That's a very cool stack! Just by coincidence the first word that came
up for me was "garden". However, when I saw the scrambled letters, I
saw a true, one-word anagram for "garden", "danger". Let's not get
into the psychological reasons for that ;-P So, it now seems
another enhancement would be to check for one word anagrams of the same
set of scrambled letters. :-)
