Introduction
Sequencing Games are the most common game type in the LSAT Analytical Reasoning (Logic Games) section, historically comprising approximately 35 percent of all legacy Analytical Reasoning games. These games present a set of elements that must be arranged in a linear order subject to a series of rules. The task is pure order determination: given the constraints, figure out what can and cannot be true about the relative or absolute positions of elements.
The 21 topics in this unit cover the complete sequencing game system: basic sequencing game structure, strict versus loose sequencing, rule types (before-and-after rules, block rules, adjacent rules, not-adjacent rules, ordering rules, relative ordering), rule diagramming conventions, sequencing game setup procedures, deduction strategies, template and scenario approaches, limited-solution sets, common question types (could be true, must be true, cannot be true, inference, substitution), and the specific strategies for each question type.
The core competency this unit develops is efficient constraint management: holding multiple rules in a single coherent diagram that reveals which configurations are possible and which are not. Students who can set up sequencing games quickly and derive deductions early will handle even the hardest sequencing questions in under 7 minutes.
Learning Objectives
- Construct an accurate master diagram representing all sequencing game constraints using standard symbolic notation.
- Translate verbal rule statements into symbolic notation: before-and-after (X before Y: X...Y), block rules (XY), not-adjacent (X/Y), absolute position (X is third: X=3).
- Derive valid deductions by combining rules: identify forced placements, identify restricted positions, and identify floating elements.
- Distinguish strict sequencing (elements fill consecutive slots) from loose sequencing (elements are in relative order but not necessarily adjacent).
- Identify when limited solution sets or templates are useful and construct them efficiently.
- Apply systematic question strategies: acceptability questions (check each rule against each answer), conditional questions (add the new information and derive consequences), must-be-true questions (find what every valid arrangement shares).
- Recognize and avoid common sequencing traps: conflating "before" with "immediately before," misinterpreting relative ordering as absolute positioning, and missing deductions from combined rules.
High-Yield Concepts
| Rule Type | Verbal Form | Standard Diagram |
|---|---|---|
| Before/After | X is before Y (not necessarily adjacent) | X...Y |
| Immediately before | X is immediately before Y | XY (block) |
| Block | X and Y are consecutive in that order | XY |
| Not adjacent | X and Y are not next to each other | X /adj Y |
| Absolute position | X is in position 3 | X=3 |
| Relative ordering chain | X before Y before Z | X...Y...Z |
| Conditional placement | If X is in position 3, then Y is before Z | X=3 -> Y...Z |
| Question Type | Strategy |
|---|---|
| Acceptability (which could be a valid arrangement?) | Check each rule against each answer; eliminate any answer violating a rule |
| Must be true | Find what holds in every valid arrangement; test by trying to violate it |
| Could be true | Find at least one valid arrangement where the claim holds |
| Cannot be true | Find why every arrangement where the claim holds violates a rule |
| Conditional (if X is in position 3, which must be true?) | Add the new condition, derive new deductions, then answer the question |
| Substitution (if rule 3 is replaced, which has the same effect?) | Determine what rule 3 prohibits; find the answer that prohibits the same configurations |
Always do the setup before attempting any questions. Spend the first 2 to 3 minutes on every game constructing the master diagram, noting rule interactions, and deriving deductions. Students who skip setup and jump directly to questions spend more time overall because they repeat the same reasoning for each question. Setup is an investment that pays dividends across all 5 to 6 questions in the game.
Study Strategy
Begin with basic sequencing games and master the standard rule types and their diagrams before moving to advanced topics like loose sequencing or limited solution sets.
Drill rule translation until it is automatic. The ability to quickly and accurately convert verbal rules into symbolic notation is the primary mechanical skill for logic games. Errors at this step propagate through everything that follows.
Study the deduction process as a systematic procedure: (1) Look for rules that share a term (same element appears in two rules). (2) Combine those rules to derive new constraints. (3) Identify the most restricted element (the one with the most constraints). (4) Look for forced placements (an element that can only go in one or two positions). (5) Check for limited solution sets.
Practice template construction for games where one element is highly restricted. If an element can only be in positions 2, 3, or 4, build three templates (one for each possibility) and eliminate the ones that violate other rules. The remaining templates exhaust all valid arrangements.
Think of sequencing rules as a network of ropes connecting elements. Each rule is a rope that restricts relative movement. The more ropes, the less freedom each element has. Your job is to pull all the ropes tight at once and see what positions remain possible. The most restricted node in the network reveals the most about the entire arrangement.
Common Mistakes
Treating "before" as "immediately before." "X is before Y" means X is somewhere earlier in the sequence than Y, not that X is in the slot immediately preceding Y. "X is immediately before Y" is a block rule (XY). Confusing these two rules is one of the most frequent sequencing errors.
Missing deductions from combined rules. Many students look at each rule in isolation without combining them. If rules say X is before Y and Y is before Z, the combined deduction X...Y...Z is obvious, but if the rules are in a different order or phrased differently, students miss the chain.
Creating overly elaborate initial diagrams. Over-diagramming early wastes time. Note what is known, derive what is derivable, and leave unknowns as unknowns. The diagrams for specific questions should be built on the master diagram, not recreated from scratch.
Forgetting to verify acceptability answers against all rules. On acceptability questions, check every rule against every answer. Students who check two or three rules and then guess often miss a violation in the rule they did not check.
Exam Tips
On conditional questions (if X is in position 3, then...), draw a new mini-diagram with the new condition added. Derive all deductions from the combined constraints. Then answer the question from the mini-diagram. Do not guess from the general setup.
For substitution questions (which rule could replace rule 3 with the same effect?), first determine precisely what rule 3 prohibits. The correct substitution must prohibit exactly the same configurations and no others. Substitution wrong answers often prohibit more or fewer configurations than the original rule.
Identify whether a game has a "limited solution set" (a small number of total valid arrangements) during setup. If after applying rules you find only 3 to 4 valid arrangements, mapping them all explicitly is faster than working each question from scratch.
Do not place a conditional deduction in your master diagram as if it were an unconditional constraint. If "If X is first, then Y is last" is a rule, you cannot place Y last in your master diagram; that placement only holds when X is first. Keep conditional constraints conditional and use them only when their condition is activated by a question's new information.
