FV-pento-sudoku challenge

As we want to be part of the latest rage, but foremost because we are addicted ourselves, our new challenge is a sudoku.
With lots of thanks to Aad van de Wetering.

If you want to practice a bit with 5x5 sudokus you can click here or you take the site of Bob Harris.
First we had to select a suitable 10x10 field.

We chose this one:
FV Pentomino-field
It is the only tiling of a square with 10 F and 10 V pentominos and in addition it has a rotational symmetry.

So, each area (in the same colour) that must hold the digits 0 to 9 is formed by one F and one V pento.
FV-pentomino-sudoku

In the above square, in each field put one of the digits 0 to 9. In every row, in every column, and in every decamino, use each of the digits 0 to 9 exactly once. Nineteen numbers have been filled in already, these are not to be changed, of course.

We usually use Excel for finding the solutions. We have already prepared a file that contains our challenge.

If you think our sudoku is easy, you can always try to solve a Ukodus+ on Aad's site.
