As the title suggests, I am lookimg for the name of an existing boardgame.
Some time ago (months), there was a discussion about boardgame recommendations. One person described a very interesting boardgame, which I wanted to gift my family for christmas, but I sadly closed the tab with it and I can't find the original post anymore.

The game goes as follows:
One player builds a construct with different shapes and colours according to certain guidelines. The other players now have to find the rules, which the presentated construct follows, by building their own construct and getting feedback from the gamemaster, if it fulfills their guidelines.

According to the poster, this game was originally a game a group of friends played in college, it became so popular that they created a sellable version. Recently they revamped it.

P.S. I am not really familiar with this kind of post, so if I did anything wrong, some feedback would be nice.

P.P.S. Is there some kind of function (maybe through tags?) to mark this post as solved, if hopefully someone managed to recognise the game?

I'm working on a card game that would arrive to your home without a rulebook, but I'm having a comprehensibility problem. Below is some basic rules text for this game. If you had enough time to decipher the below, do you believe you could understand its meaning? Are there any words which are too obscure?

Join a game by selecting a central objective from among its currently apparent contests. Catch a turn from wherever to start playing then describe your plan aloud to the group. If anyone agrees that your plan is valid (legal?) then they can accept you into the game as their second. Anyone else who wants to join at this point may also join/rejoin as your teammate.

Contests are tensions between two scales which can be described by consensus. For example, imagine I'm 1v1 with Ah while you are on a team with Bo and Ci against Du. Imagine Du sees that the tide is not in their favor, and decides to jump ship to the other game. They may do so at any time by admitting they want out of their losing position and describing which team in the other game they would like to swing over to join (My team or Ah's.). Bo, Ci, and you are left in the boat without an opponent. This may cause a crisis (see "Crisis Card").

Farewell, I am off to prepare lunch for a child.

Maybe it's a random itch.io find; maybe it's a minor title from a long forgotten console; maybe it's a dev project your friend asked you to play test. Whatever it is, you think it's neat, and you never see it mentioned anywhere.

Tell us about the game -- what is it? Why is it noteworthy? Do you think it deserves more recognition than it's gotten? Why do you think it's as hidden away as it is?
