Brain teasers require you to approach problems from different angles, thereby improving your analytical and logical reasoning abilities. This skill is invaluable in both academic and real-world situations.
3. Provides a Fun and Engaging Activity
Unlike standard exercises, brain teasers are often entertaining and can be a fun way to pass the time. They can also serve as great icebreakers in social settings.

Examples of Intermediate Brain Teasers
Below are several intermediate brain teasers that will challenge your mind and encourage creative thinking:
1. The River Crossing Puzzle
You have a wolf, a goat, and a cabbage. You need to cross a river with them, but your boat can only carry you and one of the three at a time. If you leave the wolf alone with the goat, the wolf will eat the goat. If you leave the goat alone with the cabbage, the goat will eat the cabbage. How do you get all three across the river safely?
2. The Missing Dollar Riddle
Three friends check into a hotel room that costs $30. They each contribute $10, giving the hotel clerk $30. Later, the clerk realizes the room should only cost $25, so he gives the bellboy $5 to return to the friends. The bellboy, however, keeps $2 for himself and gives $1 back to each friend. Now, each friend has paid $9 (totaling $27), and the bellboy has $2. What happened to the missing dollar?
3. The Siblings Riddle
A man is looking at a picture of someone. His friend asks him, "Who are you looking at?" The man replies, "Brothers and sisters, I have none. But that man's father is my father's son." Who is the man in the picture?
4. The Hourglass Problem
You have two hourglasses: one that measures 7 minutes and another that measures 4 minutes. How can you measure exactly 9 minutes using only these hourglasses?
5. The Light Switch Riddle
You are in a room with three light switches that control three light bulbs in another room. You can’t see the bulbs from the switch room. You can flip the switches as many times as you want, but you can only go into the bulb room once. How do you determine which switch controls which bulb?
Answers to the Intermediate Brain Teasers
Below are the solutions to the brain teasers mentioned above:
1. The River Crossing Puzzle
- Take the goat across the river first.
- Go back alone and take the wolf across.
- Leave the wolf on the other side, but take the goat back with you.
- Leave the goat on the original side and take the cabbage across.
- Leave the cabbage with the wolf and return alone to get the goat.
- Finally, take the goat across again.
2. The Missing Dollar Riddle
The confusion comes from adding the $2 the bellboy kept to the $27 paid by the friends. Instead, you should subtract the bellboy's $2 from the $25 room cost, which accounts for the total correctly. So, there is no missing dollar.
3. The Siblings Riddle
The man in the picture is his son. "My father's son" refers to himself, and therefore, the man in the picture is his son.
4. The Hourglass Problem
- Start both hourglasses at the same time.
- When the 4-minute hourglass runs out, turn it over (4 minutes have passed).
- When the 7-minute hourglass runs out, you have 7 minutes. At this point, the 4-minute hourglass has been running for 3 minutes (since you flipped it after 4 minutes).
- When the 4-minute hourglass runs out again (4 minutes from the start + 3 minutes = 7 minutes), turn it over again.
- When it runs out this time (which will take 4 more minutes), you will have measured a total of 9 minutes.
5. The Light Switch Riddle
- Turn on the first switch and leave it on for about 10 minutes.
- After 10 minutes, turn off the first switch and turn on the second switch.
- Go into the other room. The bulb that is on is controlled by the second switch. The bulb that is off but warm is controlled by the first switch. The bulb that is off and cool is controlled by the third switch.
