Requires reaching the True Ending within 10 total loops. This is only achievable on a second or subsequent playthrough with full case knowledge. Use the critical path from the Tips & Tricks guide — 3-loop minimum path gives you 7 loops of buffer. This achievement and Hasty Judgment are the only two that require deliberate planning around loop count.
The game contains several dialogue lines that are direct references to Machado de Assis's works beyond Memórias Póstumas de Brás Cubas. These include references to Dom Casmurro and Quincas Borba. The Easter egg achievements are triggered by selecting specific dialogue options that reference these works when speaking to Brás Cubas's ghost directly. By Loop 31 you will have encountered these options — if not, revisit the ghost dialogue with maximum knowledge state active.
Track your progress through all remaining achievements. For full details on every achievement, see the All 28 Achievements guide.
Loop 38 is the final cleanup loop. Open the achievement list before starting and note any unchecked items. Route the loop to collect any remaining triggers in a single run. The 100% completion achievement (Full Case Closed) triggers automatically when the last achievement in the list is unlocked — it does not require submitting a final accusation.
