Grouping Games are about 1/3rd of LSAT Logic Games questions, so expect to get one of them on test day of the four games. Unlike Ordering Games, which require you to organize the elements or subjects of the game into either a spatial or sequential order, Grouping Games require you to divide the elements of a game into two or more groups based on a characteristic (often a team).
1. Types of Grouping Game
Put people into two or more groups and each entity is placed into one group. Like Sequencing Games, Grouping Games have only one set of variables. There are two main types of Grouping Games:
In-and-Out Games have only two options. They are like the law school admissions process; some people get in and some people don’t. There is usually a finite group of people. So, who gets in out of five people. These questions make heavy use of Conditionals, so we are going to review them in the next lesson.
- Players divided into two teams and they only play on one team.
- Items switched on or off.
Matching Games have entities assigned to multiple groups.
- Place people who can play on 2 or 3 different teams
- Assign different pieces of clothing to each person
- A banquet where each person can eat several different items
2. How to Diagram a Grouping Game
Just like in Ordering Games, you use shorthand to summarize the question’s rules. In Ordering Games we discussed The Set Up. In Grouping Games, your set up is The Grid. You’ll use The Grid to determine who is in and who is out. You go through all the entities (usually people) in the game to see if they are on the team (or group, club, etc).
You draw out The Grid to show the the traits on the left side and the top or bottom is labeled by the team or group. In the video below they call The Grid a “Grouping Board” and provide instructions for making one. Like in Ordering Games, your ability to diagram rules quickly and under pressure will play a huge role in determining your score.

Before we jump headlong into Distribution Games, we’d better take a detour into Conditionals (unless you already did). Logic Games are loaded with conditionals, especially the In-and-Out Games.
