Friday Puzzle #96 - Arrow Sudoku  
Back to my normal offerings after a week off to become the voice of a new puzzle audiobook series (which you should check out if you missed it). This week I've written an arrow sudoku that looks a bit like a spring flower. Enjoy!

Rules: Place a single digit from 1 to 9 into each cell so that no digit repeats in any row, column, or 3x3 bold region. Digits in the circled cells represent the sum of all digits along the path that the arrow travels, and can repeat within a sum provided they obey other sudoku rules.

Nice grid with a very fluid resolution, Thomas !
If someone want a harder version of the grid (without breaking the aesthetics), try to solve this grid without the 2 in column 2 and the 3 in column 8. I've tried and, if not mistaken, it has also a unique solution. But it becomes a very hard grid, you'll sweat to solve it ;).

Thanks. Yes, that change (to make an even more symmetric grid) is valid but I found it a bit too hard even for my "Friday Puzzles." Giving that 3 in the upper-right seemed essential to have a smooth solving puzzle.
