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?

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.

The key is the special person. There's one special person, called the counter. He's the one who will eventually say that all prisoners have been in the room.

MattEmAngel, it's not that. It's this idea of the one counter.

Ok, well I think I have it then.

Leo is an awesome guy, so he gets chosen to be the leader because he was the first person to go inside. He tells everyone else that when they go in they must turn the light off if it was on when they entered. Once you turn the light off if you are chosen to go again you must not touch anything. If you come into the room and find the light off you do not touch anything. Every time this awesome guy that happen to be called Leo walks in he turns the switch on. He keeps count of every time he does this and when he gets to 99 he wins.

I still stick with suing the government for trauma and distress.

Just realised you can switch on and off in my answer and then that awesome guy wouldn't have to go first.

If the light is on, no one touches it except Leo. When Leo touched it he counts one.

When the light is off if anyone goes in there they must turn it on. However if they get chosen again and the light is off they do nothing.

(This is if everything is switched from my answer)

Leo is correct, however everything is reversed. The special guy always turns the light off.

So.

Basically if the light is on, no one can touch it. If a prisoner comes in, and it's his first time, he turns the light on. (It starts in the off position.) After this prisoner turns it on, no one touches it until the leader comes. The leader always turns it off. Then, when someone else who has never gone goes, he turns the light back on until the leader comes again and turns it off. This goes on until the leader counts 99 times. Then he knows that everyone else has gone.

So leo was right but he had his offs and ons mixed up.

Okay. So they choose "23" to be the counter. 23 alone recognizes when everyone else has gone. That means that a consistent process must exist that means nothing to the others but everything to 23.

Person 1 walks in. The lightbulb is off. He leaves it off.
Person 2 through 99 leaves the lightbulb off.
23 sees the lightbulb off. He turns it on. That means that the counter has been there and has left a mark.

Now the counter has to know when 99 other people have been chosen.

Person 24 (or whatever number) walks in and sees the lightbulb on. He can't turn it off because it will reset....no it won't.

Everyone leaves the bulb off except 23. When he arrives, he turns it on. The next person, 47, remembers that the bulb was on when he arrived. He turns it off. It continues until 23 is chosen again. He turns the bulb on. The next person, 83, turns it off. 47 sees the bulb off and leaves it off, remembering that he has gone. If 47 is chosen after 23 again, he leaves the bulb on for the next person.

This continues until 23 walks in and sees the bulb on. Everyone ahead of him has left it on for the next person. He will be the last person and will announce that all 100 have been to the lightbulb. And he will be correct.
