The Rules for Logic Games Rules

There are just ten days left until the February LSAT, and at this point your methods for tackling Logic Games are pretty much settled. However, there’s still time to improve your speed on this all-important section.

As you know, one of the first steps when starting a Logic Game is to visually represent each rule so that you don’t have to keep re-reading the text.

Playing the Numbers: Logic Games Superhero

Whenever I talk to people about the LSAT (which is more often than I care to admit), I almost inevitably hear the same thing: “Logic games were my favorite section.” It baffles me. Not to put too fine a point on it, but I loath logic games. I hated them when I was a student, and I continued hating them as an instructor.

Test Your Skills on the Toughest LSAT Logic Games Ever

With the October LSAT just around the corner, you should be in the refining stages for each of the three question types. This includes Logic Games, which – as perhaps the most learnable section – is a great place to invest some fine-tuning.

Once you’ve mastered the fundamentals, one great way to get prepared for LG is to challenge yourself with some of the hardest Games known to mankind. Additionally, practicing on these Games will familiarize you with the identifying characteristics of uniquely challenging games, enabling you to pick them out of the lineup on test day.

Last Minute Tips: Logic Games

With less than three weeks until the June LSAT, it’s time to buckle down on studying. This week we’re offering one important last-minute tip for each LSAT section. Yesterday we tackled Reading Comprehension; today we’re talking Logic Games.

We’ve previously discussed how to find deductions and scenarios for different Logic Games, and that’s probably the most important overall skill you’ll need in order to crush the Logic Games section. However, as we head into the final weeks before the June LSAT, there’s one relatively small tweak that could significantly help your speed and understanding of each game: Making sure that your set-up and rules are as neat, clear, and accurate as possible.

When to Write Out Logic Games Scenarios

We’ve written before about how to use scenarios to defeat certain Logic Games – essentially, when one rule leads to a limited number of possibilities for how that game can work, you’ll want to jot down each of those possibilities. But just how “limited” are we talking here?

The general rule of thumb is that if there are four or fewer possible scenarios, it’s worth your while to write ‘em out. In fact, I’d argue that – when you’re preparing for the LSAT – you should go ahead and try out scenarios if you have even the slightest suspicion that they might be useful. After all, there’s very little downside to completing scenarios, and sometimes it can lead to huge deductions. Even if you find that most or all of the scenarios are still pretty incomplete, you’d likely have to do the same work once you hit the questions, so it’s not like your wasting your time by doing that work up front.

Finding Subtle Deductions in Logic Games

Today’s post is in response to a student question about Logic Games:

Other than looking for variables in common, how can you find ways to get deductions from combining rules?

Of course, the easiest way to make deductions is to look at multiple rules covering the same variable or spot. But as the student asks, what about when that doesn’t happen? It doesn’t mean there’s nothing to be found. It’s often all about what takes up space.

In an ordering game, if there are multiple blocks, especially if they’re big, assess how they’ll fit together. Will they have to overlap? Will they get in each other’s way? Sometimes, this leads to a concrete deduction.

Defeating Tricky Logic Games Through Scenarios

It’s Saturday night and, of course, you’re taking the time to relax, kick back, and organize your action figures. You’ve got a fine collection of seven treasured man-dolls, but prized among all others are Qui Gon Jinn, Obi Wan Kenobi, young Anakin Skywalker, and Luke. Naturally you keep them in that order, to remain consistent with their apprenticeships and paternal lineage. A true thing of beauty.

But you puzzle, as you push your glasses up on your nose, how many ways you could arrange your seven total action figures, while maintaining the Force-endowed Foursome block. Naturally, you need to have Batman first and Superman last, to keep them apart and prevent them from fighting. What options does this leave you?

We’re dealing with a big block of four players, and there’s really only so many places it can go.


Tackling Overstuffed LSAT Logic Games (and Figuring Out Uber)

Our review of Logic Games continues today with an investigation into the thrilling world of Grouping Games. Specifically, Grouping Games of the overbooked variety.

Remember last weekend? When you and your buddies were trying to get home from the bars at 2 AM? You called an Uber, but in your drunken stupor you neglected to select the Uber XL. So up rolls a Prius — you could swear it’s even smaller than usual — and of course you’re left with four seats for the six of you to squeeze into. The game is overbooked. We could leave some homies curbside, but we’re feeling kind-hearted. So you’re doomed to squeeze. How could you arrange yourselves?

Let’s say the game gives these parameters:
One person immediately calls shotgun, so that’s taken, and the two who’ve been making eyes at each other throughout the evening all-too-eagerly offer to sit lapsies in the far left bench seat.

LSAT Logic Games: How to Use ‘But Not Both’

In Logic Games, cute and cuddly “A must come before B” rules are often treated as cherished instructions. It makes sense; they’re simple, absolute, and easily diagrammed. They’re also more intuitively digestible than some of our more complex Logic Games rules.

But digesting complex carbs gives you fuel, while simple carbs give you a beer belly. Similarly, complex LG rules often unlock the game and propel you through the questions, whereas “A before B” rules… make you fat… (shush, no analogy is perfect).

One of the most useful complex relationships comes in the form of an exclusive disjunction. You remember these from Logical Reasoning: “Bubba buys either laundry detergent or a whole new wardrobe, but not both.”

It’s Elementary: Two Steps To Find Deductions in Logic Games

If you’ve spent any length of time studying the Logic Games section of the LSAT, you’ve probably realized that deductions (or inferences, as you may call them) can make or break a game. Sometimes they’ll simply help you get through a game more quickly; sometimes you won’t even be able to answer a question without having caught the deduction.

So deductions are, to put it lightly, important. Unfortunately, they can also be tricky to spot. When working through a game, after building the setup and representing rules, here are a couple of good areas to start your search for deductions.
