Illusions that play with your mind and see how well you can see details are called optical illusions. Scientists use them to learn more about how our brains process what we see.
Also, these games help you think more clearly and come up with new ideas. You can remember things better and solve problems better if you do these things often.
There are a bunch of apples grouped in a grid in the picture above.
At first glance, all of the apples look the same, but they're not. There is one apple that is not like the others. How long does it take you to find that apple?
This short optical illusion task will test how well you can see things. Now is your time!
Carefully look at the picture. Have you come across a strange apple? People who are very good at noticing things can find the odd apple faster than other readers.
Take one last look at the picture before time runs out. And... It's time to go. How many of you have found the apple in the hat within the time limit?
The people who did deserve praise; you have the best eyesight.
If you are still looking for the answer, you can stop looking and read the answer.
