Replicube
Write Lua code that rebuilds 3D voxel objects
Replicube shows you a 3D object made of voxels, which are small cubes. Your job is to write Lua code that builds the same object. There is no single right answer. If your code produces the same shape, the puzzle is solved.

About Replicube
Each puzzle has two leaderboards, one for the shortest source code and one for the fastest execution, and these often pull in different directions. The game trains you to spot patterns in shapes and turn them into math and loops. It suits players who know some basic code. There is also a free voxel editor, a 2D image and GIF editor, and an in-game forum for sharing creations.
The game is made by Walaber Entertainment. It is a paid game on Steam for Windows, macOS and Linux, and you can try it free in your browser.
