Description

--- **The Search for Planet X** is a competitive deduction game simulating astronomical discovery, where players use logic and app scans to locate a hidden planet amid orbiting objects. Key mechanics include: - *App-generated board* Companion app randomly arranges objects and Planet X location per game using logic rules. - *Scanning and conferences* Players perform app-based scans and attend conferences each round to reveal object positions. - *Deduction sheets* Mark gathered data to logically narrow possible locations for objects and Planet X. - *Theory publishing* Score points by proposing and confirming object locations as information accumulates. - *Planet search* Submit precise guesses via app; successful find ends game with final scoring opportunity. The Search for Planet X is a puzzle-driven board game where players embody astronomers hunting a hypothetical Planet X at the solar system's edge, mirroring real 2015 orbital anomaly theories. A companion app establishes unique object arrangements and Planet X's position each session. Over rounds synced to Earth's orbit, players acquire data through scans and conferences, annotating deduction sheets to deduce positions. Progressive revelations enable theory publication for points, refining Planet X candidates. Culminating in app-verified searches requiring exact location and flanking objects, the first success triggers game end and bonus scoring, embodying scientific thrill, investigative logic, and rivalry. ---
