I solved today's Redactle (#78) in 564 guesses with an accuracy of 49.47%. Played at www.redactle.com/
Essentially I got it in 170 (when I had the last two words inside the brackets in the first sentence) but just could not think of an alternative term. Also, I thought I'd tried the second word of the title early on - turns out I hadn't!
So when stuck I had a diversion and just tried to fill in as much of the article as possible. That was fun!
