Today's Puzzle:

Another request I had received from an email. Harder than many of the weekend puzzles I feature, but immensely enjoyable. Give it a go!

Rules:

Normal Sudoku rules apply.

Cells separated by a knight's move (in chess) cannot contain the same digit. Cells joined by a white dot must be consecutive. Cells containing a grey square must be even. Cells containing a grey circle must be odd.

The Blue line is simultaneously a palindrome and a region sum line.

Digits along a palindrome line must read the same forwards and backwards. A region sum line has the same sum in every 3x3 box it visits.
