I solved today's Redactle (#37) in 365 guesses with an accuracy of 43.01%. Played at www.redactle.com/
That was hard - I got what the topic more or less was, but narrowing down to the right term was difficult (because I knew there was a word for something (subject-like in a few specific ways I won't go in to now) but I was damned if it came to mind - I had to break off and let it percolate up in its own time.
I really enjoyed 'foam' - it took me 897 guesses, but it was a really satisfying one. i was down a bit of a science-y silo for ages! Then tried 'beer' to fit the 'head of' bit in the first paragraph, and suddenly I was there. Love a denouement like that!
