Sudoku 10 in Black and White
(Published on 25. November 2025, 20:21 by juggler)
LATIN ELLIPSE - In the center of each large grey square, place a digit from 1-7. Squares can't have the same digit if their rows or columns overlap (i.e. if some horizontal or vertical line could intersect both squares).
KROPKI - Squares connected by a white ェ have consecutive values. Squares connected by a black ェ have values in a 1:2 ratio.
Solution code: Digits down the center of the tallest column (5 digits)

Wow, not so hard but I really loved this one! When I finished the solve, I paid attention to the title and felt guilty for using colors.. Thanks for this chef-d'oeuvre!

Truly elegant in both the aesthetics and the underlying logic. I very much enjoyed!

That was some 4* coloring, for a 5* hotel of a puzzle. I love this collection, thank you for putting so much care into these puzzles!

Sorry, master Mondrian. I destroyed your beautiful artwork - and colored it!
Thank you, Michael, for another piece of your puzzle-art with this art-puzzle.

Really enjoyed this one. Was tough for me to start but once I wrapped my head around it was very enjoyable. Solution code is unintuitive though.

Fascinating concept, really enjoyed this, thank you. Didn't immediately understand the solution code, maybe "the top 3, and bottom 2 digits in the tallest column"?
