The brief
Normal sudoku rules apply.
Along thermometers, digits must increase from the bulb end.
Digits along a blue line sum to the same value in each 3x3 box the line passes through. Crossing lines go straight and are counted as separate sums.
Adjacent digits along a green line must differ by at least 5.
Digits separated by a white dot must be consecutive. Not all dots are given.
Cells separated by a king's move cannot contain the same digit.
