Popular examples: KOTOR (Pazaak), Witcher 3 (Gwent), Final Fantasy series (various card games)
Part of the reason Pazaak works well is that it is an adaptation of Blackjack, a well-known game from the real-world. What are other games you'd like to see simplified/themed/expanded on with progression mechanics as a diversion in an RPG?
I think Yahtzee is a high potential example. The die faces could be swapped out for thematic elements, players could collect dice with varied faces and distributions, the scoring rows could vary between taverns, special abilities could affect the rolls of yourself or your opponent, and so on.
Aside: I find it particularly strange that MMOs haven't done this. It would clearly extend play time and therefore subscriptions if Hearthstone or Pazaak were a part of WoW and SWOTOR.
