Arrow X Sudoku combines X sudoku, where diagonals must also use the set 1-9, with a set of arrows whose digits add to the digit in the arrows' circles.

Sure thing! I know every printer is different and worried they may be too dark, so I set it fairly low to begin with.

I would say just one notch darker, as I agree that too dark would be a problem too, especially with difficult puzzles like these where I needed to jot down lots of possibles in the boxes.

Thanks for the puzzles! I had to work on these for quite awhile, they were not easy. Of course, it might have helped if I had noticed and paid attention to the diagonal rule which I didn't realize until I was trying to figure out why one of the puzzles seemed to have a non-unique answer. Once I applied the diagonal rule there was only one solution. Might I suggest that the gray markings for the diagonal and the arrows be made just a little bit darker for future puzzles? I did not see the gray diagonal boxes on my printed puzzle and once I started adding markings the arrows were hard to see.
