This Week's Exciting Puzzle: The Dating Game

This puzzle appeared in Volume 80, Issue 6 (July 16, 1999) of mathNEWS.


Hypothetically, the Mathematics Society at U(W) was able to scrounge enough interested parties (not necessarily humans, but we'll let that go for now) to play the game. And at the end of the game, they had five couples (for our purposes, we will use male-female couples), which they sent to a date at the movies (thankfully air-conditioned!). As it happens (coincidentally of course), each couple went to see a different movie at a different theatre. Each couple also shared a different snack while watching the movie. Your task is to determine who dated whom, where they went, what they saw, and what they ate.


  1. Katrina did not go to either the Bookshelf or the Mustang Drive-In with her date.
  2. William's date wasn't Katrina.
  3. The couple who went to the Princess Cinema did not eat popcorn.
  4. The couple who saw South Park ate the licorice (which wasn't the snack shared by Charlotte and her date or by Ron and his date).
  5. The couple who saw Notting Hill didn't share nachos.
  6. Zeke and Dianne didn't share a sweet, sugary snack nor did the couple who saw Wild Wild West (which didn't include Ron).
  7. Mark and his date saw Tarzan.
  8. Susanne (whose date wasn't Mark) didn't have a chance to eat dinner beforehand, so she and her date munched on hot dogs.
  9. Amanda and her date, who saw An Ideal Husband, didn't eat the chocolate-covered raisins.
  10. The couple who went to King's College Square did not watch South Park.
