i don't know if this is the right place to post this topic...
write the number in the empty boxes, the sum of the numbers in columns and rows is 264 ( maybe in diagonal too)
number that you can write are :
11 61 81 91
16 66 86 96
18 68 88 98
19 69 89 99
i couldn't fill this completely
thanks for any help
Hello, the prince!
Here's one solution.
. .
Note that the two main diagonals have a sum of 264,
so do the 2×2s in each corner,
and the 2×2 in the center,
and the four corner cells.

I did not use trial-and-error; I used logic.
If you insist, I'll explain my approach.
Nice! I'll start saving up some scratch for thisQuote:
