So, there was a thread on here a while back dedicated to riddles. Thaboss hasn't seen any new thread recently, so he's decided to start his own. Feel free to post and respond to any riddles.

Here's a classic one.

Bob hates his job. One day, while Bob is working on the 34th floor of an office building, he decides he's fed up with it. He rips open a window, and jumps through it. Although Bob is on the 34th floor, and there was nothing to stop, slow down, or cushion his fall, when he landed, he was perfectly fine. How?

I almost have it already. Check my logic.

The prisoners cannot communicate verbally, nor can they leave written messages. The messages must therefore be visible. The only way they can leave a visible message is with the lightbulb.

They can't choose to do nothing, because they would never know who had gone and when. They can't leave the lightbulb on permanently because the same would apply. If they alternate (one turns it on, one turns it off), they will lose the pattern the instant someone is used twice.

They must find a way to each leave an individual mark/clue, so that twenty marks will show that they have gone twenty times. If a prisoner is selected twice, he would do nothing because he has seen his mark.

He feels the light bulb. If it is warm then he'll know another person has turned on the light.


The prisoner needs to know that all the other prisoners have been in the room. And he could come in to the room and see the light bulb on. Perhaps thaboss explained it wrong. When a prisoner goes into the room he can turn the light bulb on, or leave it off. If the light bulb is already on (if another prisoner has been in the room and decided to turn it on), then he can turn it off, or do nothing. And the light bulb starts in the beginning as off.

That would only work the first time. After that, the lightbulb would always be warm and they could never know when all twenty had gone.

MattEmAngel's logic is near perfect.

Something HAS to change every time. There would be no way to establish a pattern when you could only leave three clues: on, off, of warm. A person would have no way to know they had gone more than once, and the next person would have no way to know how many had gone before him unless there was a way to leave twenty different marks. No pattern could compensate with so many random variables.

Something does not have to change every time. And warmth of the light bulb is not a variable. The prisoners aren't allowed to feel the bulb, just the switch. Thaboss misunderstood the last part of your first post. Each person does not have to leave a mark every time.

Ah, my mistake. I didn't read into it enough.

They can't choose to do nothing, because they would never know who had gone and when. They can't leave the lightbulb on permanently because the same would apply. If they alternate (one turns it on, one turns it off), they will lose the pattern the instant someone is used twice.

They must find a way to each leave an individual mark/clue, so that twenty marks will show that they have gone twenty times. If a prisoner is selected twice, he would do nothing because he has seen his mark.


OH! After reading this I nearly have it.

If one person is chooses to always turn the light on when he goes in, everytime he sees the light off he can add one to the number.

But how to tell other people to turn on the light, I don't know. And that would mean he had to get picked 99 times.

Better off just waiting 3 years and reporting the jail to the government for disrupting mental health.

Leo is correct with his idea of choosing one special person. But he's off with the method.

And there is no time limit. Another hint. This takes a LOOONG time.

Sorry, *chosen

It was killing me.

Also, is there an interaction with other prisoners?

How could you possibly know that 19 people had gone ahead of you when the only clue you have is "on" and "off?" You get chosen, you get chosen again, someone else gets chosen, you get chosen again. You see "on" or "off." What possible pattern could exist?

You would...have to leave a clue...for yourself. Something specific would have to be different.

But it would only work if you got chosen again! The 19th person doesn't know that they are #19. If everyone went once, in a straight line, there is no possible way that #19 could show #20 that he was the last to go.

They are allowed to discuss their plan beforehand but that is all.No interaction after that.
