Voxel Games: History, Examples & How to Build Your Own
What makes a voxel game, why the genre keeps producing breakout hits, and a practical guide to building your own — from asset creation to engine integration.
Voxel games have produced some of the most distinctive titles in indie gaming — and a few of the most successful games of all time. The aesthetic is immediately recognizable, the design constraints are freeing rather than limiting, and the genre has a ceiling nobody has found yet.
This guide covers what voxel games are, why they keep working, the major subgenres, and how to approach building one.
What is a voxel game?
A voxel game is any game where the world, characters, or objects are represented primarily using voxels — discrete cubic cells arranged on a three-dimensional grid. The defining characteristic is that the game world is composed of discrete volume rather than continuous polygon surfaces.
This has gameplay implications beyond aesthetics. Voxel worlds can be modified at the cell level: blocks placed, removed, destroyed. Polygon-mesh worlds can fake this, but voxel worlds do it natively.
A brief history
Early voxel games (1990s) — The first commercial voxel games used height-field voxel terrain: a 2D grid of heights rendered as a pseudo-3D landscape. Comanche (1992) and Delta Force (1998) used this approach. It was fast to render and produced convincing terrain, but couldn’t represent overhangs or interior spaces.
The Minecraft moment (2009) — Minecraft redefined public understanding of what voxel-style games could be. It wasn’t just a game — it was a platform for creative expression. Its commercial success proved the aesthetic had mass appeal, and it spawned a decade of follow-on games and tools.
The indie wave (2010s) — With the aesthetic validated, indie developers explored what voxels could do beyond sandbox building: physics simulation, destruction mechanics, narrative games, strategy. Tools like MagicaVoxel (2012) made asset creation accessible to small teams.
Modern voxel games (2020s) — Today’s voxel games are technically sophisticated. Teardown (2020) uses a true voxel physics engine — every structure in the game is destructible at the voxel level in real time. Lego Bricktales and similar games have pushed the aesthetic into AAA production quality.
The main subgenres
Voxel destruction games — the physics are the game. Structures are built from voxels that respond individually to force, explosion, and collapse. Teardown is the genre-defining title: a heist game where you can knock down any wall, collapse any floor. The gameplay emerges directly from the destructibility of the voxel world.
Sandbox and survival — creative building with survival mechanics. Minecraft remains dominant, but games like Cube World, Hytale, and dozens of others occupy this space. The voxel grid makes procedural world generation natural.
Voxel detective and puzzle games — the aesthetic works for narrative and puzzle genres too, where the block-world feel supports a specific tone. Voxel Detective is a notable example of the genre — investigation mechanics in a stylized voxel city.
Strategy and management — top-down voxel environments work naturally for strategy games. The readable silhouettes and clear spatial grid make unit placement and territory legible.
Action and RPG — character-focused voxel games where the art style carries the personality. Crossy Road, OctaFight, and voxel RPGs like Voxel Quest show how flexible the aesthetic is across genres.
What makes voxel games distinctive
Beyond aesthetics, a few properties emerge from the voxel structure itself:
Destructibility — because the world is a grid of discrete cells, modifying it is straightforward. Remove a cell, add a cell, change a cell’s material. Polygon mesh games simulate destruction with pre-authored rubble states; voxel games do it dynamically.
Procedural generation — voxel grids map naturally to procedural algorithms. Noise functions generate terrain. Cellular automata simulate cave systems. L-systems grow trees. The grid structure makes these algorithms easy to implement and efficient to run.
Readable game spaces — the discrete grid makes spatial reasoning explicit. Players can count blocks, measure distances, and reason about geometry intuitively. This is why puzzle and construction games work so well in the aesthetic.
How to make a voxel game
Engine choice
Most indie voxel games are built on Unity or Godot:
Unity — large voxel plugin ecosystem (Voxel Play, Tri-Inspector, Voxel Busters). FBX and GLTF import is well-supported. Best if you’re already in the Unity ecosystem.
Godot — free and open-source. Native voxel terrain support improving with each version. GLTF import is first-class. Good choice for new projects without existing Unity investment.
Custom engine — technically ambitious projects (like Teardown) build their own voxel renderer for maximum control over destruction and physics. Only appropriate if the voxel simulation is itself the product.
Asset creation
This is where most indie teams spend the most time — and where AI generation changes the math.
The traditional workflow: model every asset manually in MagicaVoxel or Qubicle. A character takes hours; a full environment takes weeks.
The AI-assisted workflow: generate base models with Voxel AI, refine hero assets manually, accept AI output for background and environmental props. A session that previously produced 5 assets can produce 30.
For a game with significant asset needs — varied enemies, props, architectural elements — AI generation is the practical choice. The quality is sufficient for background and secondary assets, and the editor supports refinement for anything that needs polish.
Export and import
For Unity and Unreal: export as .fbx or .glb from your voxel tool. Both engines handle these natively. .glb is the lighter format and works well for large asset libraries.
For Godot: .glb/.gltf is the native format. Import is smooth and supports material assignments from voxel palette colors.
Voxel AI’s free tier is a good way to test whether AI generation fits your asset pipeline — 50 tokens lets you try a range of prompts before committing to a paid plan. Open the editor →
