Normal sudoku rules apply. Any two cells separated by a king's move (in chess) cannot contain the same digit. Entropic lines: each set of three sequential cells along a peach line must contain a low digit (1, 2 or 3), a middle digit (4, 5 or 6), and a high digit (7, 8 or 9). Kropki: digits separated by a white dot are consecutive; digits separated by a black dot are in an 1:2 ratio (i.e. one digit is double the other). Parity lines: Along a red line, adjacent digits must alternate between odd and even.
