Empty Prime

Normal Sudoku rules apply.
If a cell's row+column is prime, that cell must contain an odd digit.
For all odd digits, itself plus its 180 degree rotation counterpart must add to 10.
Red arrows point to diagonals that must add to a perfect square (1,4,9,16...). Not all are necessarily given.
The blue arrow points to the diagonal on which the nth digit along the diagonal tells you the index in that column the digit n appears. ie if the fourth digit along the diagonal is a 6, the number 4 is in the 6th position in that column.
4's cannot be a king's move away from another 4.
Lösungscode: row 1

Rules are a bit of a mouthful, but it was pretty fun to solve. Felt kinda like 2 puzzles in one, since the odds and evens are so immediately separated.

The rules are a mouthful, but once you get going it's a very smooth solve. Unless you make needless mistakes.

Great puzzle, I really enjoyed the symmetry that arose. Also, how dare you make me do sudoku in a sudoku puzzle (it took me too long to do the last logical step finding that Y-wing...)
