Reciprocal Lines
(Published on 23. August 2022, 23:02 by randomra)
Normal sudoku rules apply.
On each golden line reciprocals of the digits must sum to an integer. (E.g. if the digits on a line are 1, 2, 4, 4 the reciprocal sum is 1/1 + 1/2 + 1/4 + 1/4 = 2 which is an integer so the line is correct.)

Solution code: Row 5 (left to right), 9 digits long with no space

Ein sehr schönes Rätsel, auch für Nichtmathematiker. Man muss halt ein bisschen tüfteln.

This has some nice and new logic. As a mathematician familiar with "Egyptian fractions" there were things I spotted straight away which might take a bit of working out if you don't already know them. So 2* for me but probably 3* if you have to work out the maths. Neat puzzle.

It took a bit of number crunching to figure out which numbers could go with which other numbers to create integers. Box 8 really forces you to think about that. Very enjoyable puzzle! 3/5 difficulty sounds right.

Nice puzzle. I needed a bit to understand which constellations work but after that it was easy.
Difficulty: 2.5
