PT 33 Sec 4, Game 3 Forum

[niederbomb]

I solved this one in 11 minutes 5/6 (dumb error) but ran out of time for the last (easy lights) game on the section.

What's the best strategy to solve this type of game? I could not figure out an effective way to diagram it, so I just applied the rules to the answer choices and eliminated as many as possible, which was very slow. I wasn't even sure I got the right answers, so I was surprised I only got one wrong.

Is there a way to template this game?

How about Game 2 in this section? It was also a pain in the a**.

The conflict between having both W and Z tells us that we can only have either 2 or 3 topazes, which greatly restricts the number of variables that can be selected from each group.

If we have only 2 topazes, then we will have either 1 ruby and 3 sapphires, or 3 rubies and one sapphire.

If we have 3 topazes, we will have either 3 rubies and 0 sapphires, 0 rubies and 3 sapphires, 1 ruby and 2 sapphires, or 2 rubies and 1 sapphire.

More succinctly, for rubies, sapphires, and topazes, respectively:

R-S-T
1-3-2
3-1-2
3-0-3
0-3-3
1-2-3
2-1-3

This is the key inference for the game and should make the questions much easier.

The existence of categories (types of stones) for the variables (the stones themselves) is a hint that determining the numbers of stones chosen from each category in various scenarios may be the way to break the game open.

***

For PT33, Game 2, connect the rules that mention the same variables to create long conditional chains, linking as you go.

If H in requires G out, and either J or M alone is sufficient to require H, we can then say that:

J or M -> H -> NOT G

Contrapositively, G in requires H out, which requires J and M out.

G -> NOT H -> NOT J and NOT M

etc.

I just took this test. 173. -4 RC, -4 LR, -2 LG.

Game 2 I missed Q9. Game 3 I missed Q14.

Q9 was an extremely stupid mistake... don't know what I was thinking. For Q14, I made a hypo that had 2 of each type of stone that I thought was right. Really dumb. Gah!

I scored 171 doing 30-minute sections. -0 RC. -6 LR (time). -6 LG (time). I missed Q #17 because I didn't correctly apply the deduction that either Z or W must be out, forcing either X or Y in, always. I ran short on time and guessed E.

Thanks. This numerical distribution mostly helped with Q's #14, #16, and #18. However, I still had to apply the rules to each answer choice for the other questions, the ones that used names instead of numbers. I still think this game would take me 10 minutes if I had never seen it before.

On the bird game, I guess I already did what you suggested: I just moved like molasses to actually make it work, taking almost 10 minutes.

Where can I find a list of in-out games? I know about dinos, but what others?
