If you liked Einstein’s riddle, we offer you five puzzles with the same solution principle. Zebra puzzles are a kind of logic problem composed similarly to the riddle of an outstanding physicist
Puzzle #1. What do the Potters dream of?
Let’s meet the Potters: Mummy, Daddy, their son Peter, a schoolboy, and his younger sister Betty. There is also Aunt Polly, who often visits them. Each family member has his or her hobbies, favorite desserts, and dreams!
Conditions of the puzzle:
- Mummy Potter attends yoga classes on Mondays and Thursdays.
- A person loving ice cream dreams of visiting Paris.

- The Potters have three money boxes for their dreams at their home: one for a trip to the sea, one for a ticket to the Swan Lake ballet, one for a new album for the collection of coins.
- Aunt Polly has a sewing machine and a collection of sewing materials at home. She made a ballet suit for Betty for her classes.
- Peter often goes fishing with his dad, but he quickly becomes bored of it and begins to walk down the shore looking for rare coins for his collection.

Read these statements, fill in the table and say who likes the Napoleon cake and who dreams of going to Paris.
Show answer
Answer: Daddy loves Napoleon cake, and Aunt Polly dreams of visiting Paris.
These are the so-called Zebra puzzles. According to the legend, the famous physicist Albert Einstein, known as the Nobel prize winner and author of the theory of relativity, came up with such a quiz when he was a child. As a rule, such puzzles should be solved in mind, but, of course, it would be easier for children to fill in a table that will show the way to the solution.
Riddle #2. One Evening
Once Donald Smith came to visit his schoolmate Bill Simpson to do their homework together and learn William Shakespeare’s sonnets. When he entered Simpsons’ apartment, he could see five pairs of shoes: sandals, office shoes, lace-up boots, and two pairs of sneakers.
Try to guess which room each of the Simpsons’ family members (Bill, Mummy, Daddy, Granny, and Bill’s sister Melanie) is in, what they do, and what kind of shoes each of them was wearing outdoors before coming home.
These statements can help you.
Conditions of the puzzle:
- Daddy is in the kitchen alone.

Puzzle #3. A Bowling Game
Toadigy, Ducktor Hillary, Professor-r-r Roary, Zeebrain, and HaliLeo were playing ten-pin bowling. They had bowling balls of four colors — yellow, green, red, and blue.
Guess what order they have made their moves, what color balls they have chosen, how many strikes they have hit, and how many misses they have made.
A strike is a successful move in a bowling game in which a player knocks down all the pins in one hit.
Conditions of the puzzle:
- HaliLeo began the game and collected 10 strikes, which is more than others.
- The number of HaliLeo’s misses was similar to his order number in the game.
- Balls of all colors have been used.
- HaliLeo and Zeebrain have chosen balls of the same color.
- Ducktor Hillary has chosen the ball of the color, which can be reached by mixing colors of balls of the second and third players.
- Toadigy was playing after Professor-r-r Roary. He has chosen a yellow ball and beaten two times fewer strikes than HaliLeo.
- Professor-r-r Roary wasn’t’ first. He had no misses, beating the pits with a blue ball.
- Ducktor Hillary played last, having six misses and twice fewer strikes.
- Professor-r-r Roary had the same amount of strikes and misses.
- Toadigy had one fewer misses than strikes. Zeebrain had the same amount of misses.
- Zeebrain had one fewer strike than Toadigy and one more strike than Ducktor Hillary.
- HaliLeo and Zeebrain entered the game before and after Toadigy correspondingly.
1. What color were HaliLeo and Zeebrain’s balls?
2. If you answer the quiz properly, you will see some specific order of the players. Which one?
Show answer
Answer: HaliLeo and Zeebrain were playing red balls. HaliLeo had 1 miss, and Zeebrain had 4 strikes. If the table is filled properly, then the names of the characters will be in the following order.
