The other day I noticed this article on Coudal Partners. The article concerns a classic brain teaser that may or may not have been created by Albert Einstein. Here’s the gist:
There are five houses in a row in different colors. In each house lives a person with a different nationality. The five owners drink a different drink, smoke a different brand of cigar and keep a different pet, one of which is a Walleye Pike.
The question is– who owns the fish?
So I decided to whip up this quick little grid to help me work through the questions’ hints. It seemed to be an easier way than trying to keep track of things on paper or in a text file. It doesn’t have any cool actions to it (it won’t tell you if you’re right; fields won’t highlight or anything), but it’s 100% free to use/remix so if anybody out there can improve on it, go ahead.
Update: Thanks to Coudal for linking to it!
