Palindromaze
A slightly simplified version of this puzzle appeared on CtC on Oct 28, 2021. The version of the puzzle depicted here is a hard version, although it has a completely logical solve path which does not require bifurcation. The solutions to the puzzle are the same in both versions, the CtC version simply has a few additional Kropki clues. I will include both links below, and you can determine which version you want to play. Or, if you have watched Simon's solve on CtC, take up the challenge and try the harder version.
Rules:
1. Standard: Normal sudoku rules apply.
2. Standard killer: Cells in cages must sum to the clue in the top left corner of the cage.
3. Standard palindrome: Lines in the grid are palindromes, which must read the same forwards and backwards.
4. Standard little killer: Cells along indicated diagonals must sum to the total given.
5. Kropki without negative constraint: Cells separated by a white dot are consecutive. All possible dots are not given.
6. Odd: Cells with a gray circle must contain an odd digit.
