3D spatial cube grid
Arkose / FunCaptcha 3D object
Select every cube with the target colour on top — a grid of isometric cubes rendered at random 3D orientations. Spatial reasoning (identify the TOP face of a rotated cube), not a 2D glyph; a correct selection faster than a human can scan the grid is automation, convicted on coherence.
This gate auto-serves on load — bring a browser, a bot, or your own solver and try to bypass it. You get two verdicts: did you pass the gate — and does Kitsune’s detector independently convict your client over the edge?
Difficulty is a cost dial, not a security dial — harder = more work, never a better bot/human test. The detector convicts at every level.

Detector verdict
What Kitsune’s coherence engine independently makes of your client over the edge. For your full fingerprint, run the detector.

The gate is just an HTTP protocol on Kitsune’s owned arena service (allow-list-scoped — it only ever talks to itself). Script a bypass against:
- GET
/arena/spatial - POST
/arena/spatial/verify
How this works & the ethics
The gate is a self-hosted service Kitsune runs (the owned arena service). It reproduces the
documented, open mechanism above — it never contacts, proxies to, or solves a third-party
challenge (Cloudflare Turnstile, reCAPTCHA, hCaptcha). The reference solvers only ever talk to our own gates. The detector
verdict comes from the same coherence engine that scores the home page, reading your client over the edge.
