Title: Storm
Rating: 3/5

The weather's been rainy where I live for much of the last week, so this product puzzle will fit nicely.  The most challenging part of it involves the regions moving between more than two rows or columns.

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.
