Before he turned physics upside down, a young Albert Einstein supposedly showed off his genius by devising a complex riddle involving this list of clues.
Can you resist tackling a brain teaser written by one of the smartest people in history? Let's give it a shot.
The world's rarest fish has been stolen from the city aquarium. The police have followed the scent to a street with five identical looking houses.
But they can't search all the houses at once, and if they pick the wrong one, the thief will know they're on his trail.
It's up to you, the city's best detective, to solve the case. When you arrive on the scene, the police tell you what they know.
One: each house's owner is of a different nationality, drinks a different beverage, and smokes a different type of cigar.
Two: each house's interior walls are painted a different color.
Three: each house contains a different animal, one of which is the fish.
After a few hours of expert sleuthing, you gather some clues. It may look like a lot of information.
But there's a clear logical path to the solution. Solving the puzzle will be a lot like Sudoku.
