Prime Management
(Published on 21. December 2023, 16:43 by Dr Logic)
I'm not sure on the difficulty on this one, but I've put 4 stars as it can potentially be quite difficult.
Rules:
- Normal sudoku rules nearly apply: Place the digits 0-8 in each row, column and 3x3 box.
- Prime Lines - Digits along a pink line must sum to the product of the prime numbers along that line. Digits may repeat along a line if allowed by other rules.(A product can consist of 1 number)
- Anti-knight- Cells separated by a knights move cannot contain the same digits.
- Kropki dots - Cells separated by a black dot must be in a 1:2 ratio. Cells separated by a white dot must be consecutive (not all dots are given).
- No two lines may have the same sum.

Solution code: Row 1 followed by column 1 (18 digits)

This is quite stunning! Believe it or not, I found the hardest part is the knight moves in this puzzle! The Prime Lines are pretty straight forward though.

If a prime number is repeated on the line, would it be multiplied twice? E.g. if the line has 2235, is the product 30 or 60?
-------------
Hi, if a prime is repeated on a line, the repeated prime(s) also count towards the total. So 2235 would be 60

Produkt? kann ein Produkt auch nur aus 1 Primzahl bestehen?
-----------------------
Ja, das hätte in den Regeln klargestellt werden sollen. Entschuldigung
