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, if other rules allow. RENBAN- Numbers on purple lines are each a set of non-repeating, consecutive numbers, in any order. THERMOMETER- Numbers on thermometers increase from the bulb end. KROPKI PAIRS- Numbers with white dots between them are consecutive. Numbers with black dots between them are in a ratio of 2:1. Not all possible dots are shown.
