Description provided by Foxtrot Games on YouTube:
Coming to Kickstarter in October! Foxtrot Games does their first live playthrough of the prototype, The Search for Planet X.
The Search for Planet X is an app-driven, logic puzzle, deduction game. Players take on the role of astronomers, competing to be the first to locate Planet X. Each game, the companion app will randomly select locations for the objects in the sky following a set of pre-defined logic rules.
On your turn, you'll interact with the app to conduct various research. You might scan the visible night sky for asteroid fields in sector 2-6, and the app may tell you that there is 1. Since they are always in pairs, you know there's no asteroid field in sectors 3, 4, or 5; if there were, it's pair would have shown up on the scan also. That means there's a pair of asteroid fields in 1-2 or in 5-6. The consistent logic rules are displayed on the back of your player screen, for easy reference.
You might also attend a conference where you'll learn a logic rule that applies only in your particular game, something like "No gas cloud is within 2 sectors of a comet." You'll have a custom deduction sheet where you can circle or cross out things as you discover them or rule them out.
As the game progresses, the earth will orbit the sun on the board, which will change which sectors of the sky are visible for that turn. Once you start to learn where certain objects are located in the sky, you'll be able to submit theories. If you believe there's a gas cloud here in 11, you can place a gas cloud token there. This token will undergo peer review and slide towards the center over the next few rounds. Eventually it will be revealed, and the app will perform the peer review and tell everyone whether or not there is indeed a gas cloud in 11. If there is, you'll score the points for it, no one else will be able to publish there; if there's not, then you'll all be able to rule that out.
Eventually, you'll figure out where enough objects are and enough of the logic rules that apply in your game that you'll be able to deduce where Planet X must be.
