How to Diagram Common LSAT Logic Games

Update: Taking the LSAT in August 2024 or later?  Be sure you know about major upcoming changes to the test and plan accordingly.  In particular, the Analytical Reasoning section (aka Logic Games) will be removed, and there will be a new argumentative task in the Writing section. Taking a test prior to August 2024? Read on!

Timing on the LSAT test is meant to be challenging, and nowhere is it more so than in the Logic Games (Analytical Reasoning) section. This is probably the single place where the most time is wasted on the LSAT. To help you get a handle on this section, we’ll show you how to identify the common LSAT Logic Games and complete the basic diagrams associated with each game type.

How to diagram an LSAT Logic Game

A few common game types appear over and over again on the LSAT:

  • Sequencing games,
  • Grouping games
  • Matching games

Each of these game types has a standard diagram that will allow you to keep track of rules and possible solutions. Any LSAT prep book, course, or tutor will introduce you to some version of these diagrams because they are critical to your success.

Find diagrams that you’re comfortable with, and memorize them. As soon as you understand what a game is asking you to do, start drawing the appropriate diagram clearly and neatly on the page beneath the game setup. Always try to keep your diagram as simple as possible!

Separate your master diagram from your question diagrams

Learn how to separate your master diagram

Your master diagram should be built exclusively from information provided in the game setup and the rules. Label it clearly as “Master Diagram” and keep it separated from the individual question diagrams.

Many questions will provide additional information that can be drawn into a question-specific diagram. Question-specific diagrams are simply master diagrams with new information added. Label them clearly with the question number they represent and try to draw them as close to the applicable question as possible.

Separating your diagrams and labeling them clearly is helpful for two reasons. First, it prevents you from accidentally applying information from one question to another question where it doesn’t belong. Second, it allows you to keep track of deductions you’ve made in previous questions, and then use those same deductions to answer later questions more quickly. (You don’t want to miss a point because you looked at the wrong diagram!)

Now, let’s jump to another fun part of Logic Games – Formal Logic!

Know your formal logic

Learn more about formal logic

Formal logic appears in most, if not all, Logic Games—most often in the form of if/then, only if, if and only if, or unless statements. Knowing the nuanced differences between these types of statements will help you interpret rules and draw diagrams more accurately.

In fact, familiarity with formal logic is probably the single most valuable tool on the LSAT Logic Games section. Also, knowing formal logic will improve not only your Logic Games score, but also, your Logical Reasoning score. And who doesn’t want that? So, be sure to review Magoosh’s posts on formal logic: If, Only if, and If and Only If on the LSAT, and If/Then Statements and Contrapositives.

Draw out limited options

Read our tips about limited options

If you notice a particular rule or piece of information introduced in a question restricts the number of possible solutions to only 2 or 3, draw each one out completely. For example, if your task is to arrange guests around a table, and a rule tells you that Bob must sit next to Francine, that leaves only two possibilities. In the first, Bob sits immediately to the left of Francine. In the second, Bob sits immediately to the right of Francine. Rather than trying to remember that fact, draw two tables and place Bob and Francine at each based on the two possibilities. This simple step will save you a lot of time and help you get more points!

Once you’ve drawn out these limited options, make sure to incorporate all the other rules into each option. You’ll often find you now have enough information to fill in most—if not all—of at least one of the options. As a result, the related questions will likely be very easy to answer. And who doesn’t want a few easy LSAT questions?

Types of LSAT Logic Games

Now, let’s dig into the more common Logic Games and help you take your skills to the next level!

LSAT Sequencing games

Sequencing games are the most common LSAT Logic Games. The good news? They are often the easiest! You might want to start each Logic Games section by searching through the four games and trying to spot a Sequencing game. If you see one, do it first. That’s a nice way to pick up 5-7 points quickly while building your confidence!

How to spot a Sequencing game

Sequencing games have only one set of variables and one set of ordered spaces in which to place them. Variables refers to the made-up names that all start with a different letter and aren’t inherently ordered. For example, numbers, days of the week, or months of the year are inherently ordered, while people and events are not inherently ordered.

