XV Square
(Eingestellt am 17. Oktober 2021, 17:26 Uhr von dgreenspan)
Normal sudoku rules apply. Cells separated by an X must sum to 10, and cells separated by a V must sum to 5. All possible Xs and Vs are given. Cells separated by a chess knight’s move must contain different digits. The two digits in the cage, when read as a two-digit number, must be a perfect square.
Edit: As apendleton points out, the knight's move constraint is not actually necessary for this puzzle to have a unique solution.

"so I consider it a bit of a design flaw"
Unintended consequences can be just as much a source of beauty as intent. This puzzle was beautiful either way and I enjoyed it a lot, and I've been enjoying the recent trend on this site of more easy yet fantastic puzzles a lot, too.

Pretty interesting that you don't actually need the knight's move constraint for uniqueness. I definitely used it and it'd be harder to solve without using it

apendleton: You are right! Wow. That was not intentional, so I consider it a bit of a design flaw. I've edited the description to note this.

Very nice! I got a unique solution.

Correct me if I am wrong but I believe there is two separate solutions?
Edit - Sorry misread the last clue as the sum of the two-digits in the cage is a square number
