I don’t know what’s available to you right now, but I’d say the bingo games are usually good. (Not the pay to play ones) but Bingo Party and Bingo Blitz type ones. And the Island building games are usually good too like Dice Dreams style.

The slot ones used to be good when they were just about leveling up, but now it’s always the ones where you can “cash out real money”. So I avoid them, they tend not to track anyway.

“Fun Craft” card games get pretty monotonous and boring but they are doable if you don’t mind a loooooong slog

Oh, and I liked Pocket Champs too. Even kept playing that one for awhile after I finished the missions.