A great way to quickly identify a Sequencing game is to look for the ratio of spaces to variables. Anything with a 1:1 ratio of variables to spaces is Sequencing. For example, if there are 6 trains arriving at 6 different times, it’s a Sequencing game. Rarely, there’ll be one extra variable and you’ll be required to assign two variables to one space. That’s still Sequencing, and you can just treat that space as divided into two sub-spaces.

How to diagram a Sequencing game

Since all you’re doing is putting things in order, you simply need to draw out your spaces in a line and label them clearly. List out your variables somewhere nearby, and you’re ready to start working through the rules.

Here’s an example of how to diagram a student’s class schedule if we know the student is taking 7 courses, and that they’re Algebra, Biology, English, History, Political Science, Psychology, and Water Polo.

LSAT Grouping Games

Grouping games are the second most common LSAT Logic Games. Like the other game types, they vary in difficulty from very easy to very difficult. However, diagramming a Grouping game is fairly easy, so try to complete these games early to pick up a few points!

Like Sequencing games, Grouping games have only one set of variables. Unlike Sequencing games, Grouping games do not have a 1:1 ratio of variables to available spaces. Instead, they provide you with only 2 or 3 categories where your variables will be placed.

Most of the time these categories are obvious. You’re asked to place people on 2 or 3 different teams or pay bills on 2 or 3 different days of the week. On rare occasions, though, you’re given a scenario where you have to select some variables but not others. Don’t be fooled! This is just a Grouping game with 2 categories: one that includes the variables and one that doesn’t.

How to diagram a Grouping game

All Grouping games have the same basic diagram, which is just a set of labeled categories like the one below.

But you won’t stop there, since the game will always provide you with more information that can be incorporated into your diagram before you even get to the rules. There are two common types of Grouping games, Fixed and Floating, and each has its own special details in the diagram.

In a Fixed Grouping game, the setup tells you exactly how many variables will be assigned to each group. In this case, you represent those variables by drawing the appropriate number of slots in each category. Your sketch will look something like this:

In a Floating Grouping game, you won’t necessarily know how many variables go in each category. However, there are usually some hints as to the minimum or maximum number that can be assigned to any given category. So, you can draw slots where appropriate and use question marks to represent places where variables may or may not be assigned.

LSAT Matching Games

Matching games are not very common on the LSAT, but they appear often enough that it’s worth knowing how to identify and diagram them. While some Matching games can be quick and easy once you’ve mastered the basic diagram, most of them tend to be time-consuming since the diagram usually takes more time to draw.

If you spot a Matching game, it might be a good one to skip and return to once you’ve picked up some points on the Sequencing and Grouping games. But let’s make sure you get some points on Matching games, too!

How to spot and diagram an LSAT Matching game

Matching Games always contain two different sets of variables (for example, people and pets, or shirts and pants), but they do not contain any ordered spaces. You’ll be asked to pair the sets of variables with each other, but you won’t be required to arrange them in a particular order.

How to diagram an LSAT Matching game

The key to diagramming a Matching game is to set up a table. List one set of variables vertically and list the other set horizontally, creating a grid of boxes in which you can place an “X” or a check mark to indicate whether or not a particular pairing is selected. That’s about all there is to it!


The trick with mastering Matching games is not in setting up the basic diagram, but in building rules and inferences into it.

Quick tip: pay attention to whether each variable can be used once or more than once. If a variable can only be used once, then you can places Xes in its entire row or column as soon as you’ve placed at least one check mark in that row or column. However, if the variable can be used multiple times, you lose that advantage.

Be sure to practice Matching games so you can grab these points on test day!

LSAT Hybrid Games

Now that you’ve got the basic Logic Game types down, let’s dive into the hybrid game types. Hybrid games incorporate two of the tasks discussed above, like matching and sequencing, into one game.

LSAT Sequencing/Matching Hybrid Games

Lots of people shudder at the thought of hybrid games, but remember, once you’re familiar with their common forms, they’re not too difficult. Sequencing/Matching hybrids are relatively common LSAT Logic Games, and while they can vary in difficulty, they’re easy to set up.

Like Matching games, Sequencing/Matching hybrids will have two sets of variables. But they require you to place the sets of variables in order. For example, they might ask you to schedule speakers in a lecture series, and then assign each speaker an auditorium in which to present. Often one set of variables will contain fewer items than the other set, meaning that at least some items in the smaller set will have to be used multiple times.

