given that you get feedback on every coordinate independently you can solve them all in parallel-- afai understand you should always be able to solve a 2^6 space, / 2 because you don't get green per coordinate, and / 2 because you don't get a directional hint on the first guess, so up to 16 is always solvable? This is even without the distance metric, right?

Sorry if I’m misunderstanding your comment, but your point is essentially correct: the puzzle can be solved using only the per‑coordinate feedback.

Since you mentioned “green,” I’m assuming you’re referring to Euclidle’s Absolute hint type. In that mode, each coordinate can indeed be narrowed down efficiently using a 1/2‑style strategy.

However, when the hint type is not Absolute — what I call Relative, where only directional information is provided — the situation is different. Because the feedback is purely relative rather than per‑coordinate, the simple 1/2 strategy does not directly apply.
