Hi all (especially Simes, who set this puzzle!)
We have been attempting to solve a puzzle found on http://www.simes.clara.co.uk/programs/sudokutechnique6.htm (xwing2), but are unable to see any xwings, and are unable to progress further than:
**1 853 6**
5** 24* ***
*** 79* ***
973 128 5**
285 964 317
**4 537 298
*** *15 ***
*** **9 **3
**6 3*2 4**
If anyone can give us a clue, it would be much appreciated, as we are getting very frustrated!
Thanks very much, Jen and Alex
