Normal sudoku rules apply. Digits connected by a black dot have a 2:1 ratio. Digits connected by a white dot are consecutive. Cells separated by a chess king’s move cannot contain the same digit. Cells separated by a chess queen’s move cannot contain the same digit, but this rule applies only to digits 3, 6 and 9. Any three consecutive digits along a peach line must include a digit from the set (1, 2, 3), a digit from the set (4, 5, 6) and a digit from the set (7, 8, 9). All peach lines of length three MUST contain the digits 3, 6 and 9 in some order.
