Horseshoe #1
(Published on 25. November 2025, 16:07 by AParliamentofOwls)
Normal Sudoku Rules apply. Every row, column and marked region in the puzzle must contain the digits 1-9 exactly once.
Additional Rules:
Global Entropy: Divide the digits 1-9 into low(123), middle(456), and high(789) digits. Every 2x2 cell group in the puzzle must contain at least one digit of each group.
Kropki: White dots connect consecutive cells, black dots connect cells in a ratio of 1:2. Not all dots are given.
Cage Kropki:Kropki dots between two killer cages refer to the cage sums instead of the individual digit.
Sandwich Sums:The number next to a row or column is the sum of all digits that are located between the digits 1 and 9 in that row or column.
Killer Cages: Digits in cages sum to the number in the corner of the cage (if given) and can't repeat within a cage.
Solution code: column 5, top to bottom

Added Killer Constraint

It might be worth mentioning that the cages cannot have repeated digits in them? I couldn't make any progress without that assumption.
Oops sorry, I forgot to add the killer constraint. Will add it momentarily!

entropy is one of my favourite and it's done really well here, thank you! there's a lot of things to track, but i think it's approachable. perfect 3
