This seems like a regular sequence of numbers, except it’s not! Can you find an error?

Puzzles are proven to help improve our brain function, logical thinking, and concentration! We love finding challenging puzzles for you to try out so this is a new series of brainteasers for you! What are you waiting for, give it a go!

Can you solve this puzzle?

This one isn’t so hard.

This may look like a simple number sequence to you but it actually has some numbers missing.

Give yourself ten seconds to spot them.

It’s left so many people stumped.

People love scratching the heads over finding the right solution to a puzzle. What about finding one here?

This task requires speed and attention. Looking at every single number is not as fun.

Do we trust what we see the first time or do we need to check again?

It’s so interesting how our brain processes information. We tend to skip numbers believing they are all there.

But, can you spot what numbers are missing?








The answer is that numbers 11 and 32 are missing. Did you spot this in under ten seconds?


There’s a multi-digit number hiding in this picture – can you see which one it is?

Find the number hidden inside the picture

Most times, it’s all about getting your eyes and brain to work together. It’s only when you get serious about it, that you can find out those little details that will lead you to the solution.

Like with the optical illusion below, for example, that I brought to test you today. I recently shared it with four of my colleagues, but only one got it correctly right away. In other words, it’s difficult.

I had to sit down and concentrate; it took a while before I found the answer. It should be said, however, that this isn’t about either intelligence or vision ability. Sure, it’s clearer if you have reduced vision, but otherwise, it should be balanced.

Try to find the number hidden in this black-and-white image!

Will you succeed?

If you can’t see it, we can reveal is a double-digit, then you can try to look again from a little further away.

Look from different directions

Then it becomes much easier.

Otherwise, it may also help to check from different directions.

Is it easier now?






Here is the answer!

We hope you are ready!

The hidden number in the picture is 17!

Did you find it?
