It’s a bit niche, but I like Japanese mahjong (not the tile matching thing, the actual game) and have gotten hours out of an app called Kemono Mahjong. Cheap, onetime purchase w/no micro transactions and you can play against adjustable AI offline or online with others. It has plenty of guidance for new players.
If they’re not making a profit as it is charging rich rubberneckers 250K a trip and cutting corners on their builds, I can’t imagine they’ll ever be able to do it.
