Here's a puzzle I created for the 2022 Secret Santa event on the CTC Patreon Discord Server. Published here with the blessing of the Santee (gift receiver).

Normal sudoku rules apply.

Grey lines are palindromes, they read the same in both directions.

Adjacent digits along green lines differ by at least 5.

Digits along blue lines have an equal sum N within each box the line passes through.

Digits in cages sum to the clue in the top left corner.

Digits separated by a white dot are consecutive. Digits separated by a black dot have a 2:1 ratio. Not all such dots are shown.

Digits in grey circles are odd.

Have fun, leave a comment if you enjoy the puzzle!
