X-Sums Arrow Circles
(Published on 19. April 2023, 18:03 by LittleNightmaresLady)
-Normal Sudoku Rules Apply.
-Digits along an arrow must sum to the number in the attached circle. For clarification involving box 7, r789c2 is one arrow and r8c12/r7c3 is another arrow.
-Clues outside the grid give the sum of the arrow circles in the corresponding row/column. The "10-22" and "1-14" clues mean the sum is between (but not including) the endpoints. For the purposes of this constraint, r9c5 is considered an arrow circle.
-In addition, they are also X-Sums clues - they give the sum of the first X digits in that row/column, where X is the digit nearest to the clue. With clues that are not of a specific value, the arrow circle sum and the X-Sums sum must satisfy the inequality/range but they do not necessary have to be equal to each other.
-An inequality sign points to the smaller digit of the two cells it connects.

Sublime! It seemed there was never any information at all and some of the clues did not do anything for the solve, until there was and they did. Thank you

Glad you liked it! I remember being happy about a clue that did something twice haha. Thanks for solving!

Awesome! And surprisingly approachable, given how sparse the constraint info was :)

Thanks for the solve and feedback!

Removed the dash from the right end of r2. It meant nothing.
