”
Notebook of a Strategist

“Simply by playing a game, you will learn about quantum computing without any particular educational background. There will not be a math quiz on Monday. Just play the game a little bit more and see what else you learn.”
Quantum Technology News

“This is not your typical puzzle game. This is a triumph of design, a game that dares to explore complex scientific concepts in a way that is both engaging and accessible.”
Cloud Gaming

About This Game

Welcome to Quantum Odyssey: the most ambitious project to place quantum physics, logic, and the building blocks of classical and quantum computing into the hands of anyone who loves a good puzzle. Built by scientists and in active development since 2019, it continues to evolve with no end in sight.

The Quantum Age Has Begun. And It's Time To Have Fun

What if mastering quantum computing felt like solving the most satisfying puzzle game you’ve ever played? That’s the goal. 

Quantum Odyssey an open-ended puzzle adventure featuring 55 branching learning paths, 357 handcrafted logic challenges woven into a light sci-fi story, community-built content, player-vs-player hacking, and a sandbox where you design your own algorithms using real quantum logic and play with linear algebra.

It’s as creative and flexible as the best engineering games, with one twist: you’re actually learning quantum physics and how both classical and quantum computers work.

No background in math, physics or programming required. Just your brain, your curiosity, and the drive to tinker, optimize, and unlock the logic that shapes reality.

The Quantum Engine Behind the Game

Quantum Odyssey is likely the world’s only full Hilbert space visual simulator for universal quantum computing. In simpler terms: it doesn’t just show what’s happening now. It shows everything that could happen, across all possible inputs. You see the full spectrum of quantum computation in real time as you change it. Every operation of a universal gate-model quantum computer is implemented with 11-decimal precision and with proper handling of floating point errors. The gameplay translates the raw math (linear algebra and complex numbers) into intuitive, visual logic anyone can grasp through direct experimentation. You’re in full control to design custom quantum gates, entire algorithms, or even gates that are algorithms. The game teaches you how to think like a quantum engineer and rewards you for optimizing algorithms.

A sci-fi narrative with multiple learning paths guides you from the fundamentals of quantum computing to building the most well-known algorithms and ultimately challenges you to invent your own.

The core mission of Quantum Odyssey is to show the world that designing quantum algorithms isn’t out of reach. Our hope is to reveal that the real barrier was never the complexity, but the cryptic math notation and the absence of tools for intuitive experimentation. This game breaks that barrier by turning the entire process into pure visual logic. The math is still shown for those who want to understand it.

In Sandbox Mode, you can freely explore and experiment with all quantum phenomena, like entanglement, superposition, and interference and truly see how the quantum world works and build anything you want, including challenges for other players to complete.

By playing, you’ll begin to feel the elegance of linear algebra and complex numbers through visual logic. We hope it opens your eyes to how beautiful math can be, and helps you let go of any fear you’ve ever had of it.

Real Quantum Computing, Zero Experience Required

Solve elegant logic challenges using real quantum gates (Hadamards, CNOTs, phase shifts, any square matrix... unitary or not) and quantum state vectors exceeding even the capabilities of today’s quantum hardware. All brought to life in intuitive visual form to reveal universal logic that was once buried in abstract math.

There’s rarely a single, correct answer: every puzzle is a system to explore, break, and rebuild. Discover shortcuts. Beat your past self. Or invent something completely unexpected.

With deep, flexible mechanics, collectibles and scoring system reminiscent of Zachtronics, Quantum Odyssey rewards both creative chaos and ruthless efficiency.

This Is the Moment. Learn Quantum Now.

This isn’t just for STEM.
Quantum Odyssey teaches the very logic that underlies reality itself: the laws of information, the emergence of complexity, and the strange, beautiful patterns that Nature follows. Everyone deserves to grasp this new way of thinking.

Supercharge your skillset.
Whether you're in science, engineering, or software, quantum literacy will put you ahead of the curve... and soon, it may not be optional.

The revolution is already underway.
Learning quantum today is like learning to code in the 90s. Those who understand it won’t just use the tools of tomorrow. They’ll build them.

And this is the best way to start.
There’s no better time than now, and no better launchpad than Quantum Odyssey. It’s the most fun, intuitive, and complete bible of quantum computing ever made.

By the time you finish, you won’t just know quantum.
You’ll think in quantum.
