Hi everyone,
We’re thrilled to present a project we’ve been working on for a while now: a fully functional 4D sandbox game in Roblox, featuring:
- Real-time 4D space simulation (tesseract-based)
- Multiplayer support
- Persistent world saving (private servers)
- Voxel-based building and destruction in 4D
We believe this is the first complete implementation of a 4D voxel engine inside Roblox. All rotations, physics, and interactions are handled in four spatial dimensions, using 4D vectors and a custom edge-based slicing system.
What is 4D?
When we say “4D,” we don’t mean time. We mean an actual fourth spatial dimension, perpendicular to the three we experience in everyday life.
To illustrate:
Just like a 3D cube is a higher-dimensional analog of a 2D square, the tesseract is a 4D analog of a cube.
We can actually visualize 4D geometry using two techniques: Cross-section and Projection.

How does the engine work?
Our engine uses 4D vectors (Vector4) and renders 3D cross-sections of a 4D world.
We simulate movement and interaction by intersecting the edges of a tesseract with the player’s current 3D slice.
This allows for smooth 4D rotation, projection, and real-time transformation of space.
4D voxels
Unlike typical 3D games, our world is constructed from 4D volumetric blocks (voxels).
What you see is just a 3D slice of a higher-dimensional structure.
Every frame, a new 3D slice of the 4D world is rendered based on your rotation in the fourth axis.
4D changes how space works
Moving through the fourth dimension enables behaviors that are impossible in 3D:
- You can walk “around” solid walls by rotating in 4D
- You can see players who are hidden behind walls or inside sealed areas
- You can escape cages by rotating into a direction where the bars no longer surround you
Sealed houses aren’t sealed in 4D
You can build a house that appears fully enclosed in 3D with no entrances.
But from a 4D perspective, it often has gaps in the fourth direction, making it accessible after all.
However, it is possible to create a fully enclosed 4D building by stacking 3D “slices” of a house.
FUNNY DUMMY SLICE:
Thanks for reading!
This project was heavily inspired by 4D Miner by Mashpoe, which showed us how cool and fun 4D games can be.
We wanted to see if something like that could exist inside Roblox, and now it does.
