Translation:Let's all play cards.
What would be the Hawaiian for "Let's all play cards" then?
I believe this sentence can also mean that.
Is "pepa" acting as an adverb here?
My guess is that "pāʻani pepa" is a sort of compound verb, meaning "card-play," as in "Let's card-play."
I think so, because it doesn't need an article "ka" pepa.
