Turn, Turn, Turn

Title: Turn, Turn, Turn

Rating: 2/5

The rotational symmetry of these puzzles lends them, as has been seen before, a certain windmill-ian aspect.  So too here.  But more than that, the colors were chosen to represent each of the seasons.

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.
