Sum In, Sum Out
(Published on 23. October 2026, 01:13 by starchacer)
Here is my latest puzzle. Thirteen regions and nine arrows should make this a decent snack for most of you. I hope you enjoy. As always, feedback is welcome and appreciated.
- Normal Sudoku Rules: Fill each row, column, and 3x3 box with the digits 1-9 once each.
- Arrows: The sum of the digits along an arrow is equal to the digit in the connected circle. Digits along an arrow can repeat if allowed by other rules.
- Killer Cages: Digits in cages must not repeat and must sum to the number in the upper left corner of the cage (if present).
- X: Cells separated by X must sum to 10.

Solvable for a well advanced beginner. I used some set theory to solve. So i gave it 2.5*
