19 clues, horizontal and vertical symmetry, it is the first of this kind that I see:

Nice puzzle Mauricio, it takes a Y-wing/W-wing/semi-remote-pair to solve.

After singles and pairs:

Code: Select all: *--------------------------------------------------------------------* | 8 569 *46 | 1 #36 2 |-3459 579 34579 | | 45 569 1 | 7 36 8 | 2 59 3459 | | 7 3 2 | 4 9 5 | 8 6 1 | |----------------------+----------------------+----------------------| | 29 7 35 | 26 1 34 | 4569 8 4569 | | 6 4 8 | 5 7 9 | 1 3 2 | | 29 1 35 | 26 8 34 | 4569 579 45679 | |----------------------+----------------------+----------------------| | 1 8 7 | 3 2 6 | 59 4 59 | | 345 56 9 | 8 45 1 | 7 2 36 | | 345 2 *46 | 9 45 7 |#36 1 8 | *--------------------------------------------------------------------*

There is an XY-wing but it doesn't solve the puzzle. Instead you can use the Y-wing with the {36} in r1c5+r9c7 and the strong link on 6 in r19c3 to eliminate 3 from r1c7, thus reducing the puzzle to singles. :idea:

Quite. But, as far as I know, Claudia produces these little gems by hand, so hats off to that!
