I really like Stack the States and I literally play it everyday. I feel almost everything about Stack the States is great. The gameplay is fun and it is pretty good to help you learn more about the states. The learn functionality is helpful as without it, the games will be much harder. Earning states from playing the stack game is also good as it gives players a reason to keep playing. It’s nice to keep earning states as prizes and seeing the states cities, landmarks, and elevations. The only thing I don’t like about it is that it is a paid game. It’s only $2.99 and this game is pretty good for what it is however, there isn’t too much to do in the game. Despite being a nice little game for what it is, it really can only last so long, I think about a month or so. I guess it’s a good trade off as this game has no ads or in-app purchases. If you do want to get a game like this, I recommend Stack the Countries. I haven’t played it but I would think that with more countries, there is more content in that game.
