Discontinuity

Title: Discontinuity

Rating: 1/5

The title comes from the overlapping regions in the center square.  Note that the number in the center is part of both the horizontal and the vertical regions through that square.

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.
