This week offers another product puzzle whose title is inspired by blocks.

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.

For a change of pace, here's an alternate puzzle.  Brainfreeze Puzzles recently released a book with 10 X 10 puzzles with pentomino blocks.  Having seen test runs of such puzzles a couple of years prior to that, I decided to see what that style of puzzle would look like with overlapping regions in a standard 9 X 9 board.  I created four such puzzles; this is the first.



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 fairly easy product puzzle this week, one where choosing the right point to start causes the rest of the puzzle to topple quickly afterwards.

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.
