The brief
- 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 teal modular line has three different remainders when divided by 3. - Dutch Whispers: Adjacent digits along an orange Dutch Whispers line must differ by at least four. - German Whispers: Adjacent digits along a green German Whispers line must differ by at least five. - Kropki dots: Digits in cells separated by a black dot are in a 2:1 ratio. Digits in cells separated by a white dot are consecutive. Not all dots are necessarily given.
