The brief
Normal sudoku rules apply.
Digits in cages do not repeat, and must sum to the given total.
Along SLOW thermometers, digits either stay the same or increase as they move away from the bulb.
A digit in a blue circle indicates how many circles contain that digit.
Digits in white circles must appear in cells touching that circle.
