I have also tried the maze from a photo test a few times and never seen a one-shot success. But yesterday I was determined to succeed so I allowed Gemini 3 to write a python gui app that takes in photos of physical mazes (I have a bunch of 3d printed ones) and find the path. This does work.

Gemini 3 then one-shot ported the whole thing (which uses CV py libraries) to a single page html+js version which works just as well.

I gave that to Claude to assess and assign a FAANG hiring level to, and it was amazed and said Gemini 3 codes like an L6.

Since I work for Google and used my phone in the office to do this, I think I can't share the source or file.
