The brief
• Normal Sudoku rules apply. • Whisper-4: Adjacent digits along an orange Whisper-4 line must differ by at least four. The thinner lines forming the wine glasses are Whisper-4 Lines. • Parity Lines: Digits along a red parity line alternate odd/even. The thicker lines at the top and bottom of the wine are Parity Lines. • Wine Drops (ratio pairs): Cells separated by a red wine drop are in a 2:1 ratio. The red shading of the wine is cosmetic only.
