Normal sudoku rules apply. In box 1, for a digit N in that cell, there is a 1 in the same place in box N. For example, if there is a 9 in the top left corner, then there is a 1 in the same place in Box 9. The same rules apply for 5s in Box 5 and 9s in Box 9.
They gray square is a magic square; each row, column, and diagonal sums to the same total. Digits in cells connected by a white dot are consecutive. Digits in cells connected by a black dot are in the ratio 2:1. Not all dots are given.
Solution code: Column 3 and Row 7 (no spaces)

I wish it was easier to see the break-in (it was a pretty bad struggle for me personally), but the next phases of the puzzle were very enjoyable. Thanks so much!

Not too challenging if you have done magic squares before, though I could not easily deduce the break-in without making separate hand written reference notes. I really enjoyed the 1-5-9 constraint, good idea and well set.

Fun puzzle. It took me a little while to get started, but that just makes it all the more satisfying when the solve is completed. Great interaction between the constraints.

Thanks Shing Gaming. After the tricky opening, the middle part was smooth. Thanks also to the CTC software that saved me a lot of time in the endgame.
