Using brain teasers to build critical thinking skills
Here's a brain teaser: A rooster is on the roof of a barn facing east. The wind is blowing to the west at 10 miles per hour. The rooster lays an egg. Which direction does the egg roll?
The answer appears below the image.
Answer: There is no egg. The rooster didn't lay one because roosters are male. Did you get it right? Let's pick this apart and see why so many people have difficulty with this brain teaser, and so many others.
Watch the video below to learn more about how you can use brain teasers to improve your critical thinking.
The answer is in the details
It's easy to overlook details or accept them without questioning. In the brain teaser above, the answer could be found in the second word: r ooster .
In hindsight, we realize it's impossible for roosters to lay eggs. But it's easy to overlook this when it's casually mentioned in the brain teaser.
Misdirection
Another process at work in this brain teaser is misdirection . There were several details included that we may have paid too much attention to: The fact that the rooster was facing east, and that the wind was blowing west at 10 miles per hour.
In the end, these details had nothing to do with the actual answer. However, they seemed important in the context of the brain teaser! This directed us away from the relevant information.
Applying these ideas to the real world
The same techniques we use to solve brain teasers can also be applied to real-world situations . When you're trying to figure something out, it's important to analyze the information that's available to you and ask the following questions:
- Are there any key details I may be missing?
- Am I being misled by something?
- Could I be thinking about this in another way?
Brain teasers not only help to keep your mind sharp, but can help improve your critical thinking skills as well.
Let's finish things off with another brain teaser...
You are in a dark room with a single match. The only objects available to you are a candle, an oil lamp, and a gas stove. Which item do you light first?
Answer: The match!

Critical thinking puzzles for adults (with answers)
Critical thinking can help to better navigate the information-dense and complex world we live in. By thinking critically we can better identify priorities, take a sensible approach to problem-solving and reach conclusions logically in line with evidence. Puzzles are an excellent way both to learn and practice critical thinking skills.
If you’d like to learn more about critical thinking or simply practice your skills with some puzzles, then this is the article for you. Read a little bit more about critical thinking skills and how to apply them first, or just skip straight to the puzzles and see how you get on.
What is critical thinking?
Critical thinking is a broad approach to problem solving and analysis based on logic and evidence. It brings together a wide range of intellectual competences and the ability to combine and cross-reference them. Some of the most important elements of a critical thinking approach include:
Analytical skills:
- understanding of questions and concepts
- differentiation of relevant / irrelevant evidence and information
- identification of similarities, connections and differences
- use of metaphors or analogies to communicate ideas
Powers of inference:
- extraction of meaning from data using inductive or deductive reasoning
- extrapolation of data or abstraction into concepts and patterns
- correct identification and deployment of analogies and assumptions
- grasp of causal relationships, allowing development of conclusions and theories.
Data and theory evaluation:
- assessment of how strong, important or credible a theory might be
- taking on board new data and new arguments which alter understanding of ideas and theory
Rational decision-making:
– application of all the skills and competences above in order to come to a rational conclusion.
Problem-solving attitude: In addition to being able to think critically , you must also be personally inclined to think critically when facing a difficult or complex challenge. Developing qualities including curiosity and fairness, while distancing yourself from ideologies and group-think, should all help to create the kind of psychological landscape where critical thinking can flourish.
How can I learn critical thinking?
Critical thinking skills are hard to develop from only reading books or listening to lectures. The most effective way to sharpen and deepen critical thinking faculties is to practice critical thinking . Critical thinking puzzles offer a fun way to learn and the eight critical thinking puzzles we’ve chosen for this article should help you make a good start.

Eight critical thinking puzzles – with answers
Puzzle 1 – letter puzzles.
What common feature do the following words share?
Answer: All of these words begin with a vowel. This type of puzzle may send your mind off in the wrong direction, thinking about the objects or concepts described by the words, and the properties they might share. In fact, the solution lies in a far more simple consideration of the alphabet. Puzzle 1 is a simple example of a common type of letter or word puzzle.
Puzzle 2 – Commonalities and differences
What do the following items have in common and which is the odd one out?
Orange Juice
Answer: These items are all liquids and the odd one out is petrol, since all the others are drinkable liquids.
