Title: What Do You Mean?
The official rules:
- The digits 1 through 9 appear in each row and each column exactly once.
- Digits in each shaded region must multiply to the indicated product.
- Squares with multiple colors contain a number that’s used in the product for adjacent regions of each of those colors.
- Remember: numbers can repeat within a shaded region if that doesn't violate the first rule.
- The center square is the geometric mean of the four squares immediately diagonal to it.
