Chameleon Pentominoes

(Published on 16. August 2024, 05:00 by Will Power)

PENTOMINO CONJECTURE- After three years of trying, it is my conjecture that a Sudoku grid cannot be filled with 16 pentomino killer cages, all of value 25 (plus one single cell of value 5), where duplicate pentomino shapes (including reflections and rotations) always have the same numbers, and numbers do not repeat in cages. I encourage any setters to try to complete my quest. I have created the next best thing: Normal Sudoku rules apply. CHAMELEON KILLER CAGES(+)- Numbers in cages sum to 25. Numbers do not repeat in cages. Killer cages highlighted the same color have the same set of numbers in them (regardless of shape). Difficult mode has no colors. LITTLE KILLER SUMS- Numbers outside the grid are the sum of the indicated diagonal. KROPKI PAIRS- Numbers with a black dot between them are in a ratio of 2:1. Numbers with a white dot between them are consecutive. Where there is a conflict, black dots are shown. All possible dots are given BETWEEN DIGITS WITHIN THE SAME CAGE as one another. No negative restriction between cells of different cages.

I started the easy one but didn't use the colors at all. Still it seemed easy enough. Nice work

I rushed and had to restart and go a bit more carefully - a nice puzzle!

Nice and very easy - even without the colors. I wonder if you really need ANY constraints for the kropki… Thank you for creating and sharing.

@Franjo Hello, and thank you for playing and commenting. When using certain rules, the community expects secondary comments. For Kropki dots, the community demands that the setter declare if all dots were given or not. I have received negative comments and ratings when I omitted this detail. In this case, although you do not need to know that all dots were given in order to solve, stating that they were not given might throw someone off who is looking for that(those) stray pair(s) that is(are) missing their dot. Peace to you. -Will Power

Nice puzzle. I would only give it 1 star though, because you don't have to make any strange deductions.
