A Sudoku With Only 4 Given Digits?!

cracking-the-cryptic.web.app/...
Normal sudoku rules apply. In addition, both marked diagonals must also contain the digits 1 to 9. Cells that are a knight's move apart (in chess) cannot contain the same digit. The central 3x3 box must form a magic square.

It's quite interesting how these knights move puzzles tend to end up rotationally symmetric. If you rotate the puzzle 180 deg and overlay it with itself, all cells sum to 10 (in other words, when reflected through the center point, all 1s land on 9s, 2s on 8s, 3s on 7s, 4s on 6s, and 5s land on themselves).

Here is the funny thing about this. This was the first video I ever watched on this channel. I didn't really even know about regular sudoku and never knew about these variants. I am also a fairly dim bulb when it comes to solving puzzles. This was so out of my league that I couldn't even understand it let alone try to get one number into the grid. But I have been an avid watcher and have been attempting to solve these puzzles every day since this. I decided to come back and try to solve this one just to see if I could do it without Simon's help. I did this puzzle in 17:04 and I was watching a basketball game that was distracting me on the side. This just shows what incredible teachers Mark and Simon are. I can solve about a third of the puzzles on here now, and with some slight miniscule help, can solve more than half.
