The first expansion gets you up to 20 I think, then the next one gets you to 25 then the next one to 30, and the next one which is soon coming out will get you to 30. Also I've spent near $20 on this game, and still think it was totally worth it, it was a much better purchase than some of the ten dollar games I've gotten, I'm glad that I payed all the money I did, because it allows the devs to keep making the game better, and making even better future games.
