Today’s Sudoku combines the increasing numbers logic of a Thermo Sudoku with the addition logic of a Killer Sudoku. It isn’t that difficult but you still need to get used to working with both together. I could perhaps have put a thermometer figure with a sum on the corner, but chose this layout for 2 reasons – Its easier to draw the image this way, and the fact that it enables having just normal Killer cages too.
Rules – Follow regular Sudoku rules. Additionally, the number at the top left of a cage gives the sum of the numbers within the cage. Numbers cannot repeat within a cage. Also, in cages with a shaded cell, the numbers increase from the shaded cell to the ends of the cage.
