I might as well take this opportunity to plug my clone of Semantle which uses a tSNE visualization. I've heard many people say this helps them visualize the chains of logic in their guesses.
I think there's a really approachable game somewhere in this space, but it needs to implement something along the lines of an auto hinting system.
I imagine that for every guess, you could get a word or two that is similar (to help you understand what part of the word's context is important), and maybe words that are further away to help understand what isn't important?
Makes me wonder what 3D (or even 4D) version would be like.
