Minecraft, but the blocks are triangular prisms
This is not a vanilla “build a triangle out of cubes” tutorial; this page is about LAirHisson's PrismCraft, where the blocks themselves are triangular prisms. Not Prism Launcher, not a Minecraft modpack, not play.prismcraft.online.

Not a “how to build a triangle in Minecraft” page
Search results for minecraft triangles and minecraft but triangles are often vanilla build tutorials: stairs, slabs, and cubes arranged to look like a triangle. This unofficial page is not that. PrismCraft changes the cell itself.
Cubes vs triangular prisms
In Minecraft, the world is a grid of cubes. In PrismCraft, the unit is a triangular prism: two triangular ends and three rectangular sides. That single swap is the whole pitch — Minecraft, but the blocks are triangular prisms — and it is why triangular prism minecraft queries land on this prototype instead of a redstone build guide.
A cube stacks on six faces. A triangular prism meets neighbors on different edges, so slopes and seams read as geometry, not as stairs made from cubes. This explainer does not host a clone and does not copy official art.
Other triangle-voxel experiments
PrismCraft is not the only triangular-prism voxel experiment. Names such as Trianglecraft show up in the same search cluster. They are useful as contrast: other people have tried triangle voxels. This page is only about LAirHisson's itch.io HTML5 prototype. It does not copy those projects' art, names as a brand, or worlds.
If you want to play, use the official itch.io build — not a Minecraft server, not a modpack installer, and not this guide.
