Bread and Butter (Killer + Entropic Lines)
(Published on 18. October 2025, 10:00 by sujoyku)
It combines two of my all-time favourite constraints: Entropic Lines and Killer cages. I am thanking Calvinball and NEWS for testing and wish you joyful solving!
Rules:
- Normal sudoku rules apply, i.e. each row, column, and 3x3 region has to contain the digits from 1 to 9 once each.
- Entropic Lines: Any three adjacent digits along a peach line must contain one low digit (1, 2, or 3), one medium digit (4, 5, or 6) and one high digit (7, 8, or 9).
- Killer cages: Digits in a cage must sum to the clue in the top left.
Here you can solve the puzzle online:
Shaded version: Solve on Sudokupad
Unshaded version: Solve on Sudokupad
Solution code: Row 5 from left to right (9 digits in total)

it was fun until i started on the middle row of boxes and got really confused and had to guess a cell to finish. Really good nonetheless!

If a 1* sudoku is still able to be so magnificent it's probably the work of Sujoyku. Thank you for another beautiful puzzle! <3
