[SOLVED] Looking for the name of a specific board game, recommended on tildes

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?
