Put in each row, in each column and in each 3x3 block the number from 1 to 9. In addition cells mirrored at row 5 and col 5 must not contain consecutive numbers.
The 7 in r7c3 means: no 6 and no 8 in r3c3 and in r7c7. (The rule does not apply to doubly mirrored cells: 6[r3c7] is permitted)
Solution code: The 3rd and the 8th row.
