I’m kinda into logic and puzzles. So I found this puzzle on the internet, and since it was harder to solve than what I first realized, I thought I’d run through the process I used to solve it. I believe the puzzle to be created by Jerome R. Breitenbach and can be found in it’s original state on this page.

To begin with, here’s the premise:

In a particular apartment complex, five different people–Arnie, Bernice, Chip, Daniel, and Elizabeth–live in five different apartments–A, B, C, D, and E–that are contiguous and ordered alphabetically. Each person owns a different pet–aardvark, badger, crocodile, dolphin, or egret. Each person prefers a different drink–ale, beer, coffee, dry martini, or espresso. And, each person participates in a different sport–arm wrestling, baseball, car racing, diving, or equestrian. Also:

  • Each person lives next-door to a person having a gender that is different than their own.
  • For each person, the first letter of their name, apartment, pet, drink, and sport are all different.
  • For each person, the number of letters (spaces not included) in their name, apartment, pet, drink, and sport are all different.

Question: Who participates in the sport of equestrian, and what does the owner of the dolphin drink?

Give it a try yourself, and see if you come up with the same answer as me. When you’re ready, take a look at my solution.

Let’s begin walking through the solution…
