3 Mind-Blowing Lateral Thinking Puzzles

/, Self-Improvement, Self-Knowledge & Personality Tests/3 Mind-Blowing Lateral Thinking Puzzles

lateral thinking puzzlesHave you ever wondered if your mind is normal (i.e. average) or somehow different? Here are 3 lateral thinking tests. The answers are published below, but do not go immediately to read them! Think up your own answers first.



Here is the story of a young girl. At her mother’s funeral, she saw an unknown young man. He was charming, really the man of her dreams. She madly fell in love with him. After a couple of days the young girl killed her own sister…

Question: What motive did she have to do it?


Take at most 10 seconds to do this test, otherwise it will not work.

Find how many ‘f’s there are in the following text:

+ + + + + + + + + + + + + + + + + + + + + + + + + + +





+ + + + + + + + + + + + + + + + + + + + + + + + + + +


Do the following reasoning exercise, answering the questions one by one, without going to the next question if you have not answered the previous yet.

It is not necessary to write your answers.

How much is:

15 + 6 =

3 + 56 =

89 + 2 =

12 + 53 =

75 + 26 =

25 + 52 =

63 + 32 =

Yes, these are a bit more difficult but the exercise is really worth doing, so be patient:

123 + 5 =

Now think of a tool and a color!




She hoped that the young man would appear again at the funeral.

Explanation: If you gave the correct answer, you probably think like a psychopath.

The test was developed and used by a famous American psychologist to determine whether a person has murderous mentality. Several criminals who did the test correctly answered the question.

If you did not give the correct answer, it is good for you! If someone of your friends found it, keep away from him! 🙂


How many ‘f’s did you find? Three?

It is wrong, there are six!

If you don’t believe, go above and count them again!

Explanation: The mind cannot process the ‘OFs’. Awesome huh?

Anyone who manages to find six ‘f’s is a genius, those who find four or five are really rare, three – are normal… Less than three – change your glasses! 🙂


Did you think of a “red hammer”?

It is the answer given by 98% of people who did this exercise.

If you thought of something else, then you probably are one of the 2% of the people whose mind and thinking are quite different.

    Totally guessed that she wanted to see the man again.

    I prefer my answer to question 1: The “Young man” was at the mothers funeral because he was her lover and the father of her child. He and his daughter did what he does and what she was heritably inclined to do, and she became pregnant. When she discovered the truth she had a late term abortion, “killing” her “sister”

    well for the first question, i’ve already seen it so obviously i got the correct answer

    second i got 3 as expected

    third i said “yellow hammer” bc i originally thought of “silver hammer” and i was like, “they’re gonna expect me to say that so screw it!!! i’m going yellow!”

    Purple garden rake. and i figured the woman never met her real father and he showed up to the mothers funeral, she not knowing who he was falls in love with him and he’s sick and got her pregnant and a few days later she realized what happened so she aborted the thing. This was test was lame! who can’t see the ‘f’s??

    For the first one I figured the young man was her sister’s husband. She was estranged from her sister and so she had never met the man before the funeral. She killed her sister so she could be with the young man. Seemed like the only obvious answer to me.

    I’ve seen the second one before, so I got that right away.

    Yeah, I got a red hammer. Why is that? Can anyone explain it? I’d like to say that math makes me angry and want to hit something, but I know that’s not the case for everyone.

    1.) i assumed that she killed her sister so that her guy wouldn’t be tempted to want her – out of jealousy- or she found out they were dating so she killed her sister so she could be with him.
    2.) i found 5 F’s at first
    3.) Hammer, Blue
    i’m borderline genius lol

    For #1 I thought maybe the guy had fallen in love with the girl’s twin sister, so she killed her twin and was hoping to dupe the guy into having her instead?

    Well I’m a Psychopath for the first one

    Awsome! I am not a genius? Must be fake news. 🙂

    The first answer was clever and tragic. Left me wondering if he showed up. Couldn’t think of a motive except simple jealousy or something.
    2nd: counted six ‘F’s then realized there were technically no ‘f’s, they were all uppercase. I really thought that was going to be the answer.
    3rd: blue pliers.
