Any tips on how to solve them? I start off with words like 'piano' and 'lemur' to get some idea of which characters to include, but after that it just seems like a brute force challenge? E.g. let's say 'piano' gives you 0/1 and 'lemur' gives you 1/0, how do I proceed from there? I'd know that the word will contain one of 'lemur' in that exact position, and none of the others. Likewise one of 'piano' but not in that position. So the number of combinations possible right now is 5x(5x4)=100, each with 3 open slots that can contain 26-8=18 other characters. So 100x18x18x18=583200 options. And I only have a few guesses left. So let's see if we can narrow it down with a word like 'jumpy'. I'm already screwing up now because I've used the letters 'u' and 'p' before already. Let's say 'jumpy' returns 0/0. Did this narrow a lot down for me? I now know that we can ignore p and u, which means our options went down from 583200 options to 216000 options. If I keep this up, I might get down to roughly 14000 options by the final line. Granted that only a few of these will be valid words, but still more than enough options to randomly guess. So far I have not been able to get more than 1 letter correct.
