Irregular sudoku rules apply. (Put the digits 1-9 once each in every row, column and region.)
Kropki: Digits separated by a black dot have a ratio of 2:1. Not all dots are necessarily given.
The entire 9x9 grid is a magic square (every row column and both main diagonals add to the same number). In the center of the 9x9 magic square is a 7x7 magic square. In the center of that is a 5x5 magic square. And in the very center is a 3x3 magic square. The dotted lines clarify the positions of the magic squares.
Solution code: Row 1 in the sudoku.

Amazing construction. Having done a puzzle with a little similarity (Welcome to the palindrome 2) recently this solved pretty smoothly. Thanks!

Wonderful puzzle. It's very cool that it was even possible to set, and it's set perfectly. I'm glad CTC featured it

Pure coloring/lettering magic. Thanks (it seems everyone always talks about coloring - working on paper I rather stick to lettering, not having a box of caran d'ache at my disposal)
