The brief
** Standard Sudoku, Kropki Pairs, Dutch Whispers, Entropic Lines** All lines are both Entropic AND Dutch Whispers - Standard sudoku rules apply: The digits 1 through 9 appear in every row, column, and box. - Ratio pairs: Digits separated by a black dot are in a 1:2 ratio. Not all dots are necessarily given. - Dutch Whispers: Adjacent digits along a Dutch Whispers line must differ by at least four. - Entropic Lines: Any set of three sequential cells along an entropic line must contain a low digit (123), a middle digit (456), and a high digit (789).
