How to use this list
The list above is every word in the dictionary that fits, sorted so the ordinary vocabulary sits at the top. If you already know more than the pattern in the heading — a letter that is definitely absent, or one that is present but in the wrong place — the solver takes all of that at once and reproduces the game's own colouring rule, including the awkward case of repeated letters.
