Entropic Killer Dots / Entropische Killerpunkte
(Published on 7. January 2024, 16:14 by PDN777)
Normal sudoku rules apply. Digits in a cage must sum to the little number in the upper left, and may not repeat in the cage. Neighboring digits marked with a white Kropki dot are consecutive. Neighboring digits marked with a black Kropki dot have a 2 to 1 ratio. Not all dots are given. Any set of three sequential cells along a beige entropic line must contain a low digit, a middle digit, and a high digit. For a 9 x 9 grid, this means 1-3; 4-6; and 7-9. I think this puzzle is 1 star out of 5 for difficulty for many solvers -- it's a one-trick GAS, but I really like the trick. :-) As always, comments welcome. Thanks!

SPOILERS!!! @Suxamethonium This is precicely what I did too! And then of course you can colour in all the "low" digits along the line. Also, each box, row, and column of obviously needs three of each colour, and of course I wanted to make it look nice so I coloured everything

Nice puzzle! Quite liked how the black Kropki dots and the entropy lines worked together to disambiguate the puzzle.

Very fun as a newcomer to entropic lines :) 9:04 for me

Fun solve and fairly easy so long as you are familiar with entropy lines. Coloring helped me a lot.
** I'm glad u enjoyed!

Fun, thank you. I’m still doing just the one-star puzzles and it took me a half-hour.

this isn't GAS, because it requires knowledge of entropy PROCEDURES. however, "trick" is too strong, because it implies "user-developed" procedure.

Wondering which "trick" you might have in mind. I started straightforward by looking at the enthropies in the cages. Starting from there it was plain sailing, no tricks required. Perhaps it helped that I used colour code for low/middle/high to spot them more quickly. Great puzzle, which I enjoyed very much. Thanks for setting!
** Hi - well - I don't want to write in a spoiler, but basically, you crossed its path at the outset. It's pretty simple, but I'd never noticed it before.... ;-)
