More Swordfish
I posted another classic Sudoku that requires Swordfish/XWing solving technique. You should practice this technique because at some stage I might post a Killer Sudoku that will require you to use this technique to solve the puzzle. Maybe. ðŸ™‚
Of course I also posted another Killer – it’s a Brain X.
Have fun.

dear DJ,
i am sorry to say, that i do not understand this solving technique. i have tried to apply it without success. i am afraid that i am missing something important. Could you please try to explain again?
thanks, Ana
Hi Ana,
You shouldn’t worry too much about Swordfish/XWing because they are really advanced techniques and also they are very rare and even more difficult to spot.
I posted a further explanation in this comment here:

Maybe reading that would help. I hope you do figure it out this time :).
Cheers!
