The brief
**Sudoku, Modular Lines, Whisper-5, Kropki** - Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Modular lines: Any set of three adjacent digits along a modular line has three different remainders when divided by 3. - Whisper-5 Lines: Adjacent digits along a Whisper-5 Line differ by at least 5. - Kropki pairs: Digits in cells separated by a black dot are in a 2:1 ratio. Digits in cells separated by a white dot are consecutive. The outline of the ghost is a modular line. The word "Boo!" is formed of Whisper-5 Lines.
