I like to thank all testers on the Sudoku Stream Team and CTC discord servers. Special thanks to Calvinball and SamuPiano for early testing and helping me find a good title for the puzzle. As always, your feedback in the comments is much appreciated. I wish you joyful solving and a Happy New Year!
- Normal sudoku rules apply, i.e. each row, column and 3x3 region has to contain the digits from 1 to 9 once each.
- Quadruple: Digits in a circle must appear in the four surrounding cells.
- Region Sum Lines: Box borders divide the blue lines into segments with the same sum. (Different lines may have different sums.)
- XV: Digits joined by a V sum to 5. Digits joined by an X sum to 10. Not all XV are given.
Here you can solve the puzzle online:
Solution code: Column 1 from top to bottom (9 digits in total)

You have such a talent for constructing puzzles which are challenging but not impossible, straightforward but not trivial, difficult but not tedious. I am always joyful when there’s a new sujoyku puzzle to solve :)

Thank you for your kind words, dingledork! I mostly prefer easy to medium difficulty puzzles. Probably, that reflects in my own setting. It is great to hear that you enjoy my puzzles.
