The X and The V Squared: Anniversary Edition

(Published on 17. February 2026, 09:19 by .proxz14)

A year ago I published my first puzzle on this platform, and felt like celebrating that today. So, here is a direct sequel to that puzzle, with a similar theme but a trickier rule set.

Rules:

1. Normal sudoku rules apply: Place the digits 1-9 in every row, column and 3x3 region once each.
2. Digits along a line may repeat and must sum to the attached value.
3. XV: Digits separated by an X sum to 10, while digits separated by a V sum to 5.
4. Cells separated by a chess knight's move can't contain the same digit.

Very fun! I had one restart from faulty logic, and then smooth coloring from there

Congrats and thanks for this fun puzzle, which I rate 3 stars!

.proxz14's response: Thanks for the solve! I agree with you that its 3/5 on difficulty, and its quite surprising to see that it's been rated 4 so far, but I reckon it will reach 3 in the long run.
