Yes it's interesting, precisely because it's intuitively "solvable" by machines. There's joy in solving by hand, and joy in creating a solver, but probably no joy in running your solver every day and sharing with your friends. Because every decision is some maximum-likelihood estimate, there's no tension or drama in the sequence of guesses. In fact, simply the act of creating an infallible solver (100% likelihood of 6 guesses or less) demonstrates the futility of competing with their soft, fleshy skills. I do think any solver that uses the solution-set is "cheating", but I suspect it makes little difference in the total solution (like... 2-3 bits of additional information needed, just a fraction of a round).
