Linear games single column
59 flashcards covering Linear games single column for the LSAT Logic Games section.
Linear games in a single column involve arranging items in a straight sequence, such as ordering people in a line or scheduling events one after another. In these games, you work with rules that dictate the order, like "A must come before B," and use them to figure out possible arrangements or answer questions about positions. This setup tests your ability to handle logical sequencing, which is a foundational skill for more complex problems.
On the LSAT, single column linear games appear in the Logic Games section, often as questions asking what must be true, could be true, or cannot be true based on the rules. Common traps include overlooking subtle conditions or assuming extra constraints not stated, which can lead to incorrect deductions. Focus on accurately diagramming the sequence and practicing how rules interact to build efficient strategies for these questions.
Always start by drawing a clear line for the sequence.

Floating Entity
An entity in a linear game that is not constrained by rules and can be placed in multiple positions, adding flexibility to the sequence.
- 13
Must Be First Rule
A rule requiring an entity to occupy the initial position in the line, which often leads to further deductions about other entities.
- 14
Must Be Last Rule
A rule that places an entity at the end of the sequence, influencing the arrangement of preceding items.
- 15
Not Before Rule
A rule stating that one entity cannot precede another, meaning the second must come earlier or they might be equal in some contexts.
- 16
Not After Rule
A rule indicating that an entity cannot follow another, so it must either precede it or be in a position that satisfies the constraint.
- 17
Immediately Before Rule
A rule that requires one entity to be directly ahead of another in the sequence, with no entities in between.
- 18
Immediately After Rule
A rule mandating that one entity must follow directly after another, creating a tight block in the line.
- 19
Block of Entities
A group of entities that must stay together in a specific order due to rules, treated as a single unit in the sequence.
- 20
Unconstrained Entity
An entity with no rules affecting its position, allowing it to be placed freely as long as other constraints are met.
- 21
Overlapping Rules
Situations where multiple rules interact, potentially creating more restrictions or deductions in the linear arrangement.
- 22
Partial Ordering
A state in a linear game where not all entities have a fixed order, leaving some flexibility until further deductions are made.
- 23
Complete Ordering
The final arrangement where every entity has a determined position based on all rules and deductions.
- 24
Common Trap: Assuming Symmetry
A frequent error where test-takers assume rules apply equally in both directions, such as thinking 'A before B' implies 'B after A' without confirmation.
- 25
Identifying Inferences
The skill of drawing logical conclusions from rules, like inferring that if A is before B and B before C, then A is before C.
- 26
Using Arrows in Diagrams
A diagramming method where arrows indicate directionality, such as an arrow from A to B meaning A before B.
- 27
Strategy for Multiple Rules
A approach to handle several rules by prioritizing those that fix positions or create blocks, then addressing the rest.
- 28
Error in Rule Application
A mistake where a rule is misapplied, such as confusing 'before' with 'immediately before,' leading to incorrect diagrams.
- 29
Maximizing Flexibility
A technique to place unconstrained entities in ways that keep options open, avoiding premature commitments in the sequence.

Minimizing Possibilities
The process of using rules to eliminate invalid arrangements, narrowing down to only those that satisfy all constraints.

How rules overlap in a diagram, potentially creating cycles or dead ends that must be resolved.
