At the edge of our solar system, a dark planet may lurk. In 2015, astronomers estimated a large distant planet could explain the unique orbits of dwarf planets and other objects. Since then, astronomers have been scanning the sky, hoping to find this planet.
In The Search for Planet X, players take on the role of astronomers who use observations and logical deductions to search for this hypothetical planet. Each game, the companion app randomly selects an arrangement of objects and a location for Planet X following predefined logic rules.
Each round, as the earth travels around the sun, players use the app to perform scans and attend conferences. As they gain information about the location of the objects, they mark that information on their deduction sheets. As players learn the locations of the various objects, they can start publishing theories, which is how players score points.
As more and more objects are found, players narrow down the possible locations for Planet X. Once a player believes they know its location and the objects on either side of it, they use the app to conduct a search. The game ends when a player successfully locates Planet X, and all players have a final chance to score some additional points.
The Search for Planet X captures the thrill of discovery, the puzzle-y nature of astronomical investigation, and the competition inherent in the scientific process. Can you be the first to find Planet X?

An app-driven deduction puzzle that will tickle your logic bone! As a thematic exploration of the stars, Search for Planet X has a relatively low rules overhead. Player actions reveal and narrow down what's in the sky while also learning game-specific rules. As a logic puzzle, it can sometimes devolve into a solitary affair, however there is actually some clever indirect player interaction here. When noting other players' actions, a player might be able to infer objects in sectors or piggyback on research papers. Most importantly, I think Search for Planet X empowers the player by giving enough tools and starting (and adjustable) advantages to make smart inferences. It's my evergreen puzzle game that is easy to table when everyone is feeling up for a brainy race of deductions.

A great deduction game with a great theme. It make you feel that you really act like an astronomer. Very thematic with different layers of deduction based on the information the app told you and the action done by other players. Definitely is one of the best game in 2020.

+ An intriguing logic puzzle develops naturally as you uncover specifics and additional game rules through the conferences; You feel the push to maximize each data grab because of the other players around the table. - I don't love that you have to use an app for each player in the game (or pass a phone around), but that is what makes a game like this possible without a dedicated game manager person I suppose. Why it's previously-owned: It is a tremendous logic puzzle, and I actually really like it for that. But that is not really why most of the people I game with like to game. Theme is the single connecting theme of most of our favorites, and thematic, this is not.