Puzzle 3 – Falling on his feet
A man who lives in a high-rise building decides to exit through the window one morning rather than using the door. Somehow he survives the fall without a scratch and walks away to work. How did this happen?
Answer: The man lived on the ground or first floor and merely stepped or jumped down to the pavement outside. By stating early on that the building in question was a high-rise building, it’s easy for someone reading quickly to assume that the man jumped from a window on a high store but this it s not necessarily the case.
Puzzle 4 – Walk this way
A group of five people enter a windowless meeting room together. An hour later when the meeting ends, four walk out of the door, leaving the room empty. What has happened to the fifth member of the group?
Answer: The fifth person was in a wheelchair and wheeled out of the room rather than walked. Solving this puzzle requires you to think laterally about the question and the possible solutions. The answer can be found by asking yourself whether the emphasis of the question is on the emptiness of the room or the means by which the other four people left.
Puzzle 5 – Shapes and symbols
When lying on my side, I am everything, but when cut in half, I am nothing. What am I?
Answer: The number 8. This puzzle requires that you think about a shape being repositioned or cut in a way that can change it to “everything” or “nothing”. Number 8 on its side is the mathematical symbol for infinity (i.e. everything) and also shaped like two small number 0s put together.
Puzzle 6 – Three hard options
The hero is escaping the lair of an evil super-villain and is faced with three possible exits:
- Door A leads into a pit of bubbling lava
- Door B leads to a room housing a deadly hitman
- Door C leads to the den full of lions that haven’t had a meal for a year.
Which door should the hero choose?
Answer: Door C. If the lion hasn’t eaten in a year, it will definitely be dead by now. This type of puzzle requires you to consider the full implications of the information given, rather than being drawn into a comparison of the relative dangers of lava, hitmen and lions…
Puzzle 7 – The bus driver’s eyes
You are a bus driver. Today the bus is empty at the start of your route but at the first stop, four people get onto the bus. Eight people get on at the second stop, while three alight. When the bus reaches the third stop, one more gets off, and three get on.
At the fourth stop, two people get off the bus and one gets on. The bus is traveling at an average speed of 30mph and its tires are new. What color are the bus driver’s eyes?
Answer: You are the bus driver so the color will be the color of your own eyes. This type of puzzle tries to confuse you and obscure the single piece of relevant information by presenting large quantities of irrelevant information.
Puzzle 8 – Losing weight
A man walks into a room, closes the doors behind him and presses a button. In a matter of seconds the man is 20lb lighter. Despite this, he leaves the room at the same weight he entered it.
Answer: The room in question is actually an elevator. When the man gets in and presses the button, the elevator moves downwards with an acceleration that reduces the effect of gravity and makes the man temporarily 20lb lighter. Once the lift stops moving, the man’s weight is subject to normal gravity, just the same as before. Solving this puzzle requires a small piece of general physics knowledge.
A final word…
We hope you’ve enjoyed our critical thinking puzzles for adults and that your critical thinking skills are feeling refreshed and sharpened after reading our article. Whether at school, in the workplace, or in general life, critical thinking can be a valuable tool for success and anyone can learn to use it.

7 Puzzles to Challenge Your Critical Thinking
Can you spot the connections and sort these items.
Posted March 5, 2015 | Reviewed by Ekua Hagan
The theme of this post is critical thinking—and the kinds of puzzles that can be constructed around it. This term is used frequently in psychology and education . There are various definitions, but the one that best suits our purpose and which is, in the end, perhaps the best, is the ability to comprehend the logical connections among ideas, words, phrases, and concepts . In the relevant scientific literature, of course, the term is used much more broadly as a framework for understanding human cognition . But in my opinion, the best way to understand things is to construct puzzles to illustrate their basic essence.
Critical thinking involves skill at recognizing a pattern in given information and especially recognizing how the information is connected to the real world. Here are a couple of very simple examples. First, consider the five words below:
- Cruise ship
- Walking on foot
- Automobile (not a race car)
Now, put them in order from the slowest to the fastest, when they are going at maximum speed. The solution, of course, is: 4-2-5-1-3.
