The central HOUSE 13 decision is whether the stranger asking to enter is a person in need or an Impostor. The official description says Impostors take human shape, wear human clothes, and imitate human voices. That makes a single “looks normal” check inadequate. Use every observation and question the current run provides, compare the evidence, and make one deliberate admit-or-refuse decision.
The five-step visitor check
First, establish the context shown by the current run: who is at the door, what the emergency broadcast or interface has already told you, and which mode you selected. Second, observe before interacting. Look at the full presentation rather than fixing on one detail. Third, use each available question or inspection option in a consistent order. Fourth, compare answers, voice, and appearance with facts the game itself has shown. Fifth, state the reason before acting so a squad can catch a missed contradiction.
The exact prompts, visitor roster, correct answers, and randomization rules are not published in first-party text. That means this guide does not label an unsupported face or name as always human or always an Impostor. If an older video and the live server disagree, the live evidence wins.
Build an evidence stack
Appearance
Check clothing, proportions, movement, and visible details the game presents.
Limit: appearance alone cannot prove humanity because the official description says Impostors copy shape and clothes.
Voice
Listen for what is said and how it matches the current situation.
Limit: voice alone is not decisive because imitation is explicitly part of the premise.
Answers
Use all current questions and compare replies for contradictions or missing context.
Limit: no complete official answer key was available for this check.
Run context
Use information already revealed during the same session and mode.
Limit: do not import Terminal 13 passport, item, or NPC rules into HOUSE 13.
Make a squad decision without chaos
Choose one caller before the first knock. Other players report observations, not votes. The caller repeats the strongest evidence and makes the final decision. If someone disagrees, they name the contradictory clue before the action, not after the door opens. This prevents the loudest player from replacing the actual inspection process.
Keep one player watching the house while the caller studies a stranger. The Reacher, Hitcher, and Nester have separate location-based responses, and a group can still fail while making a careful door decision. Use short callouts that include location: front window, darkness in hall, closet occupied, room claimed.
After the decision, record the result. If the game reveals whether the choice was correct, connect that result to the complete evidence stack—not only the last detail someone noticed. A correct guess based on one feature can teach a false rule that fails on the next visitor.
Show Impostors gamepass
HOUSE 13 sells an official Show Impostors gamepass, ID 1969402471. Its description says it points out Impostors pretending to be human. The product was listed at 159 Robux on September 13, 2026. That confirms the purpose, but not the marker’s appearance, timing, coverage, team visibility, mode restrictions, or effect on endings.
If you own it, record when the indicator appears and who can see it. Do not assume a teammate receives the same information. Use the pass as decision assistance, not proof that house threats are disabled. The Show Impostors guide covers the buying questions that the short store description leaves open.
Common bad rules
“Familiar face means human”
The official premise specifically allows copied human shape and clothes. Familiarity is a reason to compare more carefully, not an automatic admit.
“Normal voice means human”
Imitated voices are also official. Listen for consistency with the current answers and context.
“A video answer never changes”
Public walkthroughs document one version and run. Visitors, prompts, or outcomes may change or randomize.
“Terminal 13 rules apply”
The games share an official story relationship, but HOUSE 13 does not inherit the other experience's passport, item, or NPC mechanics by default.
Recover after a wrong choice
Write down the visitor, mode, exact questions, answers, observations, decision, and displayed result. On the next comparable encounter, change the conclusion only if the evidence supports it. If several details were missed, improve the inspection order before adding a new universal rule.
Do not publish a complete visitor table from one run. A reliable index needs the current version, repeated encounters, evidence of randomization, and a clear outcome. Until then, keep entries as session notes and use them to ask better questions rather than telling every player a fixed answer.
Balance help and challenge
Some players want the deduction tension; others want to see the story or complete a long mode with fewer uncertain calls. A normal run teaches the intended evidence loop. Show Impostors may suit a player whose main goal is completion or accessibility, but its exact effect should be checked in the live game before purchase.
