Modernista

Title: Modernista

Rating: 3/5

The final modular puzzle is named after a drink made from gin, dark rum, lemon juice, absinthe, orange bitters, and a maraschino cherry. 


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 (denoted by +) or multiply to the indicated product (denoted by *)--both mod 9.   
• Squares with multiple colors contain a number that’s used in the sum/product for adjacent regions of each of those colors.  
• Remember: numbers can repeat within a shaded region if that repetition doesn't violate the first rule.
