Normal Sudoku rules apply.
Antiknight - Squares a chess knight's move apart cannot contain the same digit.
Arrow - Digits on the arrows must add up to the digit in the attached circle.
Sandwich: Clues outside the grid give the sum of the digits between 1 and 9 in that row or column.
Solution code: Column 5 followed by Row 5

Fun fact: If you replace the bottom left 13 clue with a 16 instead, the puzzle has TWO solutions! (I totally didn't do that)

This was my first sandwich variant and I must say I enjoyed it a lot. It felt like a very natural solve. Great construction.
