Archive
Know the truth. Piece it together.
"You are a meticulous researcher, a consulting archivist, a field investigator. Every case is a dossier that lands on your desk—incomplete records, partial ledgers, cryptic notes from the field. Through careful reasoning, you reconstruct the complete picture that no one else could."
How to Play
Archive is a premium investigative logic puzzle. You analyze clues about categorized entities (artifacts, locations, time periods) to determine the one correct assignment through systematic elimination on a deduction grid.
