Procedural Challenges
The game does not always ask a question.
Procedural challenges are generated at play time and scale with the current level. Historical content remains curated; the generator changes the puzzle structure, combination, and difficulty.
Spot the Differences
Compare evidence scenes and identify meaningful changes.
Reconstruct
Choose the components needed to rebuild an object or toolkit.
Put Events in Order
Reconstruct chronological or technical sequences.
Match Evidence to Activity
Connect archaeological traces to the actions that most likely produced them.
Logic Puzzle
Use a set of clues to reach one unique solution.
Find the Anachronism
Spot objects that do not belong in the historical period.
Contextual Maze
Navigate historically framed routes with tighter limits at higher levels.
Investigation Scene
Select the clues that support a specific activity or interpretation.
Final Investigation
Earn the case.
Era I · Final Case
The Last Ember
A storm has nearly put out the campfire. By dawn, a protected ember is missing. Examine four locations, compare twelve clues, reconstruct WHO, WHY, WHERE, WHAT, and WHEN, then choose the three pieces of evidence that prove your theory.
Theory: 5/5 required
Evidence: 3/3 required
English is the default language of the game. Additional language packs are being designed around stable question, option, evidence, and progress IDs so changing language will not reset progress.
