Game Set Up Different Than Video

In the game set up video the process is writing down the rules and creating the major/main chain for the sequence. The step of writing out nine blank spaces with your deductions as you go through each of the rules was omitted; however, in both practice games in the lesson video she takes the time to complete this step. Based on the lesson video I too did this step which took me considerably more time than as shown in the game set up video. Thus, I am confused as to how to know when I do or do not need to take the step of writing my deductions. Why did she skip this step in the video / how did she know to skip this step to save time?

After some reflecting - is the reason she skips diagraming nine spots and writing deductions because the rules due to the fact the prompt does not say its a one to one relationship between person and salary ranking?

Great question. I'm not sure why she left it out in one of the
explanations, but I think that the easiest way to set this game up is
by making a 9-slot sequence to show where the partners can go.

_ _ _ _ _ _ _ _ _
1 2 3 4 5 6 7 8 9

K goes in 1

K _ _ _ _ _ _ _ _
1 2 3 4 5 6 7 8 9

We then have the two chains

L - N

I - F - M - G - J - H

Note that the two chains are independent; we just need to make sure
that the sequence within each chain is satisfied and we're good to go.

With that general setup, you can fly through the questions pretty quickly.

Does this make sense? Let us know if you have any other questions!
