About Anamo

Anamo is a free, browser-based guessing game for human anatomy — think of it as a geography guessing game, but the map is the human body.

What it is

Each round, Anamo secretly selects an anatomical structure and shows you an interactive 3D model. You guess structures by name; each guess is painted on the model in a heat color — white for far, deep red for very close, green for correct — computed from the real spatial distance between structures on the model. The result is a game that quietly teaches spatial anatomy: even wrong guesses show you where things are relative to one another.

Who it's for

Anamo was built for anyone who enjoys knowing what they're made of: students revising for anatomy practicals, nurses and physiotherapists keeping their knowledge sharp, gamers who like daily puzzles, and the incurably curious. Four difficulty tiers span from household-name bones to structures that challenge medical students, and the Anatomy Guide backs the game with plain-language articles about the structures you'll encounter.

The 3D models

The anatomical models used in Anamo come from the Open3DModel Project (AnatomyTOOL.org), created by the Open3DModel community and based on BodyParts3D and Z-Anatomy. The models are licensed under Creative Commons Attribution-ShareAlike 4.0. For use in the game, the GLB files were decompressed and per-structure metadata (names, positions, hierarchies) was extracted; in accordance with the ShareAlike requirement, those modifications are distributed under the same license.

How proximity scoring works

Every structure on a model has a centroid computed from its mesh vertices. When you guess, Anamo measures the three-dimensional distance between your guess's centroid and the answer's centroid, normalizes it against the size of the model, and maps the result onto the color scale. Structures that are anatomically adjacent therefore paint hot, and distant ones paint cold — no hierarchy tricks, just geometry.

Technology

Anamo is built with React and React Three Fiber for the 3D front end, a FastAPI backend, and MongoDB for aggregate statistics. It is deployed on Railway. The site shows advertisements via Google AdSense to cover hosting costs; see the privacy policy for details.

A note on accuracy

Anamo's content is educational and written for a general audience. It is not medical advice, and the game's simplified models and difficulty tiers necessarily leave out clinical nuance. If you spot an error — a mislabeled structure, a wrong fact in a guide article — please tell us; corrections ship quickly.
