What's New
This update brings the complete Skytrax system with 31 new parts, a redesigned building experience, and helpful visualization tools that make creating and watching tracks even more enjoyable.
Version 2.8 · · 81.9 MBLatest
The new ball-path visualization and shadow system help you see exactly how your designs will work before you roll. Plus, fresh Skytrax blueprints give you plenty of starting points for your next creation, and the improved rotation options make building feel smoother and more intuitive.

GraviTrax is a physics-based track-building simulation where you construct marble runs using gravity, magnetism, and kinetic elements. On a PC, you trade the constraints of a phone screen for a workspace where you can see your entire track layout at once, manipulate pieces with keyboard and mouse precision, and run longer building sessions without interruption. The app's free editor lets you experiment with endless combinations, then watch balls navigate your design from multiple camera angles: all from the comfort of a desktop.
Bringing GraviTrax to your computer opens up a natural way to design tracks without the friction of mobile controls. A larger display means you see more of your track at once, making it easier to plan multi-level courses and adjust piece placement with a mouse. Longer play sessions become practical when you're seated at a desk, letting you iterate through ideas without the battery and heat concerns of a phone.
Building Tracks with Physics in Mind
GraviTrax centers on a core mechanic: construct a course where balls roll from start to finish using the laws of physics. The app includes construction elements that use gravity, magnetism, and kinetic energy to move marbles along your path, and players drawn to the pocket galaxy gravity sandbox side of physics will find familiar principles at work here. You're not just snapping pieces together: you're solving a puzzle where each component's position and angle affect how the ball behaves. Players report enjoying the engineering vibe and the problem-solving depth, especially when designing intricate multi-stage tracks that combine different element types.
Designing and Testing at Your Own Pace
The free editor in GraviTrax for Windows PC lets you build without time pressure. Place pieces, adjust heights, and experiment with new configurations until your track works the way you envision it. Once you've set up a run, watch the marble navigate your design from several viewpoints. The app offers different camera angles and visual styles, so you can observe the marble's journey from above, the side, or close up: useful for spotting bottlenecks or dead ends in your design before you commit to building it in the physical toy.
Exploring Track Possibilities and Expansions
The app includes content tied to the physical GraviTrax system: starter kits and expansion sets that exist as toy products. If you own physical pieces, the app helps you preview what they can do. If you don't have the toy yet, you can test ideas in the simulator and see which real-world sets would unlock your vision. The sheer number of available pieces means the design space stays fresh; players highlight how many combinations are possible and appreciate that the app doesn't overwhelm you with ads while you experiment.
Immersive Viewing Modes and Multi-Angle Replay
After you run a track, GraviTrax lets you replay the marble's journey from different angles and with different visual themes. Some users mention enjoying the graphics and the option to change backgrounds or marble styles, which adds a layer of customization to the viewing experience. If you have compatible VR glasses and a phone, you can even watch the run in Virtual Reality: a feature that brings an extra dimension to the build-and-test loop, though this works best when your phone is mounted rather than held in hand.
From Digital Design to Physical Building
One of GraviTrax's core strengths is that it bridges digital and physical play. You design a track on your computer, test it thoroughly in the app, and then use that design as a blueprint when you have the real toy pieces in hand. Players who own the physical set report using the app to try out pieces they just received, test combinations before committing them to the toy, and even plan what expansions to buy based on what they want to build. This workflow (simulate first, build second) transforms the app from a standalone game into a practical planning tool for the physical system.
How to Download and Install GraviTrax for PC or MAC:
Select an Android emulator:  There are many free and paid Android emulators available for PC and MAC, few of the popular ones are Bluestacks, Andy OS, Nox, MeMu and there are more you can find from Google.

Finally, download and install the emulator which will work well with your PC's hardware/software.
- Open the emulator software from the start menu or desktop shortcut in your PC.
- Associate or set up your Google account with the emulator.
- You can either install the app from Google PlayStore inside the emulator or download GraviTrax APK file and open the APK file with the emulator or drag the file into the emulator window to install GraviTrax for PC.
You can follow above instructions to install GraviTrax for PC with any of the Android emulators available.
FAQ
Do I need to own the physical GraviTrax toy to use the app?
No. The app's free editor works standalone, letting you design and test tracks entirely in the simulator. However, the app works best as a companion if you own or plan to own the physical toy. You can experiment with ideas digitally, then build them with real pieces once you have the set.
Can I start a marble anywhere on the track, like in the real toy?
Currently, the app places marbles at designated start points when you run a track. This differs from the physical toy, where you can release a marble from any position. Some players have requested the ability to start marbles anywhere, which would expand the testing possibilities.
What are the camera angle and replay options?
After running your track, you can watch the marble's journey from multiple viewpoints: overhead, side angles, and close-up perspectives. You can also change visual styles and backgrounds during replay, letting you customize how the run looks without changing the track itself.
Is the app free, and are there in-app purchases?
The core editor and most content are free. The app does include additional paid expansion sets that mirror the real toy's expansions, allowing you to access more pieces in the simulator. You're not required to buy these to enjoy building with the base set.
Does the app work without an internet connection?
The app functions as a simulator, so you can design and test tracks offline. Sharing, downloading community designs, or accessing certain online features may require a connection, but basic building and play work without it.
Can I use a keyboard and mouse on PC to build tracks more easily?
Yes. When you run GraviTrax on a PC, you gain mouse precision for placing and adjusting pieces, plus keyboard shortcuts for faster navigation. This makes the building process smoother than using a touchscreen, especially on larger, more complex tracks.
