Standard TomTom Rules: Insert a number from the indicated set of numbers into each cell so that no number repeats in any row or column. Also, the number in the upper-left corner of each bold cage indicates the value of a mathematical operation (addition, subtraction, multiplication, division) applied successively to all numbers in the cage, starting with the largest number for subtraction and division (e.g. 1,2,4 with subtraction is a 1- clue as 4-2-1 = 1). The operation may or may not be given in the cage, but at least one of the four operations must apply. Numbers can repeat within a cage.

For automatic solution checking, the numbers must be entered in green, blue, or red.
