Play this puzzle online at the Daily Sudoku site

With the 369 triple in box 6 I got to this with basics.
The 347 xy pivot r4c1 did the same trick as Clement's
249 followed by his setting 247. Just proves that you
don't always need all the basics!

So do I. But just as a personal preference, on these puzzles I try to use only the standard VH moves that are needed to solve them, i.e., X-, XY- and XYZ-Wings.

I used the same two wings as Clement.
