Optical illusions and puzzles are not only incredibly fun but also come with various added benefits.

Besides helping you have a good time with your friends and family, optical quizzes can also boost your cognitive abilities and help you improve your eyesight and perception.

In today’s challenge, you will be confronted with two optical challenges. If you pass them both, you win! Let’s get started.

Your first task is to find out which of the three lines seen above is the longest. They might look similar, but which one is longer than the rest?

To find out the correct answer, you better zoom in and focus real hard.

Here’s another useful hint. To solve the puzzle, try covering the arrows at the ends of the lines with your fingers. You’ll see why that can help soon enough!

So, what’s your final answer? Is it line number 3? Wrong! Line number 2? Wrong again!

As it happens, all three lines have the same length. The optical illusion created by those arrows, however, sure makes it look as if the third line was longer than the rest.

Now that you have an idea of just how tricky these puzzles are, here comes another optical challenge for you to conquer.

This time, your task is to figure out how many faces are hiding in the image below. Keep in mind that you have to take all variations into account!

Have you completed the count yet? How many faces did you spot?

The first two faces are quite clear. But that’s not all there is to this puzzle. What if we told you there were actually four faces somewhere in there?

Take another look and give it your best shot before scrolling down to reveal the answer!
