The brief
**Standard Sudoku, Modular Lines, Thermometers, Ratio Pairs** Normal sudoku rules apply. Modular lines: Any set of three adjacent digits along a modular line has three different remainders when divided by 3. Thermometers: Digits along a thermometer must strictly increase from bulb to tip. Digits along the thermometer do not have to be consecutive. Kropki pairs: Digits separated by a black dot are in a 1:2 ratio. Not all possible dots are shown.
