The brief
Normal Sudoku rules apply. DUTCH WHISPERS- Numbers on red lines are at least 4 apart from their neighbors on the line. Numbers may repeat on red lines. RENBAN LINES- Numbers on purple lines are each a set of no-repeating, consecutive numbers, in any order. RENBAN+ LINES- Numbers on yellow lines are consecutive with their neighbors on the line, and do not repeat. KROPKI PAIRS- Numbers with a white dot between them are consecutive. Numbers with a black dot between them are in a ratio of 2:1. Not all possible dots are given. Numbers in cages sum to the number in the top left corner of the cage.
