Title: Dark and Stormy
As the hardest mix puzzle yet posted, you may feel the need to make yourself the titular drink. If so, it's dark rum and ginger beer on the rocks, garnished with lime.
The official rules:
- The digits 1 through 9 appear in each row and each column exactly once.
- Digits in each shaded region must add to the indicated sum (denoted by +) or multiply to the indicated product (denoted by *).
- Squares with multiple colors contain a number that’s used in the sum/product for adjacent regions of each of those colors.
- Remember: numbers can repeat within a shaded region if that repetition doesn't violate the first rule.
