How many bricks are needed to finish constructing a brick building?
Show Answer
Answer: one brick–the last one
The trick in this question is in the wording. It asks how many bricks are needed to complete the building, not how many bricks were used in total. No matter how many bricks were used to build it, the answer is just one—the final brick that finishes the construction!
Turn me on my side, and I become everything.
Slice me in half, and I become nothing.
What am I?
Show Answer:
Answer: 8
The answer lies in how we look at the number 8:
- Turn it on its side (∞), and it becomes the infinity symbol, which represents everything—endless, limitless, forever.
- Cut it in half (8 → 0), and you’re left with zero, which means nothing at all.
It’s all about perspective!

Answer: No Burials Needed

It’s a trick question designed to make you focus on the border instead of the real catch—the word “survivors.”
In a room with five sisters, each one is occupied with something. Emma is reading a book, Sophia is cooking, Lily is playing chess, and Olivia is doing the laundry. What is the fifth sister doing?
Answer:
Answer: Playing chess with Lily
Since there are five sisters in the room, and four of them are busy with different activities—Emma is reading, Sophia is cooking, Lily is playing chess, and Olivia is doing the laundry—we need to figure out what the fifth sister is doing. The key detail here is that Lily is playing chess, and chess requires two players. Since no one else in the room is available to play, the only possibility is that the fifth sister is playing chess with her!
