XV and Entropy
(Eingestellt am 22. Juli 2026, 19:28 Uhr von addie)
Antiknight and Antiking: Any two cells separated by a knight's or king’s move in chess cannot contain the same digit.
Nonconsecutive: Any two orthogonally adjacent cells cannot contain consecutive digits.
XV: Digits separated by an X sum to 10, those separated by a V sum to 5. Not all Xs and Vs are necessarily given.
Global Entropy: Every 2x2 box contains one low, medium, and high digit (123, 456, 789).
Lösungscode: Row 9

12 minute solve. It is pretty well known that Anti knight/king and non consecutive equals roping. To the north/south it is roping, and to the east west it is mod 3 in the first column, next mod 3 in second column, last mod 3 in last column - and that repeats to the next columns to the right (or vice versa roping/mod3 columns/rows). So if Box 1 column 1 is 258, and column 2 is 147, and column 3 is 369, then box two must follow - 258,147,369; and box three the same. And the Columns in column 1,2,3, are roping. Anyway lots of puzzles like this. I just tested the "v" clues for roping to either the east/west or north/south. Did not need global entropy to solve. Looks like a 4 star puzzle (currently) if you don't know this pattern. I gave it a 1 star for those who do. Thanks!
