Color Blur

Title: Color Blur
Rating: 2/5

One day my older daughter saw me trying (in vain) to come up with a name for this puzzle.  I had some version of writer's block--the kind least likely to matter, I suppose.  I decided to let her name this puzzle, and "Color Blur" is what she came up with.

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.
