 It would be a lot of fun to visit this place! That is quite a statue! 20/Oct/07 12:31 AM Wonderful statue. Have a terrific weekend, everyone! 20/Oct/07 1:10 AM Made some stupid mistakes today. But in my favour - it's very late. If you mark it up wrong.... you're doomed! 20/Oct/07 1:17 AM I think I found a short one-step proof for this puzzle. Given 23, UP 31. At this point, a7=37. If 7, then c9=3, e7=3, d2=3, g1=3, a4=6, leaving no candidate for a1. Therefore a7=3. UP 81. 20/Oct/07 5:20 AM Fabulous statue. Good photo. 20/Oct/07 5:24 AM I didn't do the puzzle today, but I think the photo is great! 20/Oct/07 6:36 AM I only have time to do the puzzles on some weekends and lunchtimes - but not every day. But I try to always see the pictures. There's a confession for you! I usually only do the Hard and the Tough. 20/Oct/07 8:01 AM I have done, and mostly do do all the puzzles, and there's is sad confession also! 20/Oct/07 8:41 AM 16:22 Very slow! 20/Oct/07 10:37 AM 8.10 Fairly straightforward!Me too Bluey, tragic aint it. 20/Oct/07 11:21 AM Is that Mercury with Pegasus? 20/Oct/07 12:42 PM 7:38 (a record time for me!!!) This was possibly the easiest tough puzzle ever. Hidden pairs take you a long way. My solution was very similar to Rich's in that it resolved the triple a147=367. Starting with the assummption a1=3 you quickly reach a position, where there is no legal place for a '3' in the lower right box (= region with center h2). 20/Oct/07 8:36 PM Where is it? 20/Oct/07 11:54 PM 13:57 10/Nov/07 11:21 PM Woo Hoo!! 15:34 27/Nov/07 1:05 PM SE=6.6 07/Sep/10 9:33 PM
