Use the A Night In Derry calculator to run any visitor tip through four evidence gates. It tells you how confidently to treat the tip and returns three linked next actions — it never guesses the correct door, because no public source documents one.
Advice from other Derry, Pennywise or anomaly games can produce the wrong visitor decision.
This checklist shows how carefully to treat the clue. It does not guess the correct in-game door answer.
The checklist evaluates four conditions in a fixed order and returns at the first failure, exactly like the code that runs it. Each failed gate maps to one of five named result states.
Is the tip about this exact Roblox experience?
Place 137,635,882,679,807 by Fedora's CCU. Similarly named Derry, Pennywise and anomaly games are separate universes whose tips do not transfer — this gate exists because wrong-game advice is the single most common way players get bad door rules.
If it fails: Stop and confirm
Does the tip predate the current update?
The creator ships updates every weekend (latest Roblox timestamp: September 18, 2026, checked October 3, 2026). Horror games change their cue logic often, so an undated claim from before the last patch is treated as stale until compared.
If it fails: Recheck needed
Can the visitor cue be traced to this game?
A cue needs an exact-game origin — something you saw in the live game, or a source that names this experience and shows the result. A tip without a traceable origin cannot support a factual open-or-don't-open answer.
If it fails: Not enough information
Does the claim stay inside the documented premise?
The official description confirms visitors, trust decisions, night survival and the Clown. A claim that goes beyond that — a complete visitor roster, a guaranteed counter, a universal door rule — exceeds what any public source documents for this game.
If it fails: Claim conflict
Suppose a short clip says: "Never open the door when the clown knocks — it's always a trick." Here is what the checklist does with it, using only documented facts (checked October 3, 2026).
The same walk applies to a comment swearing a visitor is safe, or a guide swearing a counter works: the tool scores the evidence behind the claim, then hands you to the page that owns the next step.
Every run ends in one of these. None of them is a door answer — each is a verdict on the evidence.
| Result | What it means for your run |
|---|---|
| Stop and confirm | Gate 1 failed. The tip may belong to a different game entirely; confirm the experience before spending any trust on it. |
| Recheck needed | Gate 2 failed. The tip is older than the current update; compare dates before reusing it. |
| Not enough information | Gate 3 failed. The cue has no exact-game origin; keep it unresolved and play from the live prompt. |
| Claim conflict | Gate 4 failed. The claim says more than the published premise supports; treat it as commentary, not a rule. |
| Ready to prepare | All four gates passed. Act on the live prompt with the three-step preparation the tool returns for your situation. |
Result states and their order come from the tool's published logic (src/lib/door-decision.ts in this site's repository); the game facts feeding gates 1–2 are official Roblox records, October 3, 2026.
A result can point to the named Clown threat, a stale tip, or a freshness check. These pages keep each next step tied to the exact game.
No — and that is a design choice, not a missing feature. The official game documents the trust premise ("decide who to trust and survive the night") but no creator-published source documents a universal open-or-don't-open rule, so any checklist that returned one would be guessing. What it does return is how well your tip survives four evidence gates, plus the safest next action for that result.
That result means your tip failed the cue-origin gate: you cannot trace it to this exact game and its current version. A rule of thumb posted under a TikTok clip, for example, describes that clip's game version — with weekend updates, that is often weeks out of date.
"Ready to prepare" — your experience is confirmed, the update is current, the cue traces to this game, and the claim fits the published premise. Even then the final door choice stays yours: the result supports a careful next step, not a guaranteed outcome, because no public source documents per-visitor outcomes.
No. The four checks live in this browser tab only, reset with one click, and are never sent anywhere. The tool is a thinking aid for the decision in front of you, not an account system.
Whenever a visitor tip is about to influence a run — before you let a clip or comment decide a door — and again after each weekend update, since the update-freshness gate is what catches advice that a patch has retired.
