Cloning pink elephants
(Published on 30. July 2024, 20:36 by CraftyRaf)
Normal Sudoku rules apply: Fill the grid with digits 1-6, once each in every row, column, and 2x3 box.
Clones: There are four 2x2 clones in the grid. Each clone must have identical digits in the same positions. Rotations and reflections are not allowed. The location of one clone is given (in grey); the locations of the other 3 clones must be determined.
Line Sum: Digits in cells that are part of a clone and lie on an orange line must sum to 10, while digits in cells that are NOT part of a clone and lie on an orange line must sum to 37.
Pink elephants: Digits in cells that share an edge and are separated by a pink elephant must sum to 7. All pink elephants are given.

Are you sure this has a unique solution? I'm pretty positive I've found at least 1 solution that's not yours :(

CraftyRaf: You are right, I made a mistake while checking uniqueness after dropping the last constraint. This puzzle should have a unique solution now, I'm sorry for your lost time!

Edit 2024/07/30 21:11 - The constraint that I removed wasn't necessary to solve the puzzle! I also changed the title and the link to sudokupad because of that.
Edit 2024/07/30 22:26 - I needed the last constraint after all... Thanks 'cybers' for pointing that out! I changed to the original title and link again.
