Title: Zurracapote

Rating: 3/5

This is a drink I hadn't heard of before I started creating mix puzzles. This Spanish drink is made with red wine, fruits (in the case of the puzzle colors, peaches and lemon), cinnamon, and sugar.
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.
 Remember: numbers can repeat within a shaded region if that repetition doesn't violate the first rule.
The weather's been rainy where I live for much of the last week, so this product puzzle will fit nicely. The most challenging part of it involves the regions moving between more than two rows or columns.

In the continued vein of how things get named, I'm hoping you'll be able to cheer about the name for this one. There are a few areas to be careful of, though. Make sure to check out the rules below.

 Squares with multiple colors contain a number

 Cells
at the following positions belong to the regions that go horizontally and vertically
through that cell: (2,2), (2,8), (8,2), (8,8), (4,4), (4,6), (6,4), (6,6). The (light purple) color of these cells is the RGBaverage of
the colors from the horizontal and vertical regions that intersect there.

Title: Prorus

Rating: 3/5

Not your typical product puzzle this week. The board is what I call a "toral board," so named because the board is meant to be viewed not as a big square, but as what's called a fundamental region. In this case, imagine folding the sides of the square together to get a cylinder. Then fold the ends of the cylinder together, and you get what's called a torus (a donut, if you will). Those associations (between left and right, between top and bottom, and, hence, between all corners) are reflected in the rules below.

 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.
