Copycat Confusion
(Published on 19. August 2024, 18:03 by Phistomefel)
Here are the exact rules of this puzzle:
- Normal Sudoku rules apply.
- Divide the four lines in the grid into two pairs. The lines in a pair are copycats of each other, i.e. they have the same composition of digits. E.g. if one line has two 3s, five 4s and a 9, then the other one also has two 3s, five 4s and a 9. The order of the digits is not necessarily the same on the two lines.
- The two lines in the grid with a circle on one end are an average arrow and a thermometer. The two lines without a circle are a region sum line and a german whispers line. The solver has to find out which line obeys to which rule.
- Average Arrow: The digit in the circle is the average (exact, not rounded) of the digits on the line.
- Thermometer: The digits have to increase along the thermometer, starting from its bulb.
- Region Sum Line: The line is cut into multiple segments by the box borders, each summing to the same number.
- German Whisper: Two neighboring digits have a difference of 5 or more.
Solution code: 4th row

Excellent construction. Very hard to determine which pairs are connected but it flowed very smoothly once the lines had been paired up. Thank you.

Not as hard as expected - 3 stars from me. The break-in was lovely. The trickiest part (for me) came later when I had to choose the right one from three options… Thank you so much for sharing another masterpiece.

Amazing idea and execution! The Copycat constraint produces new logic.
