X-Sum Arrows

(Published on 29. December 2020, 09:35 by Phistomefel)

This puzzle is a crossover of an arrow sudoku and an X sums Sudoku and it is inspired by Richard's fantastic Killer Skyscrapers Sudoku.

The usual sudoku rules apply. Each number outside the grid indicates the sum of the first X digits from the corresponding direction in the corresponding row or column, where X is the first number from the corresponding direction. The number in a circle indicates the sum of the numbers along each arrow arising from that circle. Numbers may repeat along an arrow. Numbers outside of the grid can be two-digit numbers.

The puzzle is also available online via Penpa Plus. Have fun solving!

Solution code: 5th row, 8th column (18 digits)

@Fedo: Thanks for the question! The clues outside of the grid can be two-digit numbers. I will clarify this in the rules.

Are all the clues outside the grid single digit or can be a 2 digits number?

Beautiful puzzle. Difficult to start, but then like onion layers it gradually reveals itself. Thanks, Phistomefel, for yet another gem !

Thank you for the feedback!

@udukos: This reminds me that your X-Sums Killer Sudoku still waits in my watch list for me to finally solve it.

The start was pretty challenging for me but fantastic puzzle.

Once past a certain point, it solves like a train. 3* but very nice. Thanks
