I recently started enjoying Sudoku again after finding Cracking The Cryptic. They inspired me to try making a puzzle of my own. I hope someone can enjoy it :)

1. Normal Sudoku rules apply.
2. Digits along an arrow must sum to the digit in the arrow's circle.
3. Cells separated by a black dot must have a ratio of 2.
4. Digits along a line are palindromic. They are the same forward and backward.
5. The cell with inward facing arrows (Row 7, Col 6), is the minimum of orthogonally connected cells.
6. The cell with outward facing arrows (Row 3, Col 4), is the maximum of orthogonally connected cells.

This puzzle was created using the F-Puzzles Sudoku setter.
