Diagram

[ohthatpatrick]

Here's a .pdf showing how we diagrammed this one and worked through the questions.

Did you have a different way of doing it? We love to hear it / see it.

And if you're having trouble following our inferences or symbolization, feel free to ask us follow-up questions.

how do we get the idea that Y is at 4-7?

[ripan.hans]

Y can't be 1st because of our S>Y rule. Y can't be second because this would mean S1 and Q3, but spaces 4-7 would not leave sufficient space to separate J, G and H in accordance with rule 1. Y cannot be in 3 because this would place S ahead of it, but because of rule 2, Q would have to come before S (S cannot be before Q because Y, in this case, is already in 3), this would force Q-S to be consecutive, which is a violation of the first rule.

I think the diagram for Q23 should be C) j Q g R h S Y

Hey all! Here's my diagram for Game 4. I'll be posting solutions to the individual questions within the game thread based on this diagram. Let me know if you have any questions!

ohthatpatrick's diagram indicates Q22 (E) h Q j R g S Y
It violates the rule of j _ __ + _ g _ R, I think it could be
j Q g R h S Y

Hi I am a bit confused with one of these games rules.

S can be earlier than Q only if Q is third.

S_Q --> Q3

Q3 --> Q___+ _ S_Y

I am confused by this rule. I think the Can throws me off for some reason. I feel that when the can is there, I should also immediately write Q-S--> Q3 besides it because this could also happen.

What am I missing and any advice on "Can"

This game is the hardest game I've encountered.

As a matter of fact, I would choose the Mauve dinosaur game over this...

But, allow me to explain what the second rule actually says.

"only if" introduces the necessary condition so if you diagram it:

S - Q -> Q3

It's pretty easy. So whenever S is put before Q, then Q has to be in third place. So When this happens, S is going to be either 1 or 2.
Extra info: due to the first rule, since Q ans S cannot be together, when this rule kicks in, S HAS TO BE in the FIRST place

Are we done? Are we ready to take the contrapositive? NOPE!
Does that mean when Q is in the third place, S has be in the first place? NOPE! Q is a necessary condition. This means when Q is in the third place, this does not implicate that S has to be before Q (if you don't know this... you would have to review the suff/nec concept).

So what does that mean? When Q is in third, S COULD be placed later than Q. So... by this rule, S could either before or after Q3.

NOW! let's talk about contrapositive.

When Q is not in third, what happens? S has to be AFTER Q. Before's logical opposition is "After." So... when we diagram this:

~Q3 -> Q -S

Extra information: combining with the 3rd rule, when ~Q3 -> Q - S - Y

Another extra information about third rule: combining with the 3rd rule, you can also diagram it as S -Q and S - Y -> Q3

Also, I want to share my secret with you guys.

I actually split up the board based on the second rule. When you do it, you get 3 possibilities or frames.

Even though it's not much, I found it very helpful.

No 1 Frame

Basically, what you do is you assume that the second is kicked in. So what you get is _ _ Q _ _ _ _ and S being somewhere either in the first or second. However, since Q ans S cannot be together, S has to be in the first place. Now, for the remaining, the J or H has to be in the second. Why? Because otherwise, you have J , H , and G among the four spots; how are you going to split it? So you get S J/H Q _ _ _ _

You could actually split this No 1 into another one. remember how I said that just because Q3 does not mean S -Q? So you could set up the game so that Q is in the third and S is after Q. But this wouldn't work out. Try it

No 2 Frame

In this one, you assume that Q is NOT in third. What does that mean? Q - S - Y and J - G - R relationship kick in. Too many possibilities though. Where Q is gonna go? what about J? I know... but if you actually think about it, Q can't be in 7th nor 6th or 5th due to first and second rule. So Additionally, Q can't be in third; so Q only could go 1st, 2nd or 4th. If you try 4th, it doesn't work out. So what do you have left? 1st or 2nd.
So you make a frame assuming that Q is in the first place.
With J - G -R rule, you realize that second place has to be either J/H. This isn't much but this is something.

No 3 Frame
Now, you assume that Q is in the second one. Actually there are no other implications out of this one... it's really really said. But there are a lot of restrictions though. For example, the first one cannot be R or S; The 3rd one cannot be Q or R or S; and you realize that J can't be in 7th, 6th, 5th, or 4th. So J has to be in either 1st or 3rd. With this restriction, you could see a lot of things.

I hope this really helps... I feel naked now...

Would it be possible for someone to post some similar games to this one? Particularly, games of similar difficulty as well as type. Thank you!
