Logic Masters Deutschland e.V.

I am very happy with how this turned out, and I’m amazed that this idea worked at all!

Rules:

Fill the grid with digits 1 to 9 so that digits don’t repeat in rows, columns and outlined regions.

Adjacent digits never sum to a number divisible by 3.

Digits separated by a white dot are consecutive.

Digits on a grey square are even.
