Thank you to Flinty for this wholesome series and for trusting me with the Christmas Dutch Flat Mates. I’m happy to be a recurring guest in the series and I hope it will continue for a long time to come.
If you are interested in the Dutch Flat Mates series created by Flinty, you can find the others here.

Normal sudoku rules apply.

• Dutch Flats : Every 5 in the grid must have a '1' directly above it or a '9' directly below it. It may have both, but it doesn't need both.


• X-mus : Clues outside the grid show the sum of the X cells nearest to the clues where X is the the digit on the opposite side of the row or commun to the clue.

An example is given below :

The puzzle is available online via CTC-App and Merry X-mus !
