Please, I am looking for puzzles with the "diagonal rule".
I give an example of a solved one:
2 9 1 4 7 8 6 5 3
8 4 3 5 6 1 9 2 7
5 7 6 2 9 3 1 8 4

1 8 7 9 2 4 3 6 5
6 3 4 1 8 5 7 9 2
9 2 5 6 3 7 4 1 8

3 1 9 8 4 2 5 7 6
4 5 2 7 1 6 8 3 9
7 6 8 3 5 9 2 4 1

Please note the diagonal line, from the corner starting with "2"
(2 4 6 9 8 7 5 3 1) and the other diagonal line from the corner starting with "7" (7 5 9 6 8 4 1 2 3). In this variant form, the positions in this diagonal lines are marked with a differente color, so you can see it better!
Note that in these diagonal lines, the number also can not be repeated.

Any one of you know this tipe of puzzle, and where can I obtain it?

Many thanks!
