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.

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.

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.”
