The regular semester has started again.  In celebration of that, enjoy this apĂ©ritif, made from gin, apricot brandy, and orange juice.  It's then traditionally shaken over ice.  

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.

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.
