Has anyone ever actually spotted a Swordfish...?

[Mr Growser...]

No, not the thing in the sea; the three-column beast in an evil, beastly Sudoku!

I can just about understand an 'X wing', but the one above....

....er - noooo...!

Any tips anyone?

Sudoku is a closed book to me I'm afraid. I've got an engineering degree, a computer science masters and an MBA and it's just gobbledygook to me, yet my OH has no further education and can do them in no time

I play Sudoku but had to google to find out about Swordfish and X wing, me i just do the puzzles starting by finding either all the ones or all nines depending how i feel. Didn't know there were other ways to go about it. might have to read up

Never heard those terms but looks like I do some of it without realising it (just Googled). Do puzzles sometimes to calm me down and stop me worrying / stressing.

I like Sudoku but never heard of a Swordfish - I'm intrigued!

[muddled]

I do sudoku and find them very relaxing (which is a bit odd because I have very bad dyscaluliar) However, I just gurgled sudoku swordfish and that does NOT look relaxing....

Not relaxing AT ALL

I hope this link works: -

We started a few years ago now, and Mrs Growser buys a book of all levels, and does the lot, one by one as a relaxer!

I like the idea of doing them without marking the candidates for each square, and it becomes a challenge, as well as a brain exercise - which I need at my tender age..;0)

However, an 'X wing' and a 'Swordfish' seem impossible without writing the possible numbers in, but I've seen people actually do it, so I suppose, like getting to Carnegie Hall, 'I'd better practice'!
