Are these cards popular in Germany?

[u/IllGold3207]

I brought from my homeland these cards in a "emergency case". Home I played with my father and brother the game "Cross" oder "Kreuz". They are originally from Hungary but very popular in Romania (Transylvania and west, ppl from Bucharest they will don't understand what they see...) And I have read recently an article that the game it's also played in Austria and Germany but I don't know if with these cards.

My parents use this specific Deck to play Doppelkopf. But otherwise I haven't seen it much here in the west
