Just wondering, are there any advanced techniques that are reliable/faster to use other than x-wing, swordfish, and xy wing? I wanna hit an extreme time of less than 3 minutes, so far my best is 3:35 with no helps used. I don't know how legitimate the scores are but if the 1

x times are real then pretty sure I can hit 2

x times as well.

Can you explain what is x-wing swordfish and xy wing?

I get good times on easy, medium and hard but on on extreme I rarely make the leaderboard.

I would love some tips and if you could explain x-wing, swordfish and xy wing then I can compare with what Im doing and let you know if its different.

sorry I don't know how to explain it but I found a website that explains them.

my friend taught me the techniques I mentioned. the website does show a few others I never learned, but I think they take more time if used.

X-wing is the most useful and I had a variation of it before I was told about it. the xy-wing is the one I see a lot in the extreme puzzles.

OK. Here goes. You can solve more than 90% of the extreme puzzles here without anything more than basic techniques. You have to practice your pencilling systematically and pick up the easy numbers along the way. Not much to it but quick thumbs!

[b]with any OTHER Sudoku puzzles, EXTREME MEANS
1)HARD LEVEL but with the twist added that NUMBERS DIAGONALLY ARE NOT repeated...making an X OF the numbers 1-9 .
