> Hard Mode: Any revealed hints must be used in subsequent guesses
As implemented, hard mode doesn't count gray letters (letters nowhere in the solution) as hints. You're allowed to reuse gray letters, but true hard mode should prevent that.
Oh hmm, I've never thought of gray letters as hints, more like the absence of hints.
Some wordle clones handle this correctly, like https://term.ooo (Portuguese language)
In his example he knows 3 of the colours as indicated by yellow but he also knows that those letters are not in those positions and hard mode let's him make bad guesses using those letters in the same positions again when it shouldnt
But hard mode only says the guesses must be used, not that they mustn't be used in the same spots.
My understanding is in hard mode, you are not allowed to make a guess that you know is not the right answer. So you cannot use a letter in a spot where you know that letter does not belong.
Hm, yeah, you're right, that makes the most sense.
