Seeing Doubles Sudoku

(Published on 11. April 2021, 02:46 by JWWJ2525)

Normal Sudoku rules apply.

  • No bifurcation needed.
  • Digits in circles must sum to digits along the connected arrow.
  • Digits must increase from the bulb in thermometers.
  • Digits in solid gray circles (including bulbs) must be odd.
  • Digits on gray lines must form palindromes.
  • Digits in cages must not repeat and must sum to the value in the upper left of the top cells in the cage.
  • Digits along a diagonal must sum to the value in the margin.
  • It's just as important to know where doubles aren't as it is to know where doubles are.
  • If you want to make the puzzle easier, I provide two more given digits after the puzzle below.

The solution code is wrong, can you fix it? Nice puzzle!

I am quite sure I have a valid solution, but the solution code gets marked wrong. Could you please check that you have written in the right code?

Also, I think you meant to write 6, not 2, when it comes to the two optional extra digits? The puzzle breaks immediately if you place a 2 in those cells
