### Times Superior Sudoku

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.
