Title: Lighten Up
Given the desire to have a puzzle where the colors steadily faded as one travels inward, there are lots of un-twisty regions. Hence the easier rating.
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.
