The Search for Planet X

The Search for Planet X is a competitive logic deduction game where players act as astronomers trying to locate a hidden planet at the edge of the solar system.

Each game, a companion app secretly determines the positions of celestial objects—like asteroids, comets, and gas clouds—along with Planet X itself. Players then use actions like scanning sectors, surveying regions, and researching rules to gather information and eliminate possibilities.

The puzzle works almost like Sudoku in space. You’re not guessing—you’re logically narrowing down possibilities using known rules about how objects can and cannot be arranged.

As players gain confidence, they can publish theories for points or attempt to locate Planet X. Finding it can trigger the end of the game, but you’ll still need to have your deductions right to win.