As with all such puzzles, there might be slightly different solutions—one could claim that some automobiles go faster than cruise ships. This “indeterminacy” characterizes this kind of thinking. However, some puzzles are straightforward. For instance, what do the following five things have in common?
The answer? These are all words referring to shades of blue.
The seven puzzles below are to the ones above, though hopefully more challenging. Some involve knowledge of facts, but critical thinking is still involved in such cases because the organization of the facts according to some principle is always involved—for example, a puzzle may ask you to put five items in order of their dates of invention.
The following tongue-in-cheek definition of critical thinking by Richard W. Paul, a leading expert on critical thinking theory, says it all: “Critical thinking is thinking about your thinking while you’re thinking in order to make your thinking better.”
I. What do the following 5 things have in common?
- Orange juice
II. Put the following buildings or structures in order of height, from the shortest to the tallest.
- Typical camping tent
III. What do the following animals have in common?
IV. Put the following inventions in order from earliest to most recent.
V. What feature do the following words have in common?
- Imagination
VI. Put these bodies of water in order in terms of volume, from smallest to largest .
VII. What do the following landmasses have in common?
I. They are all drinkable liquids. II. 5-1-4-3-2 III. They all have a tail. They are also all quadrupeds. IV. To the best of my knowledge: 5-4-3-1-2 V. They start with a vowel: a, e, i, o, u VI. 4-2-1-5-3 VII. They are all peninsulas.

Logic and Lateral Thinking Brain Teasers
Logic and lateral thinking brain games provide a complete mental exercise by working on both logic and creative thinking. Some of these brain teasers require you to find the logic behind the puzzle to get the solution while some require out-of-the-box thinking that breaks from the traditional notions. Try these ones to get started.
1. Which Way Is the Bus Going? (This Is a Bus in the US.)
Answer: The bus is traveling left.
Look at the bus — the doors are not visible. This means the passengers would get on the bus from the opposite side. And since the bus is in the US — where they drive on the right side — the bus is traveling left.
Did you know kids are slightly quicker in answering such visual brain teasers (although they can be inaccurate sometimes)? And research by the University of London found out this is because children under 12 perceive visual information differently from adults.
2. This Brain Teaser Requires High Observation Skills: Guess Who’s Married?
This brain teaser is all about observation and some logic-lateral thinking. Look at pictures carefully, do you see any signs or indications to identify a married woman? Yes, the second woman has a ring on her ring finger.
3. Find Which Glass Will Fill up First? (Tip: Look at the Pipes Carefully.)
If you thought it is 6, it’s wrong. Look at the pipes connected to beakers. The lower pipe connected with the first beaker is closed — the water won’t go through it.
So now eliminating options with closed pipes, it’s the beaker number 5 that’ll fill up first.
4. This Logic Brain Teaser Will Test Your Visual Judgment.
Just look at the opposite sides of the triangle. You’ll get the answer.
5. Guess the Car’s Parking Spot Number.
To solve this you’ll need to look at the puzzle from a different angle. What you see are inverted numbers, the actual sequence is 86, 87, 88, 89, 90, 91.

6. guess the correct top view of the tower..
First, look at the reference tower carefully. It has orange on the top, yellow beneath it — but of equal size so won’t be visible from the top, a larger yellow with a slightly larger orange at the bottom.
So the aerial view of the tower should consist of a pattern from a smaller orange pattern followed by a larger yellow base and again comparatively larger orange. That’s the first pattern — A.
7. Can You Guess the Total Number of Blocks?
Did you count the blocks that are hidden behind? The bottom layer has 5 blocks, the second layer has 3 and the top layer has 1 block.
Visual Puzzles and Brain Teasers
Visual puzzles test your ability to visualize things. If you have a knack for visual-spatial judgment, you might have visual-spatial intelligence — one of the intelligences as per Gardner’s theory of multiple intelligences — that enables you to think in three-dimension and picture concepts in mind.
8. Can You Spot the Panda?
9. Can You Spot the Pig?
10. Can You Find Which Butterfly Will Reach the Flower First?
So how long did you take to find out?
