Hi guys,

I'm going through a book on logic games (I plan on going through the logic games bible later on). In the book, the author is breaking down the solution to a past question (September 2007 LSAT. Game 1; Q1-7).

In the picture above, he said 'the latest H could be open is 6th'. Since O and L is opened after H. I don't agree with this completely, because we also have 'I' above in the diagram. It is very likely that 'I' happens before 'O'. As a result, we should have 3 items after 'H' and not 2.

Does anyone have access to the question or will it be bette I post it all?

Thanks in advance.

Hi Tester, let me see if I can help! First, we have an active thread on that game, but we haven't done a detailed breakdown of the setup yet. That thread is here if you want to check it for help on specific questions, and we will at some point do a more complete setup explanation.

As to what you read in that book, it's absolutely accurate and their diagram looks perfect to me - the latest that H could go is 6th. That doesn't mean that H MUST be 6th, though. You're right that I COULD be after H somewhere (and I could be immediately after H, or after O, or after L, or after G - lot's of options for where I ends up).

One thing you said really stood out to me, and that is that "It is very likely that 'I' happens before 'O". Here I have to completely disagree with you, not because I cannot be before O, but because logic games do not have any element of likelihood or probability to them. There is nothing "likely" about where any variable ends up - there is only where a variable can be, where it must be, or where it cannot be. I cannot be first, because it is after K. It can be in any other position in the game because there is nothing else restricting it. It isn't "likely" to be in any particular spot - other than first, they are all equally likely because they are all just possible. H can be 4th, or 5th, or 6th, but there is nothing likely about it ending up in one of those spots over the others - they are all equally possible.

What this author was getting at was just the extreme limits for H - H cannot go any earlier than 4th, nor any later than 6th. That is true! And H could also be 5th, with either I or G after it.

I hope that helps answer your question! If not, please follow up in that other thread so that others searching for info about that game will find the discussion helpful. Thanks for your input!