How to diagram a Sequencing/Matching Hybrid game

A common mistake test-takers make is to attempt to set these up as regular Matching games using a grid. But because the grid doesn’t allow you to represent order, you end up struggling more than you have to.

In a Sequencing/Matching hybrid, I’d recommend representing the sequencing component horizontally, like you would a timeline. In other words, start with a Sequencing diagram, and build from there.

First, you set out your row of spaces to house the first set of variables (this should be the larger set if they are different sizes; otherwise, it probably doesn’t matter which one goes first). Then, you simply duplicate that with another row of spaces directly beneath it, where you’ll place the second set of variables. If two variables from different sets are paired together, then they should occupy spaces directly above/below one another.


Once you have this basic setup, you can start working through the rules. The rules may refer to either set of variables. But don’t worry—you’re prepared to handle that because you can place members from each set in their respective row, wherever the rule stipulates they should go.

Great job with your first hybrid game type!

Let’s take a look at another hybrid game you’re likely to see on the LSAT.

LSAT Grouping/Sequencing Hybrid Games

This is the other common LSAT Logic Games hybrid. Like the previous hybrid, Grouping/Sequencing hybrids can vary widely in difficulty. They can also be a little tricky to set up at times, so this would be a game you’d want to leave for the end.

Grouping/Sequencing hybrids will contain only one set of variables, but you will be asked to place those variables into groups, some or all of which may have internal order. For example, you may have to schedule which movies play at a theater on Friday, Saturday, and Sunday (so you have 3 categories), and then determine when each movie will play (at 7pm, 9pm, or 11pm).

As with regular Grouping games, it’s possible to have either a fixed or floating element, meaning you may or may not know how many variables are assigned to each category. That’s why these games can be tricky to diagram. But don’t worry. We’ve got you covered—read on for tips on diagramming this game type.

The Grouping action will almost always be the first action in a Grouping/Sequencing game. You could be asked to arrange items and then group them (an example would be determining the order of lectures and then deciding how many are scheduled in the morning and how many in the evening), but that’s uncommon. In a grouping/sequencing game, start with a standard Grouping diagram of categories. Then, you can build internal order vertically or horizontally (whichever you prefer) in each category.

Whew, that’s a lot of information. But you can see from the sketch below that the diagram will still be pretty simple!


When it’s a fixed grouping game, it’s pretty easy to draw the exact number of slots you need and label each clearly. If it’s a floating grouping game, you may need to use some question marks again to denote what you do and don’t know. Either way, practice makes perfect so be sure to practice lots of hybrid games.

Now, let’s look switch gears a bit and look at uncommon LSAT games.

Rare Logic Games

For the most part, you’re only going to see the most common Logic Games on the day of the LSAT. However, some uncommon games have been making an appearance on recent exams.

In the event you find yourself looking at a totally different type of game, don’t worry! We’re going to walk through one of these uncommon Logic Game types, so you know how to approach this game type and any other game the LSAC throws at you on test day.

Mapping Games

These tough games made an appearance in 2014 after more than a decade in hiding. A mapping game will give you information about a subway system or train schedule, and you have to design the map based on the information given.

The trick, as always, is to stay calm and remember what you know. You already have a tried and true method for approaching Logic Games, so stick with it. Use your formal logic and diagramming skills to work through the information presented.

And remember, your goal is still to turn the information presented into a solid sketch to tackle the problems, pick up points, and move on!

You’ve got to be prepared for anything on the day of the LSAT. If you see a game setup you’ve never seen before, don’t panic. Save the uncommon game for last; go get those other points on the games you know well. Then, go back and work through the uncommon game just like you would any other game. Organize the information using the formal logic you’ve learned and move on to the questions.

Diagramming LSAT Logic Games: A Quick Recap

There are really only 5 common LSAT Logic Games for which you need to be prepared. Of course, LSAC can throw us a curveball now and then in the form of a rare game type, but the chances are slim and the time it would take to prepare for all of those possibilities is probably not worth the investment. To best prepare for a rare game type, your best bet is just regular practice. The more comfortable you are with the principles of organizing data, the better you’ll perform when you have to come up with your own organizational strategy.
