I mean I like belote but sometimes it's a little complicated to explain and there's a lot to track (and literally nobody plays it in the USA), so it's nice to have something that's a little lighter but keeps a lot of the features that make the game interesting, and I think twenty-nine keeps that balance. Not needing pen and paper or learning an ordering of suits is a big plus.
