Hope you enjoy! :)
Links to the previous parts of the series are given after the rules.
Irregular Sudoku rules apply. Place the digits 1–9 once in every row, column, and marked region.
Anti-Knight: Cells separated by a knight’s move in chess cannot contain the same digit.
Palindromes: Digits along a grey line must read the same forwards and backwards.
XV: Cells separated by a V sum to 5; cells separated by an X sum to 10. Not all Vs and Xs are necessarily given.
Magic square: Somewhere in the grid lies a 3×3 magic square that contains all digits from 1 to 9 exactly once, and in which every row, column, and diagonal adds to the same total. It's up to the solver to determine the location of the magic square. (The magic square can occupy cells from different boxes.)

This went SO much better when I finally remembered the magic square!

I found this one very difficult. Took me ages to find the magic square. But I messed up along the way, so I restarted from the beginning assuming I was right about where the magic square was. It STILL took me an hour but I got it. A testament to it being a very nice puzzle that I stuck with it.

coloured all in aaand got an X-Wing :/ Couldn't see my mistake so I started over and it luckily resolved.
Love the series (not good at irregular sudokus, but there's just one way to get better, right??)
