Frequently Asked Questions

The whole game builds toward one moment: the Confrontation, where you seal a vote naming the two cursed signs. Get it right and the case is solved. Get it wrong and it was, quite literally, your last deduction. Everything before that — the deaths, the reveals, the plans stated at the morning meeting — is just you deciding when you're sure enough to say it out loud.

Quick Play — the full classic game, with all thirteen entities, the All-Time Scoreboard, and persistent rival relationships — is free, forever, with no ads. Premium is a single one-time purchase. It opens Career, a ladder of authored cases with ranks, tools, and progressive difficulty, and Tournament, a bracket of thirty-two detectives. Since we don't take outside investment, show ads, or sell your data, that purchase is what keeps the lights on (dim, as intended).

Restore a purchase. On a new device, or after you install the app again: sign in to the same App Store or Google Play account that bought “Premium”, open the app, and choose restore on the screen where you bought it. The store remembers what you bought.

Ask for a refund. Refunds go through the store that took the payment:

After a refund, the app locks the item again. What you made with it stays, and comes back if you buy it again.

Scary the way a candlelit room is scary — not the way a haunted house ride is. There are no jump scares, no loud stingers, no screen shake, no strobing; the dread comes from slowness, absence, and the arithmetic of who's left. And every atmospheric effect — motion, light, fog, sound, haptics — has its own dial in settings, with a one-tap "Calm" mode that quiets everything at once. The quieter game is still the same game.

You need no account, and the game plays offline. Only the store's billing uses the network: the purchase, a restore, Google Play's check that a purchase still stands, and Google's billing logs on Android. There are no logins and no cloud saves. Your progress, Career, Bestiary, and what your rivals remember about you are all stored locally on your device.

No — they are hand-built game opponents, not language models. Nothing is generated in the cloud and nothing you do in a game is sent anywhere. Each rival is a named persona with its own deduction logic, talkativeness, and nerve. They see exactly the same evidence you do, they can solve the case without you, and they remember whether you went where you said you would.

You can — anyone may walk into the Confrontation room with no evidence at all. With fourteen signs there are ninety-one possible pairs of cursed signs, so a blind guess succeeds about 1.1% of the time. The other 98.9% of the time, you die. The game will not stop you. The game is, in fact, counting on it.

Surviving a given night involves luck — the entity kills exactly one detective, and you can't ever make yourself safe. Solving the case is skill: every death publishes evidence, every failed Confrontation rules out pairs, and a careful detective narrows ninety-one candidates to one. The real decision — and the real skill — is knowing when your evidence is worth risking another night for.

Everything stays on your device. We collect nothing, track nothing, and have no servers to send anything to. The only data that leaves your phone is whatever the app store itself handles for Premium: the purchase, a restore, and, in the first weeks after buying on Google Play, a check that the purchase still stands. On Android, Google's billing library also sends Google its own usage logs.
