5 stars: This game is amazing it has some ads but not too much in my opinion. If you are not patient I do not recommend because when you first start you get money slow, but when you work your way up you get money wayyyyy faster.
3 stars: Leveling for the first two cities is fine, however after that getting to the third city took days to try and level up to level 40. Then when I finally got there, I maxed the city within 2 hours and now I need another 20 levels for the next city but 2 days after maxing city 3, I still haven't leveled up. It's a fun concept but the leveling system is ridiculously slow after about level 30. Loads of ads, but it's bearable.
3 stars: Fun game and good concept, but it feels like you have to watch ads to progress. Also a bug I had with the game is when you turn off vibration and reopen the app, the app says vibration is turned off, but its on.
3 stars: Good game, for that l'll give'em credit, but the ads are just NON-STOP. it really DRIVES me crazy. But i do like the game, upgrading lines, stations, how many subways ther are, its realy neat.and when the golden busses show up or you level up, when you click no video mutiplyer, it still makes you watch an ad.its STUPID
4 stars: It's really run and cool! You get to upgrade and stuff and go to different city's but I took one star off is because there's to many ads please fix. The bugs. But other then that this game is real fun!
3 stars: Takes a while to understand the mechanics behin...
