Wichtel 2019 (5): Japanische Pentominoplätzchen
(Published on 25. August 2020, 05:01 by wichtel)
Japanese Pentomino cookies
In a good temper Santa Claus arrived in the in-house gnome bakery. He watched some time the lively ado and enjoyed a bit the tasty smell coming everywhere out of the ovens. He called for the chief gnome baker: "Have you finished the special pentomino cookies I've asked for? I want them next to be delivered." The chief gnome rummaged in his papers for the order and guided Santa Claus into the cooling room. He pointed at a baking tray "Here they should be." Santa Claus looked twice, cleared his glasses and took another glance. "Well, besides twinkling blue pearls I see nothing here", he said to the chief gnome. "Yes, of course!" protested the gnome "as ordered, three of each tasty butter cookies, sweet vanilla kipferl, juicy cinnamon stars and delicate German bethmännchen. All in the twelve pentomino shapes. Yet the assistant gnomes went wrong with the icing and so all the cookies have become invisible. Only where the cookies touch each other diagonally (elsewise they do not touch) the blue fairy dust keeps twinkling." "Duh", grumbled Santa Claus, "well, then I have to help a bit along." Now he took for his part his small box with the powder from the Japanese magic nut and sprinkled some in the baking tray. After inspecting the result he was satisfied: The numbers from one to nine were nicely spread, each number at most once in each row and column with black cells in between. And now you could find the cookies: Each cookie covered exactly one black cell and where it covered numbers, these were multiplied magically. At the butter cookies the numbers were doubled, at the vanilla kipferl tripled, in the case of the cinnamon stars quadrupled and under the thick bethmännchen even quintupled. So with the help of the outside sums, which respect the multiplied numbers, it was no problem to locate all the cookies.
Solution code: First the letters of the pentominoes (see Pentominoes), sorted first by factor and then by alphabet, the tenth row and the 12th column, S for black cells. If a pentomino is in a cell, give directly after the content (number or S) the letter of the pentomino.

@Zombie Hunter: First part of the solution code: Enter the letters of all used pentominoes with factor 2 alphabetically ordered. Then the same for all the pentominoes with factors 3, 4 and 5 similar. After this one row and one column as stated.
If you still don't really know what to enter, please tell more exactly, which detail you do not understand.

When I am too dumb to understand the solution code, I think I have to pass on this wonderful puzzle

@cdwg2000: Your solution code looks quite good in general. But the first part is missing completely and in the second part the Pentominoes are not given correctly.
First part: Enter the letters of all used Pentominoes with factor 2 alphabetically ordered. Then the same for all the Pentominoes with factors 3, 4 and 5 similar.
As second part the row and column as you've already tried, but add the Pentomino-letters for each single cell, where they are contained.
