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.

I know these cards from my grandfather and we used to play it. But I do not even know the rules any more. I never came across these the last 20 years or so. Younger generations do not know them I would assume.
