Wichtel 2017 (4): Drei Wichtel und 144 Häuser
(Published on 26. May 2018, 07:04 by wichtel)
Three gnomes and 144 houses
As every year before Christmas a lot of organisational problems have to be mastered in order to get the presents to everyone in time. Currently Santa Claus is considering about the supply of 144 houses, which are divided into 12 rows and 12 columns. Since these are too much for one single person to take care about, he decides to let the delivery be done by three gnomes.
So he calls three gnomes, gives each of them one puzzle in hand and speaks:
"Here I have for each of you a map of the area, you three shall take over. One of you draws a loop and takes the houses inside the loop. The second has a Tapa puzzle on his map; he takes the houses on the black cells of the Tapa. And the third solves the LITS puzzle on his map and takes care of the houses on the black cells of the LITS."
"The puzzle has no unique solution at all!", all three gnomes exclaim at once, shortly after looking at their respective puzzles.
"Of course you have to have in mind, that each of the 144 houses is visited by exactly one of you", answers Santa Claus. "It makes no sense, if a house is visited more than once, and of course it mustn't happen, that a house is not supplied at all. To make the orientation for you easier I have drawn four dots in your puzzles, which have no further meaning."
With all this information the gnomes find out without difficulty, which houses have to be supplied by whom and Santa Claus can think about the next problems ahead.
Solution code: Row 4 and column 3: for each house the gnome, who supplies it (loop = 1, Tapa = 2, LITS = 3)

Fascinating and very instructive puzzle, and I think easier than 5-stars if you understand the global implications. I really enjoyed figuring it out :)

Es empfiehlt sich, ab einem gewissen Punkt alle "Häuser" in ein Raster zu malen. Waaaahnsinnsrätsel! Hut ab vor dieser Konstruktion!

Hut ab vor solch einer Autorenleistung. Allein fehlte mir bis vor einer Woche die rechte Betrachtungsweise. Im Hamburger LM-Bahnfahrerteam ging's dann.

Großartig! Aber der Weihnachtsmann sollte sich vorsehen, dass er nicht von einem der drei Wichtel wegen ungleicher Arbeitsbedingungen verklagt wird. :-)
