Thermo Sudoku, also called Thermometer Sudoku, follows standard Sudoku rules: use 1 to 9 once in every row, column and 3-by-3 box. Along each thermometer, the digits must strictly increase from the round bulb toward the end. They can skip values; they do not have to be consecutive. We count the cells, including the bulb, and leave you an eight-second silent countdown to think. Then we explain why this particular nine-cell thermometer fixes all nine digits. Shorter thermometers can still skip values. The rest of the puzzle is yours to solve. Sudoku Today | Variant Rules 04 Original puzzle: Thermo Sudoku #66088 on sudoku.today.
