Can you find the thief who stole the world’s rarest exotic fish from the city’s aquarium? There are 5 houses, each with a resident of a different nationality, each drinking a different beverage, and smoking a different type of cigar. Each house’s interior walls are of a different color, and finally, each house contains a different animal, one of which is our fish.

Look at the clues below, and check out the video at the bottom of this post for the answer!

1- The Brit lives in the house with red walls.
2- The Swede has a dog.
3- The Dane drinks tea.
4- The house with green walls is directly to the left of the house with white walls.
5- The owner of the house with green walls drinks coffee.
6- The person who smokes Pall Mall cigars owns a bird.

Before he turned physics upside down, a young Albert Einstein supposedly showed off his genius by devising a complex riddle involving a stolen exotic fish and a long list of suspects. Can you resist tackling a brain teaser written by one of the smartest people in history? Dan Van der Vieren shows how.
