More Swordfish

I posted another classic Sudoku that requires Swordfish/X-Wing 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. 🙂 Of course I also posted another Killer – it’s a Brain X. Have fun.

    Hi Ana,

    You shouldn’t worry too much about Swordfish/X-Wing 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 :).
