**Standard Sudoku, Cages, and Parity Lines; Mod4 Lines** - Standard sudoku: The digits 1 through 9 appear in every row, column, and box. - Parity Lines: Digits along blue parity lines alternate odd/even. - Mod4 Lines: Any three adjacent cells along rose Mod4 lines must contain digits with three different remainders when divided by 4. - Cages: Digits in cages cannot repeat and must sum to the value shown in the upper left corner of the cage. The lines in boxes 1, 3, 5, 7, and 9 are rose Mod4 Lines. The lines in boxes 2, 4, 6, and 8 are blue Parity Lines.
