A little bit of everything (XV sudoku)
(Published on 27. September 2020, 01:30 by Lisztes)
Normal Sudoku rules apply. Each row, column, and 3x3 box contains each number from 1 to 9 exactly once.
The even numbers (2, 4, 6, 8) cannot be a knight's move away from each other (2s from 2s, 4s from 4s, etc).
All orthogonally adjacent cells with the sum of 5 are marked with a V, and with the sum of 10 are marked with an X. This is also a negative constraint (where there is no V or X between the cells, the sum of the 2 cells is not 5 or 10)!
Digits along the thermometers must increase from the bulb end.
The grey "snake" with the yellow background is a palindrome, which means it is a sequence of digits which reads the same backward as forward (for example: 1234321).
The puzzle is also available online.
Solution code: Row 5 and Column 9

Really nice flow, maybe I got lucky but it felt like two stars for me. Never done even only knight’s constraint before, nice idea.

I was finally able to solve this puzzle! I tried it and got stuck at least 5 times. Today for some reason everything went smoothly. Thank you, I (finally) really enjoyed it.
