10 Brain Teasers And Riddles Only Smart People Can Solve

Roses are red, and violets are blue. Solving these ten riddles comes easy to clever people. Do you think that’s you?

1. Riddle One

The first one is, “If you have me, you want to share me; if you share me, you don’t have me.” 

1. Riddle One

top secret

This riddle can be tricky because many things can be shared once you have them. But as you go deeper, you realize the answer is a secret.

2. Riddle Two

The second riddle reads, “You are escaping a labyrinth, and three doors are in front of you. The door on the right leads to a raging inferno, the door on the left leads to a lion who hasn’t eaten in three months, and the one in the middle leads to a deadly assassin. Which one do you choose?”

2. Riddle Two

I am sure you are wondering how you got to any of these doors in the first place. But thank goodness it’s hypothetical. However, if you thought the door on the left was the safest door to choose, you would be right.

3. Riddle Three

Riddle Three can be a one-liner, but it is also as difficult. “If I’m holding a bee, what do I have in my eye?” 

3. Riddle Three

The answer is beauty. The riddle is a play on the proverb, “Beauty is the eye of the beholder.” Or the bee-holder, buzz buzz. 

4. Riddle Four

Riddle Four is another challenging brain teaser. “An old man dies, leaving behind two sons. He orders his sons in his will to race with their horses — the one with the slower horse will receive his inheritance. Both sons race, but since they’re both holding their horses back, they go to a wise man and ask him what they should do. After that, the brothers race again — this time at full speed. What did the wise man tell them?” 

4. Riddle Four


The answer to this is the wise man tells them to switch horses. After switching horses, whoever wins the race will get the inheritance because they still own the slower horse. Easy right? 

5. Riddle Five

If you thought Riddle Four was hard, you are in for a treat from Riddle Five. This riddle tests both your intelligence and your knowledge of numbers. “Turn me on my side, and I’m everything; cut me into half, and I’m nothing. What number am I?”

5. Riddle Five

The number is 8. On its side, you can see that it looks like an infinity symbol — which technically means everything. If you cut it into half, number 8 becomes two zeros — which means nothing. IQ> 200, assemble!

6. Riddle Six

Riddle six is ” If you have a 7-minute hourglass and an 11-minute hourglass, how can you boil an egg in exactly 15 minutes?” 

6. Riddle Six

To answer this question, you must bring your knowledge of math into the question. As you start boiling the egg, start both hourglasses. After the 7-minute hourglass runs out, start it again.

When the eleven-minute hourglass runs out, turn the 7-minute hourglass again. You can wait for the 7-minute hourglass to run out, giving you exactly 15 minutes of boiling time.

7. Riddle Seven

How good were you with arithmetic progression? Well, riddle seven has something for you. “What’s the next in the sequence of numbers: 1, 11, 21, 1211, 111221, 312211, 13112221?”

7. Riddle Seven

Answer: 1113213211

Each sequence of numbers is a verbal of the sequence before it. The first one is “1,” followed by “11” or “one one.” That sequence is followed by “21” or “two one,” and so on.

8. Riddle Eight

Riddle eight goes, “Four people arrive at a river with a narrow bridge that can only hold two people at a time. It’s nighttime, and they have one torch that has to be used when crossing the bridge. Person A can cross the bridge in one minute, B in two minutes, C in five minutes, and D in eight minutes.”

“When two people cross the bridge together, they must move at the slower person’s pace. Can they all get across the bridge in 15 minutes or less?”

8. Riddle Eight

Person A, B, C, and D can all get across the bridge in 25 minutes or less. First, Person A and B can cross the bridge, and A brings the torchlight back. This takes three minutes. Person C and D can cross, and B brings the light back. This takes another three minutes. Finally, A and B cross with the light for another three minutes.

9. Riddle Nine

Like Riddle Eight, Riddle Nine is another brain teaser that boggles even the smartest, especially those who have no idea how to take care of animals.

“A farmer needs to take a fox, a chicken, and a grain sack across a river. The only way across the river is by a small boat, which can only hold the farmer and one of the three items. Left unsupervised, the chicken will eat the grain, and the fox will eat the chicken. However, the fox won’t try to eat the grain, and neither the fox nor the chicken will wander off. How does the farmer get everything across the river?”

9. Riddle Nine

child with chicken

Well, he must take these steps to get everything across the river. First, he must take the chicken across the river and return with an empty boat.

Then, he takes the grain across the river, drops it, and brings back the chicken. He also takes the fox across the river and comes back with an empty boat to take the chicken across the river.

10. Riddle Ten

Our final riddle will have you thinking for hours. “There are five bags of gold that all look identical, and each has 10 gold pieces in it. One of the five bags has fake gold in it. The real gold, fake gold, and all five bags are identical in every way, except the pieces of fake gold each weigh 1.1 grams, and the real gold pieces each weigh 1 gram.

“You have a perfectly accurate digital gram scale and can use it only once. How do you determine which bag has the fake gold?”

10. Riddle Ten 

heavy bag

The process is to find out which is real gold, you need to take one piece from the first bag, two from the second bag, three from the third bag, and so on. If the weight on the scale ends in .1, you know it is the first, .2 it is the second, .3 it is the third, .4 it is the fourth, and .5 it is the fifth.
