(Published on 15. November 2025, 15:02 by DubiousMobius)

This puzzle was created for Scojo's weekly setting prompt. This time the theme was Mad Fold-in puzzles. Big thanks to dangernoodle and aqjhs for testing the puzzle! All feedback is appreciated, and thanks for playing!

Rules:

Sudoku:Place the digits 1-9 once each in every row, column, and 3x3 box.

Evens: Cells with a grey square will contain an even digit.

Kropki Sum Line: Along a grey line, diamonds separate the line into segments. Each segment has a value equal to the sum of its digits. Segments separated by a white diamond have consecutive values. Segments separated by a black diamond have values in a 2:1 ratio. Digits may repeat within a segment.

Mad Fold-In: If the cells between the dashed columns are removed, all clues fold into valid clues in the resulting 4x9 grid.
