What is the name of einstein's riddle

Can you solve Einstein's riddles?

Albert Einstein (1879 - 1955) was probably the most famous theoretical physicist who ever lived. He was born in Ulm in what is now Baden-Württemberg, grew up mainly in Munich and studied in Zurich, Switzerland. We owe to him the general and specific theories of relativity, as well as the first idea of ​​gravitational waves and much more. He had a Nobel Prize in Physics, was a professor at the most prestigious universities in the world, most recently at Princeton University in the USA. But apart from that, he also campaigned for world peace and international understanding. Albert Einstein was Jewish and therefore emigrated to America after 1933 because Europe had become too dangerous.

Aside from all the great works in theoretical physics, he supposedly also created a puzzle that can keep you busy to this day. You can grit your teeth at it, it is at least as difficult as the solution in an escape room.

By the way, did you already know that Albert Einstein actually flew from high school? Not because of a lack of intelligence, but because of a lack of discipline. The otherwise concentrated thinker was quite a rebel in his youth who had little interest in the non-scientific part of school education. Later, in Switzerland, he did his Matura (Abitur), of course with top grades - whatever else.

The idea

It remains controversial whether Einstein actually came up with this riddle for adults, or whether it was someone else. In any case, it is associated with the famous physicist. It is even said that he thought it up as a child, not as an adult. Others claim that he invented it as a professor because too many students wanted him as a mentor and thus he sorted out the majority of applicants. It is also said that only 2% of all people who are confronted with this puzzle can actually solve it.

Whether it is from Einstein's pen or not, it is a puzzle quiz that definitely suits the taste of a theoretical physician. It is very difficult to solve and requires a lot of thought and trying different approaches.

This puzzle is best suited for long periods in a group with friends. With New Year's Eve coming up soon, this would be the perfect opportunity! If you don't know what to do between the sumptuous dinner and midnight - just unpack the riddle and start puzzling.

The riddle

Attention everyone, here comes the task:

There is a row of five houses that have been painted five different colors. A person of a different nationality lives in each house. Each of the homeowners drinks a specific drink, smokes a specific brand of cigars, and has a specific pet. But none of the owners drinks the same drink, smokes the same brand of cigars, or has the same type of pet.


  1. The Brit lives in the yellow house.

  2. The Swede has dogs.

  3. The Dane is drinking tea.

  4. The green house is directly to the left of the white house.

  5. The owner of the green house is drinking coffee.

  6. The owner, who smokes Pall Mall, raises birds.

  7. The owner of the yellow house smokes Dunhill.

  8. The owner who lives in the middle drinks milk.

  9. The Norwegian lives in the first house.

  10. The owner who smokes blends lives next to the owner who has cats.

  11. The horse owner lives next to the one who smokes Dunhill.

  12. The owner who smokes Bluemasters drinks beer.

  13. The German smokes Prince.

  14. The Norwegian lives next to the blue house.

  15. The owner who smokes blends lives next to the one who drinks water.

And here comes the crucial question: who owns fish?

The solution 

There is a video on Youtube for the best explanation of how to solve this puzzle.

First you should create a table, the columns will show the houses from left to right and the rows will show all information, i.e. color, nationality, animal, drink, cigar brand.

A little tip: if you use paper, make sure that the table becomes large, otherwise you may run out of space in the fields (see next paragraph). Now you can fill in what you know, that the first house houses a Norwegian, that milk is drunk in the middle house and that the second house (= next to the Norwegian) is blue.

This way you can fill in many of the fields. The approach of this puzzle is the same as in the well-known Japanese puzzle Sudoku, because each possibility can only occur once. If there is more than one possibility for a field, just do it as with Sudoku and write all of the possibilities in small letters and in pencil in the corner of the field. This allows you to use the exclusion method, because sometimes an animal or drink only appears in a single field.

Don't despair

Don't just think "oh dear, only 2% can solve this puzzle, we'll never make it!" We don't even need to start and try, it won't work anyway. "

You will quickly find that Einstein's puzzle works just like an escape room: you don't have to be incredibly intelligent or a scientist in a particular field to come up with the solution. All it takes is the right approach and a little patience.

It takes a great group that can work well together, pen and paper (or Excel), and a little patience. You have the whole of New Year's Eve to approach the solution. So take this time and enjoy the puzzle!

That is exactly the difference between the alleged 98% who do not come up with the solution and the 2% who make it.

Have you found the solution and do you want more of it? There are tons of websites where you can find hundreds of these puzzles.

If you feel like a little more action, you can take your group to the Escape Room. Here you are given a whole bunch of puzzles for adults and you have to find the solution within an hour. You will not just sit around a table and work on a table, but your whole effort will be asked.

At Exit the Room there is an escape game that runs just like Einstein's logic game. Mind Boggling is about the fact that for mysterious reasons you are suddenly in the brain of a genius. To get out of it, it takes a lot of creativity, logic and someone who holds the group together well. The task will only be solvable if your group works its way through both halves of the brain and connects the creative side with the logical. That sounds complicated at first, but here, too, the way to a solution can be a very simple one if you only approach the matter systematically and never lose track of things. Because sometimes the next clue or even the complete solution is right under your nose and you have simply overlooked it so far.
