01The core loop

Action → feedback → next choice
  1. 01Survey the frozen scene
  2. 02Collect names and details
  3. 03Fill in conclusions
  4. 04Confirm in batches

↻Feedback changes the situation — the next round starts from there.

Walk through one round

A simplified design example. Situations and numbers illustrate the mechanic, not exact rules from a reference game.

  1. T1

    Turn 1 · The situation

    Three bodies in a cabin; you've identified only one.

  2. T2

    Turn 2 · The player chooses

    Use hammock numbers and uniform details to name the other two as sailor and cook.

  3. T3

    Turn 3 · The feedback

    All three identities and causes are correct and the set locks in.

  4. T4

    Turn 4 · The next decision

    The cook's name points to a clue in the next scene.

How it plays

Players freely inspect people, objects and text in a frozen scene, then fill in who did what to whom with what. The game confirms only when a full group is correct, blocking brute force and demanding complete reasoning.

What the player weighs

  • Submit partial answers or keep investigating
  • Go with the obvious clue or doubt the surface

03One mechanic, different implementations

Return of the Obra Dinn
R

Return of the Obra Dinn

P1

A pocket watch takes you into frozen death scenes to deduce the identity and fate of dozens of crew, with confirmations arriving every three correct.

The Case of the Golden Idol
C

The Case of the Golden Idol

P2

Players collect words from frozen scenes and drag them into fill-in-the-blank sentences to rebuild events and identities.

The difference worth noticing

Obra Dinn is one long mystery around a ship; Golden Idol is a series of separate cases solved through word-fill reasoning.

Case notes are Yoroll editorial summaries; rules may change between versions.
