The brief
**Sudoku, Whispers-4, Consecutive Dots** - Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Whispers-4 Lines: Adjacent digits along a Whispers-4 line must differ by at least four. - Consecutive Dots: Digits in cells separated by a white dot are consecutive. Not all dots are necessarily given.
