Since 2016, astronomers have been searching for a large, distant planet to explain the unique orbits of objects in our solar system. In THE SEARCH FOR PLANET X, a tabletop board game from Foxtrot Games, you will take on the role of these astronomers, using observations and logical deductions to search for this distant planet. The game uses a companion app to randomly choose a location for Planet X and other objects, following predefined logic rules. As the earth travels around the sun, you will interact with the app to perform various research actions. You'll note what you learn on your deduction sheet, and you'll be able to piece together all the available information to publish theories and score points. THE SEARCH FOR PLANET X captures the thrill of discovery, the puzzly-nature of astronomical investigation, and the competition inherent in the scientific process. ## Key features - Simulates astronomical investigation - Uses logical deductions - Randomly generates game elements - Companion to a tabletop board game - Tracks player progress and theories ## Recent user reviews (10 of 10) All indexed reviews: https://appshunter.io/ios/app/the-search-for-planet-x/id1456596104/reviews.md ### 1/5 — Cannot Silence *2024-02-18, version 2.5.2* There don’t seem to be any settings for the app, to disable sound. Worse, it somehow manages to play sounds even if I physically silence my phone! How is that even possible? ### 5/5 — Great game *2023-09-09, version 2.5.2* My and my grandma love playing this game and it is super fun ### 2/5 — Pointless app *2022-06-08, version 2.3.1* The app doesn’t keep track of turns or play for the AI in single player. I’m not even sure why they decided to make an app for this game, honestly. ### 5/5 — Works fine, but the bot is hard to beat. *2022-04-02, version 2.3.1* Works exactly as it should, no problems with four players with four devices. In solo the bot seems to be unbeatable though. We have even teamed up to each find a clue someone else may have missed but we lose every time. ### 5/5 — Works perfectly *2022-02-03, version 2.3.0* No complaints. It’s a great board game and the app compliments it perfectly. ### 3/5 — Functional, but could be better in solo mode *2021-09-06, version 2.1.0* My only issue is that the app will often lose state if your device goes to sleep. In solo mode this is tricky, as the app provides the AI for the bot against which you play. It is possible to replay all of your moves, and the bot’s, when this happens — but it’s a pain. Would be much better if it implemented Apple’s app-specific ‘no auto lock’ feature. ### 5/5 — Great Game & App! *2021-07-05, version 2.0.0* We play hundreds of games a year, and this one is very polished and well put together. Highly suggested if you want a good time :). ONE COMMENT: we each were using our own phones for the app. We had a couple cases of “fat fingering”, and we would like a way to review the picks in the history tab. (Or at least review the choices history after the game is done, which it doesn’t let you do in the history tab) ### 5/5 — Excellent *2021-06-30, version 2.0.0* Very well-done. Simple and perfect. I'm not the biggest fan of apps in my boardgames, but this one does everything right. ### 5/5 — Works perfectly *2021-06-05, version 2.0.0* Well designed ### 5/5 — Easy to Use *2020-10-31, version 1.9.3* This app is the tool you need to play the board game “The Search For Planet X.” It is easy to use, and makes the game shine! ## Frequently asked questions about The Search for Planet X ### What is The Search for Planet X?
