Normal sudoku rules apply. Any two cells separated by a knight's move (in chess) cannot contain the same digit. Digits along an arrow sum to the digit in that arrow's circle. Lines are palindromes.
Solution code: row 1 followed by column 2 (18 digits, no spaces)

Freaking awesome puzzle! Had so much fun with this. Took ~30 min, but felt like 5. Great setting.