Mazes are great brain teasers because it really makes you think. To navigate through a complex labyrinth and find out a way, you indeed have to use enough cognitive resources. Mazes are also great brain games for kids as they help build their problem-solving and visual-motor skills.
11. Guess the Correct Shadow.
12. quick — can you find the mistake.
Answer: “Mitsake” is the mistake.
It’s funny how our mind fails to recognize the simple mistake. This phenomenon is called intentional blindness in which we fail to notice other things while focusing on one particular object. Here, you were focusing on numbers and missed the word.
13. Stroop Test
Stroop effect is the phenomenon when you recognize the semantic meaning of the word instead of the color. If you’re doing it for the first time, it can be difficult to recognize the color as the meaning of the words conflicts with your brain. Try it yourself.
Speak the color of the words — not the semantic meaning — from the following graphic.
14. Advanced Stroop Test
Along with the colors, shapes are added in this Stroop test to challenge your brain. Try it.
Speak out the color and shapes — not the semantic meaning of the word — in the following graphic.
Riddle Brain Teasers
Riddles are the old but goodie brain teasers that have stood the test of time. They are fun, engaging, enable you to think creatively, and of course, utterly satisfying. Here, let’s start with some easy ones.
15. What’s the Thing That Shoots but Never Kills?
Answer: Camera
Okay, that was an easy one. Let’s see if you can solve the next riddle.
16. Who’s the Doctor?
Answer: The doctor is the boy’s mother.
The picture of fishing with the son conjures a “son-dad time” picture. Our mind perceives it must be the son’s dad or a male figure who went fishing. Well, that’s how these riddles play with our minds.
17. A Woman Born in 1975 and Died in 1975. She Was 22 Years Old at the Time of Death. How?
Answer: One of the numbers (1975) could be the hospital room or even a postal code.
Science-Based Brain Teasers
At some point, we all have studied the basic principles of physics, chemistry, and other science. But what’s funny is these basic principles and laws have washed away from our memory, sometimes making us wonder about the basic science behind the things.
These science-based will take you back to the science class and test your knowledge with some brain-teasing science problems.
18. Look at the Picture: Will the Scale Remain Balanced or Will Tilt To One of the Sides?
Answer: It will tilt.
It’s because of the principle of Buoyancy. Although the two objects are of the same weight, when they are immersed in water they go through weight loss. And the weight loss is equal to the water displaced. So the larger object — the stone — will displace more water than the iron weight. So the scale will tilt.
19. Brain Trivia: Name One Animal That Has Blue Blood
Answer: Octopus, Squid, Horseshoe Crabs
The reason why these animals have blue blood is because of hemocyanin, a copper-rich protein present in their blood. While animals with red blood including humans have Hemoglobin, an iron-containing protein responsible for the red color.
Math and Number Brain Teasers
Math brain teasers are a treat for every math lover. Some require pure logic and a knack for calculations while others are just lateral thinking problems masquerading in numbers. We’ve put together some of these brain teasers to get you started.
20. What’s the Missing Number?
This brain teaser requires you to observe the number and find-out the logic. Look carefully the number in the center circle of each line is half the sum of numbers towards its left and right. So, for the last line, the answer’ll be: 9 + 3 = 12 (÷ 2) = 6.
21. Find the Total Number of Students in the Class.
Since Alex ranked 9th from the top there are 8 students ahead of him. And he ranked 38th from the bottom that means 37 students are behind him.
So the total number of students will be 8 + Alex + 37= 46.
22. Number Brain Teaser – Guess the Missing Number.
Here’s the trick. The wheel is a piechart. Each number and the section represents the percentage. So 100 – 66 (total of the numbers) = 34. Were you baffled?
23. Can You Guess the Number?
The trick is to count the total number of intersections. In the first the lines intersect 9 times, in the second it’s just 1 and in the third one it’s 4 times.
24. What Should Be the Time in the Last Watch?
Answer: 7:05
Observe the time difference in each watch, there’s a pattern.
(1st watch) 9:05 – 12 mins = 8:53 (2nd watch)
8:53 – 24 mins = 8:29 (3rd watch )
8:29 – 36 mins = 7:53 (4th watch)
7:53 – 48 mins = 7:05 (5th watch)
