Dreamcatcher

Title: Dreamcatcher

Rating: 3/5

 

This puzzle evolved out of wanting to experiment with more than just rectangles/squares to denote regions.  The creation of the layout was challenging enough that future experimentation went in different directions.

The official rules:

• The digits 1 through 9 appear in each row and each column exactly once.
• Digits in each shaded region must add to the indicated sum.   
• Squares with multiple colors contain a number that’s used in the sum for adjacent regions of each of those colors.  
• Remember: numbers can repeat within a shaded region if that doesn't violate the first rule.
