Title: Central Office
This week's product puzzle was modeled to more clearly exhibit the symmetry of construction. Each of these puzzles has not just 180 degree symmetry, but a 90 degree symmetry, with colors consistently shifting as the puzzle rotates.
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.
