Title: Amends

Rating: 1/5

If the first of these was challenging, this second of the four "pentoku" puzzles I created should engender some good will. It's one of the easiest puzzles I've created.
The official rules:
 The digits 1, 2, 3, 4, and 5 appear in the above puzzle.
 Each shaded
region contains exactly one of each of the digits 1 through 5.
 No row or column can contain more than two
appearances of any of the digits 1, 2, 3, 4, 5.
 Squares with multiple colors contain a number
that’s used in both of the associated adjacent regions.

Rating: 3/5

A classic drink headlines this week's mix puzzle. Typical ingredients are gin, lemon juice, and sugar syrup, with a maraschino cherry as garnish.
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.

This week's product puzzle was modeled to more clearly exhibit the symmetry of construction. Each of these puzzles has not just 180 degree symmetry, but a 90 degree symmetry, with colors consistently shifting as the puzzle rotates.
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.
Don't be tempted to look at the sky. Keep your eyes on the puzzle.
