Place the digits 1 to 9 in every row, every column and every 3x3 standard block. The numbers in the marked regions are the sums of the digits in these regions. No digit can be repeated within a sum.
Each of the digits 1-9 does appear twice in the blue marked cells.
Cells connected with a "2x2"-move could not contain same digits. An example: when R5C5 (Row 5, Column 5) contains an 8, there could be no 8 in R3C3, R3C7, R7C3 and R7C7.
Solution code: Row 1, followed by column 9

Happy new year, Eisbär!
After a while I got stuck, and then decided to read the rules again. I forgot the last rule.
I shouldn't have printed the diagram without the text....
But it worked (almost) without T&E. Amazing puzzle.

I also needed T&E. At our next 'stammtisch' we have to discuss the logical way through the puzzle! ;-)
