Tabula Rasa
(Published on 31. December 2021, 23:51 by apete)
Squares separated by a knight's move (in chess) cannot have the same digit.
Digits along the 2 main diagonals do not repeat.
The center box (#5) is a "magic square"*.
The middle square of each box (position 5) form a "magic square"*.
The odd digits in the central column (#5) increase from top to bottom.
The even digits in row 1 increase from left to right.
(*In a "magic square", the sums of all rows, columns, and the 2 main diagonals are equal.)

I have set my magic square values, used the column 5 clue to set my first digits, then used those to restrain my other magic square values outside of box 5, but all I have are a whack of pairs and no clue how to break in. :)
