Cognitive puzzles have always intrigued and challenged our minds, pushing us to think outside the box. Today, we have an interesting brain teaser featuring fried eggs with an unknown number in one corner. The big question is: What number should replace the question mark?
At first glance, this puzzle might seem straightforward, but many people struggle to find the correct answer. Let’s break it down step by step, analyze common mistakes, and finally arrive at the right solution.
Try to Solve It First!

Before we dive into the solution, take a moment to analyze the image. Each fried egg pair or grouping has a number next to it, except for the last one. Your challenge is to figure out the pattern behind these numbers and determine the missing value.
So, what’s your answer? 12? 24? Something else? Let’s see if you’re right.
Common Mistakes People Make
Puzzles like this often trick people into seeing patterns that don’t actually exist or missing key details. Here are some common mistakes:
- Assuming the numbers represent the total number of yolks
Many people assume the number is simply the count of yolks in each grouping. However, if that were the case, the values would be 2, 3, 2, and 3—this doesn’t match the numbers given. - Thinking the numbers count the number of egg whites
Some might assume the numbers are based on the number of egg whites. However, we see cases where eggs are overlapping, making this unreliable. - Overcomplicating the pattern
Some puzzle solvers jump straight to complex mathematical operations before checking simpler patterns.
If you made one of these mistakes—don’t worry! Now let’s walk through the correct method to solve this.

Step-by-Step Solution: Finding the Pattern
Let’s examine the numbers given: 12, 23, and 22. Each number corresponds to a different grouping of eggs. But what do they mean?
Step 1: Count the Yolk Pairs and Their Positioning
Looking closely at each plate, we see that:
- 12 → Two yolks in one egg white.
- 23 → Three yolks in one egg white + two yolks in another egg white.
- 22 → Two yolks in each of two egg whites.
From this, we see that the numbers are NOT just counting yolks or egg whites alone.
Step 2: Understanding the Number Formation
Observing the pattern, the first digit of the number corresponds to the number of yolks in the first egg, and the second digit corresponds to the number of yolks in the second egg.
- 12 → (1 yolk in the first egg, 2 yolks in the second egg)
- 23 → (2 yolks in the first egg, 3 yolks in the second egg)
- 22 → (2 yolks in the first egg, 2 yolks in the second egg)
Step 3: Identifying the Last Number
Now, let’s apply this pattern to the final grouping, which contains 3 yolks in one egg white and no additional egg.
Following the same rule, the first digit is 3 (yolks in the first egg), and since there is no second egg, we assume the second digit is 1.
Thus, the missing number should be 13.
Final Answer: 13
After carefully analyzing the pattern, we conclude that the correct number to replace the question mark is 13. The first digit represents the number of yolks in the first egg, and the second digit represents the number of yolks in the second egg.
Did you get it right? If not, don’t worry! The key takeaway is to pay attention to patterns rather than just counting random elements.

You won’t believe what’s in this man’s house, it’s made from an old airplane!

The interior of this plane is truly breathtaking! 64-year-old Bruce Campell, a retired electrical engineer, has always had a remarkable flair for creativity. In his twenties, he took a leap of faith and invested $23,000 in a 10-acre plot of land near Hillsboro, Oregon, with a vision in mind.
He decided to build an extraordinary mansion out of an old airplane on this sprawling property. Stay tuned for the upcoming reveal of the interior! Scroll down to find out more.

Campbell has always enjoyed taking things apart and putting them back together into something new. He envisioned his property as a canvas for building a unique home, using a collection of decommissioned cargo planes. Although he thought he was developing a completely original concept, he later discovered that a similar creation already existed.
About two decades after he came up with his plan, Campbell learned of Joanne Ussery, a Mississippi hairdresser who had converted a Boeing 727 into her home. After a fire destroyed her previous residence, Ussery decided to rebuild it in the shape of an airplane and move it to a quiet riverfront. After some thought, Campbell decided to change his original plans.

He made significant changes in several aspects. Read on to learn more about Campbell’s plane whereabouts and see more photos. In 1999, Campbell invested a staggering $100,000 to purchase a Boeing 727 from Olympic Airways. Transporting the massive plane from Athens, Greece to his property in Oregon was a major challenge. Including transportation costs, the total expense for the plane was about $220,000.

However, Campbell felt that every penny spent on the jet was worth it. The aircraft is equipped with the bare necessities of life. Campbell kept the original toilet and some seats and also added a washing machine and sink.

Despite the spaciousness of the Boeing 727, Campbell doesn’t spend much time in his unconventional abode. His kitchen is equipped only with a microwave and a toaster, and he usually subsists on cereal and canned goods.

While living in an aircraft like Campbell may not be for everyone, we can’t help but admire his incredible achievement! Just take a look at this remarkable aircraft. Accomplishing such a feat must be immensely rewarding. Watch the video below to explore the entire interior of this extraordinary aircraft home:
