Times Superior Sudoku

Postby Crazy Girl » Mon Nov 21, 2005 12:33 am

Today's Superior Sudoku 17, was relatively easy, solving with a x-wing.

Can we have Superior's that are abit more tricky with another technique used to solve the puzzle, like a swordfish or colouring with 2 numbers
(ie. Numbers A and B in 4 cells, and where 2 of these cells meet, A and B can be eliminated, leaving the cell with a single number)

what did you guys think:?:

I agree that yesterday's Superior was much easier than usual but I did not consciously use an x-wing to solve it. Perhaps I had better try it again!

I would vote for a Swordfish, mainly because I have never seen one in practice yet.

i found that finding the X-wing (cols 1 & 9, rows 8 & 9, number=2) was the only way I could solve it!

That's exactly what i found, but did the puzzle take as long as any of the previous Superior Sudoku puzzles:?:

I found this one took roughly half an hour compared with some of the previous ones, that you could stare at for hours and still not see the next step:!:

The sunday puzzles you don't expect to be ' a quick walk in the park' but rather 'a long stroll'

agree... this one was definitly simpler than the previous ones... seemed a fiendish-like level

quite interesting to see the different ways we solve the same puzzle!

for me, the trio in c1 fixed the r7 2,
and there was never a need to look for an X-wing.

Having done it again, I agree that finding the 2s here was important. I suppose that I did not register it as an x-wing since it is all in the same row of boxes. I just thought that if the 2s are in rows 8/9 in box 7 and in rows 8/9 in box 9, a 2 has to be in row 7 in box 8. It is technically an x-wing though.
