Q: Is there a Rick & Morty Fluxx?

A: Yes, but only in Polish. Our relationship with Cartoon Network ended without us getting to make this ourselves, although Andy really wanted to, as he’s a big fan of the show. The good news is that the Polish publisher who licenses Fluxx from us also has the rights to make games with the Rick & Morty assets, so they have. As with Star Wars Fluxx, Andy did insist on doing the design work himself.

The Polish publisher is Black Monk games. We do not know whether they have kept the game in print, but you can try contacting them:

or, if you don’t speak Polish, here is their page as punched in to Google translate:
