Bob Webber

Title: Bob Webber
Rating: 3/5

In conjunction with the April Problem of the Month, I'm posting this puzzle that celebrates my colleague Bob Webber's 43rd and final year at Longwood.  He had an extraordinary influence on many lives, including mine.  He is truly irreplaceable.

The official rules:

  • The positive integer factors of 2015 (of which there are 8) and the number 43 (his years of Longwood service) appear in each row, each column, and each 3X3 grid 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.
