Classic rules with a parity twist and with a narrow solving path. Have fun!
Normal Sudoku rules apply.
Opposite Parity Clues: On all clues (German Whisper, Renban, Kropki), any two adjacent digits (orthogonally or diagonally, as connected by the clue) must have opposite parity (one odd and one even).
Parity Switcher Cells: Each row, column, and box contains exactly one parity switcher cell. In such a cell, the digit is treated as having the opposite parity to its actual value (odd is treated as even, and even as odd).
German Whisper: Adjacent digits on a green line must differ by at least 5.
Renban: Digits on a purple line must form a set of consecutive digits in any order.
Black Kropki: Digits separated by a black dot must be in a 1:2 ratio.
