Amends

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.

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.

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.

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.

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.

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.

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.
  • 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 RGB-average of the colors from the horizontal and vertical regions that intersect there. 
  • Remember: numbers can repeat within a shaded region if that doesn't violate the first rule.
