The experts are the only ones I left unfinished as I have been trying to solve them unsuccessfully without greens. I'm going back knocking them off with greens until I workout the more difficult logical solutions.
off to try an old expert
one less now, still needed greens and a guess
Difficulty score 16. No green.
TallMike: I have just updated my table of scores. By my count there are a total of 508 expert puzzles here.
Thank you, drwho. I now have some counting to do. I will post my result.
Have you all tried Babble? It can be challenging sometimes
I'd say EZPZ. But it had an interesting and pretty open unique rectangle, which was probably not necessary to find. 14.
My count of the expert puzzles I have completed came to 179. drwho counted a total of 508 experts to date. I therefore have about 329 more experts waiting for me in the archives. It seems that my previous estimate of 380 was off by about 50, or 15 per cent of the correct number.
The great news, of course, is that I have fewer experts left to do than I had estimated.
