What's your favorite Enigma / Riddle / Sentence Puzzle?
Tomorrow is a big event at my university. I'd like to make a fun thing where the people of the Board Game society I am in can try to find me for a riddle, kind of a Where is Waldo in a place where there is a crap tone of people to find the NPC that'll give them a Riddle (Maybe something to win? No idea how I could do that detail)
We have similar one in Czechia.
John Doe bought twenty mice.
The next day, he bought twenty-one mice. How many mice does he have?
The solution is zero, because in czech, you can say twenty-one mice the same way as poison for twenty mice (jednadvacet myší - jed na dvacet myší).
Just thought it's interesting that this works in other languages too.
In French we have "Vingt cent mille ânes dans un pré et cent vingt dans l'autre. Combien de pattes au total ?" = "Twenty hundred thousand donkeys in a meadow and a hundred twenty in the other. How many legs total ?" Answer is six, because it can also be read as "Vincent mit l'âne dans un pré et s'en vint dans l'autre" = "Vincent put the donkey in the meadow and went to the other." So two legs for Vincent and four for the donkey.
We also have "The wheat, or the sheep ?" Answer is "at the mill", because "or the sheep" is pronounced the same as "where does one mill it" (ou le mouton - où le moud-on).
North pole is in the middle of the room.
That also indicates the color of the the bear, because polar bears actually live only on north pole if I'm not mistaken.
An explorer leaves his camp and walks 1km south until his path is blocked by a huge bear. He makes a 90° turn to his left and sprints 1km east. After checking the bear is nowhere in sight, he turns another 90° to his left and walks 1km north, arriving back at his camp. What colour was the bear?
For me, unless I'm missing something, that's an easy "Yes".
If someone randomly asks me for a single dollar they probably need it more urgently than I do. And if it's some kind of weird scam? I'm still only out $1.
(No, I will not be sending $1 to people that reply to this, but I pre-acknowlege that you're very clever for thinking of that)
You are in a room with two doors. Each door has one guard. One door leads to heaven and the other leads to hell. You have to choose one door and once you choose it, you have to go there. Before you choose, you can ask one of the guards one question. One of them always lie and the other always tell the truth. You don't know which guard is the liar/truth teller and you don't know which door leads to hell/heaven.
What's the question you ask the guard?
If I'm not wrong the answer is something a bit twisted lie "If I where to ask you if you are guarding the right door, would you say you are?" Which because it's a double lie, there is a way where they cross each other
You answer is right.
I heard the solution as follows:
Would the other guard say that you are guarding the right door?
And then you revert it.
Yours solution is better.
The XKCD and the video made me laugh, thanks.
The guard replies either four or something else.
You now know which of the guards is the liar and who is the truth teller.
You used your one question and still have no clue which door leads to hell and which leads to heaven.
You have to guess 😕.
My favorite longer puzzle is “there’s a naked man lying dead in a field with a stick in his hand. Asking me only yes/no questions, tell me why he is in the field and how did he die?”
I love them as well! I only know a couple, but I first heard them at a summer camp and they’re a great way to pass time with new friends while traveling.
It's a prank riddle. Basically you make two statements about building bridges. They can be from anywhere and to anywhere else. My nose to your forehead, Baltimore to Seattle, it makes no difference. In one sentence, you use the word "okay" and in the other you don't. The sentence with "okay" in it produces a good bridge. The sentence that doesn't, doesn't.
When you ask a person to build their own bridge, if they say "okay" in the sentence, it's a good bridge. If they don't, it's a bad bridge and it falls down. This setup is built to make people frustrated because "okay" is one of those filler words that people don't really pay attention to in sentences.
I've also heard of a similar setup where a person hands an object to another person (again, the object doesn't matter) and says "This is a bean, okay?" And if the recipient says "okay" then they have done the task correctly and can pass it along to another person, declaring the object is something else. If the receiver doesn't say "okay," then something went wrong and one of the people who is in on the joke interrupts and starts the process again. with a new object.
I know a similar one where you say some kind of finger counting verse, in the end you put your arms akimbo and request the other person(s) repeat it. It doesn't matter if they get the finger counting right, because it only counts if they also get the akimbo correct.
It's fun to do in a group of slightly drunk people, until all got it but one. Then it feels like bullying... :/
This one is kinda hard to describe, so I'm including an image.
Four people are standing in a row and all are looking to the right (EDIT: On the image, the fourthperson is looking left. That doesn't matter, because nobody can see through the wall). First and third person have blue hat, second and fourth have red hat. There's a wall between third and fourth person.
Nobody knows what color is their hat. Everybody can only see hats of people on their right side (left/right sides are from the perspective of us, seeing them from the side). Nobody can see through the wall. For example first person can see the second and the third person. The second can only see the third person. They know that two of them have red hat and two of them have blue hat. They are told that if anybody says aloud the color of their hat, they are free to go. (They are captives or something). If anybody says the wrong color, they are all gonna be killed. They can't obviously turn around, talk to each other or something like that. They can't guess.
Are any of them going to tell his hat's color?
Let's number the dudes in your image form left to right: 1, 2, 3 and 4.
Dudes 3 and 4 have no useful information. They stay silent.
Dude 1 can see one of each hat colour on the dudes in front, but cannot determine their own colour without knowing the hat colour of dude 4. They stay silent.
Dude 2 can see the hat colour of dude 3. They can determine that either they themself or the dude behind must have a different hat colour. The dude behind - dude 1 - can see both of the hat colours in front, but stays silent. This lets dude 2 know that they and dude 3 must be different colours (otherwise dude 1 would have known their own hat colour).
Therefore, dude 2 knows their own hat colour must be different to the dude in front and announces the colour of their own hat.
