The brief
Normal Sudoku Rules apply. German Whispers (Green): Adjacent digits must differ by at least 5. Renban (purple): Form a set of consecutive digits in any order. Region Sum (blue): Digits along each region sum line must sum to N in each 3x3 the line passes through. N can be different for different lines. Nabner (gold): No digits along a nabner line can be consecutive. (e.g, 135 is allowed but 192 is not, because 1 and 2 are consecutive) Thermometer (grey): Digits along a thermometer must strictly increase starting at the bulb (the grey circle) Ratio (black dot): Cells separated by a black dot must be in a 1:2 ratio. Difference (white dot): Cells separated by a white dot must be consecutive.
