If monk 1 is infected, he knows this because he looked at all the other monks and no one had a green spot so he must have one.

If monk 1 and 2 are infected. Monk 1 sees the dot on monk 2 and assumes monk 2 is the infected one. Monk 2 sees the dot on monk 1 and assumes monk 1 is the infected one. The next day they see that the other remains and both realize that they must also be infected. This works for any number of infected monks.

The monks just dont feed the infected ones. They die and leave the monastery on the back of a cart.

Considering they're monks, they've been there awhile and know each other. If I were there and I saw that a a large majority of monks were looking at me daily, I'd know I'm infected.

The infected monks know they're infected because humans are naturally curious, all the monks want to know who the infected monks are. Obviously, if one monk gets more looks, he knows he's infected.

Leehovan, yep it's got something to do with enlightenment, but giving them books would be considered communication. Also, when they eat, each monk serves himself. The soup btw isn't clear enough to be used as a mirror.

Vix, you're on to something, but not quite... what if there's 12 infected monks and 19 healthy ones?
By looking at the other monks, each monk must determine whether he should leave or not.

A hint maybe, the fact that they are all dining together every day at the same time, makes the whole thing possible.

I will take a shot at this even though I am not sure how close to an answer I am. (First post as well!)

No body wants to eat with an infected bio hazard... not even a monk! (well at least thats my opinion)
If during lunch you are sitting across from a monk that does not have a green dot on his forehead and he gets up and moves to another seat, you can safely assume that you have a green dot on your head and you should pack your bags. (with no form of communication allowed, how could you dislike someone enough not to want to eat near them).

If a monk without a green dot sits in front of you and does not change seats you should also be pretty certain that you are not infected with green dot disease.

Through process of elimination (as meal times pass) eventually all green dot sufferers will know who they are and hit the road.

Well thats my idea, right or wrong I am enjoying your shard (been about 5 days now I think)
Keep up the great work,

If monk 1 is infected, he knows this because he looked at all the other monks and no one had a green spot so he must have one.

If monk 1 and 2 are infected. Monk 1 sees the dot on monk 2 and assumes monk 2 is the infected one. Monk 2 sees the dot on monk 1 and assumes monk 1 is the infected one. The second day they see that the other remains and both realize that they must also be infected and both leave.

If monks 1, 2 and 3 are infected, each will think that the other 2 are in the above situation. When they don't leave on day 2, he will realize he must also have a dot and all three will leave on day 3.

Following this theory, if 12 are infected, it will take 12 days for them to all to realize they have dots and all will leave on the 12th day.

Something still bothers me as not being right about this but I can't pinpoint it.

Now I have to go untwist my brain lol

Ah, yes, Vix you got it :)

Pip, yep that's the same puzzle. The answer would be 14. Ty for posting the link... my instructions I'm afraid weren't so clear.

To demonstrate with a simple example. Each monk thinks to him self, that he needs to count the number of other infected monks, then leave after that same number of days. Meaning that if he sees 4 infected monks, he will leave on the 4th day.
That way, the infected ones always see one dot less than the healthy ones. Since the dot that they can't see is on their forehead :)

So for example: There are a total 15 monks. 6 are infected, and 9 are healthy. The healthy ones see 6 dots, and would leave on the 6th day. But the infected ones see only 5 dots (the 6th dot being on their forehead), so they leave on the 5th day. And when the healthy ones already want to depart, they see that the infected ones already left, so they know they're healthy.

Now there's just the question on when they should leave... after dinner, during dinner, in the morning or in the evening :)

Congrats Vix, 30 ED coming your way.


Next puzzle:

How much dirt
Reward 10ED.

How much *cubic meters* of dirt is in a hole that is: 6.5ft by 3.8ft and 10 inches deep?

Trick question ;)

None. It's a hole so the dirt has been removed.
