Normal sudoku rules apply. Digits in a cage must sum to the little number in the upper left, and may not repeat in the cage. Neighboring digits marked with V sum to 5. Neighboring digits marked with X sum to 10. Neighboring digits marked with a black Kropki dot have a 2 to 1 ratio. Not all Vs, Xs or dots are given. Cells with arrows pointing inward must contain digits less than all orthogonal cells. The cell with a grey square (no little arrows) must contain an even number. The number outside the grid indicates the sum of the digits on its indicated diagonal. Digits may repeat when otherwise allowed. Comments welcome! :-)
Solution code: First row of puzzle, and fourth column of puzzle (read top to bottom). Enter as a string of 18 digits, no spaces.

Had to restart a couple times due to breaking the puzzle, but eventually got it. Some tricky parts, but nice flow!

I struggled multiple times to solve this puzzle, but all the hard work brought finally a solution.
I would classify this puzzle as a 3*.
Thank you PDN

This was quite fun. The opening digit took me longer than it should have, but it immediately sets the stage for the rest of the puzzle. Thanks for sharing this!!
Edit: Thanks for giving it a go!

It has a very nice flow to it
Edit: Thank you - I strive for this, but don't always hit the mark. :-)
