It’s an ugly, rainy, windy day in Washington and all of my lessons are canceled. I’m going to dig into 10 New Actual, Official LSAT PrepTests and do a logic game to pass the time. Let’s try PrepTest 57, Section 1, Questions 1-5 (10 New LSAT, page 188).
This looks like a relatively straightforward ordering game. The items are G, H, J, K, L, and M. I’ll shorthand the rules as follows:
(1) HG
(2) K-G
(3) M-L
(4) JM or MJ
The repetitions of G between rules 1 and 2 and M between rules 3 and 4 are surely not accidental.

Building off the formal logic posts of the last two weeks, today we’re going to discuss the LSAT logic game found at PrepTest 58, Section 3, Questions 7-12 (10 New LSAT, page 241).
This is a fairly simple In-and-Out game (also known as a Selection game). Such games often involve heavy doses of arrow diagramming, and this one is no exception. Take a quick read of the setup and then let’s turn our attention to the rules.
The rules of this game can be diagrammed in straightforward fashion as follows:
1. R→M
2. M→T
3. !S→V
4. !R→L
5. T→(!F and !V)
Let’s turn to the questions now.
