Normal Sudoku rules apply. German Whispers- Numbers on green lines are at least 5 apart from their neighbors on the line. Renban- Numbers on a purple line are a consecutive set of non-repeating numbers, in any order. Numbers with a black dot between them are in a ratio of 2:1. Numbers with a white dot between them are consecutive. Numbers with an X between them sum to 10. Not all dots and X are given. Cells with a gray square are even.
