Begin your cosmic journey in Universe Architect, a blend of simulation and tycoon games, where you explore space from the very beginning – the Planck Era, right after the Big Bang. Similar to the sandbox exploration found in My Little Universe, here you’ll discover elements, unveil isotopes, and even trigger star explosions to expand your universe, shaping it as you wish. In Universe Architect, you play as Mr. Strange, a unique quark with unprecedented powers. Venture through the mysteries of space, tackling humanity's biggest questions: What came before the Big Bang? How is the universe expanding? Could you reveal the secrets of quantum gravity? Guided by these timeless questions, explore the tiniest scales of the cosmos, down to the Planck length, discovering particles like bosons, tachyons, neutrinos, quarks, and photons. Key Features: - Craft Your Own Universe: Trigger cosmic reactions, create heavy metals within the intense furnaces of stars, and use these elements to unlock new crafting possibilities. Transform these resources into complex planetary structures and stellar bodies, creating a playground as vast as a galaxy. - Build and Expand with Idle Gameplay: As a space idle game, Universe Architect allows you to build structures that automatically harvest elements, process materials, and generate new stars. With proper structure management, you’ll see your universe grow and thrive, from individual particles to entire galaxies! - Nurture Life and Civilization: Explore the fascinating possibilities of evolution by developing planetary ecosystems and giving rise to intelligent life. Manage environments to encourage the growth of new cells, cultivating them until they form entire civilizations across planets. Shape the course of history, influence technology, and witness the transformation of simple organisms into advanced societies. - Educational Adventure in Astronomy and Cosmology: Universe Architect is more than a game; it’s an educational experience that immerses players in the world of astronomy and quantum physics. The gameplay introduces complex ideas like singularity, the multiverse, dark matter, and quantum fluctuations, with concepts made accessible through interactive storytelling and challenges. - Feel Like a Star Maker in a Sandbox Universe: Similar to Stellarium, Universe Architect is a sandbox simulation where players can explore the wonders of space. Lay the groundwork for stars, planets, and even galaxies, crafting an intricate network of celestial bodies. The freedom to experiment and create makes this sandbox experience truly cosmic. Whether you're crafting galaxies, building planets, or guiding civilizations, Universe Architect offers the ultimate simulation experience for fans of space, astronomy, and tycoon games. Expand your universe, delve into the mysteries of the cosmos, and see if you have what it takes to become the ultimate architect of space. Your involvement in the game and the expansion of the planetary systems can lead to the birth of life. Nourish the new cells and cultivate their environment to eventually create a vast civilization. Can you do it? Educational Integration: Beyond being a captivating adventure, Universe Architect serves as an educational tool that helps players understand the complexities of cosmology, physics, and philosophy in an immersive and engaging way. The game introduces concepts such as singularity, the multiverse, dark matter, and quantum fluctuations through interactive storytelling and gameplay, making these advanced topics more accessible and memorable. In this space idle game, players will have the ability to create life on planets and guide its development, nurturing it as it evolves into powerful and advanced civilizations. Shape the course of history, influence the rise of technology, and watch as your creations grow from simple organisms into thriving, intelligent societies across the galaxy. ## Key features - Craft your own universe - Build and expand with idle gameplay - Nurture life and civilization - Educational adventure in astronomy - Sandbox space exploration ## Pricing and in-app purchases Base price: Free. **One-time purchases** | Purchase | Price | Type | | --- | --- | --- | | Level Pass | $7.99 | one-time | | Skipits Pack Small | $1.99 | one-time | | Skipits Pack Medium | $4.99 | one-time | | Hydrogen Small Pack | $0.99 | one-time | | Hydrogen Medium Pack | $2.99 | one-time | | Hydrogen Large Pack | $4.99 | one-time | | Helium Small Pack | $0.99 | one-time | | Helium Medium Pack | $3.99 | one-time | | Helium Large Pack | $7.99 | one-time | | Electron Small Pack | $0.99 | one-time | | Electron Medium Pack | $2.99 | one-time | | Electron Large Pack | $4.99 | one-time | | Tachyon Bundle Large Extra | $49.99 | one-time | | Star Core Pack Small | $1.99 | one-time | | Tachyon Bundle Large Extra | $46.99 | one-time | | Tachyon Bundle Medium Extra | $19.99 | one-time | | Tachyon Bundle Medium | $18.99 | one-time | | Tachyon Pack Medium | $4.99 | one-time | | Tachyon Pack Large | $9.99 | one-time | | Tachyon Bundle Small | $8.99 | one-time | ## Recent user reviews (4 of 4) All indexed reviews: https://appshunter.io/ios/app/sandbox-universe-architect/id6475395327/reviews.md ### 5/5 — Great game so far! *2026-02-10* Great game! I also had no problems so I’m just recommending some features for the next update(s). 1: I think there should be an editor to evolve your microbes, I don’t really think there should be that much parts just to make the cell phase pretty simple in the editor. 2: There should also be an option to control a singular member of a species, I would call this option something like “Guide” or smth. 3: Just to specify what the “Guide” option would do, the main purpose of the “Guide” option would be to help increase the population of the species, And that’s pretty much it! Other than all of that, great game so far! ### 5/5 — Love this game *2025-12-10* This game is fun and great and educational ### 2/5 — I like it *2025-07-12* Nice idea but my only problem is that the loading screen for the start won’t load please fix this👌 ### 4/5 — Fun so far *2025-07-12* I was on the sub Reddit for iOS games or something like that like a month ago and “pre ordered” this game and was so excited to see it finally came out. This is a fun game if you’re on a road trip or at school/work and want something fun to play on your phone. I’m really liking the game so far ## Frequently asked questions about Sandbox ### What is Sandbox: Universe Architect?
