About the Game
Replicube is an open-ended programming puzzle game/toy about writing code to replicate 3D voxel-based objects.
SOLVE PUZZLES
The main content of the game involves trying to match a reference object by working out code that will replicate it. There is no "right answer", if your code produces the same object, it's correct!
PLAY AROUND
You can always open the voxel tool in "free edit" mode and just play around, making whatever you want. In addition to the main 3D voxel editor, there is also a bonus 2D image editor for writing code to generate 2D images and GIF animations. You can even save your image creation as the background image in the "OS" interface of the game!
JOIN THE COMMUNITY
Every puzzle has 2 leaderboards, measuring source code size, and execution efficiency. Often optimizing for one will be at the expense of the other. If you enjoy trying to squeeze a bit more out of your code, the leaderboards are waiting!
There is also an in-game online forum where players can share their own voxel creations, and even challenge other players to try to recreate them, all presented in an old-school online forum wrapper.
EXPORT YOUR CREATIONS
Generated 3D voxel objects can be exported into common formats to bringing into other 3D creation tools.
Generated 2D images and animations can also be exported as png or gif for sharing online.

Version Information
Steam Patch Notes
Official update history
- Switched RepliCube to multi-threaded execution to speed up evaluating large objects / animated objects.
- You can now have as many code tabs as you want in Free Edit mode to have multiple in-progress projects as you want.
The first post-release patch is now live on Steam. This update mostly addresses bugs, but also has some new features. Here's a short recap of the changes:
- Added autocomplete to the code editor! It only knows about Lua keywords and built-in functions right now, autocompete for user variables or defined functions will come in a future update.
- Replipaint is now using multiple threads for a performance improvement
- Several improvements to how the game communicates with cubenet
- Fixed a few exploits with the token counting (code size) system
- when viewing a leaderboard, the game will now jump to your score first
- improved documentation formatting
I will be sharing my roadmap soon with my plan for future updates and improvements to the game as well, both in-game on cubenet, and here on Steam in the discussion forums.
Happy cubing!
