Bloom

Title: Bloom

Rating: 2/5

It's been a little while since a sum puzzle has been semi-relaxing.  Let this one bring forth thoughts of a cool spring during the dog days of summer.

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.

Brandy Alexander

A classic drink, known to Feist fans, fans of Days of Wine and Roses, and others.  It's a mix of cognac, Crème de cacao, and fresh cream, garnished with nutmeg.

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 *).   
• Squares with multiple colors contain a number that’s used in the sum/product for adjacent regions of each of those colors.

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.

This is another toral board puzzle, to join the ranks of Prorus and Circuitry.  As a reminder about the alteration, check out the last rule below.

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.
• The board is a “toral board,” that is, cells at the end of one row are considered adjacent to those at the beginning of the same row; cells at the end of one column are considered adjacent to those at the beginning of the same column, and all corner cells are considered adjacent.

A mix of peach brandy, lime juice, passion fruit juice, and Fraise de Bois (strawberry-flavored) liqueur, this seems like the definition of "fruit-forward."

• Digits in each shaded region must add to the indicated sum (denoted by +) or multiply to the indicated product (denoted by *).   
• Squares with multiple colors contain a number that’s used in the sum/product for adjacent regions of each of those colors.
