(Published on 27. December 2025, 19:05 by Enchanter73)
Hello everyone, I am relatively new to the sudoku world and this is the first time I tried creating a puzzle. I am open to any criticism. I hope you enjoy it!
RULES:
Normal 6x6 sudoku rules apply: Place the digits 1-6 once each in every row, column and 2x3 box.
Global entropy: Each 2x2 area in the grid must contain at least one digit from each of the three entropic sets: {1,2}, {3,4}, {5,6}.
Renban: Pink lines must contain a set of consecutive, non-repeating digits in any order.
Little Killer: Digits along the indicated diagonal must sum to the given total. Digits may repeat if allowed by other rules.
