This is one of the game which is still in my mobile I have played lots of games but this is one of the game which I am still like play whenever I found free time. Its mind exercise game I will suggest to play with game but not for the long time just 1 or 2 hour on a day. The game is designed very good when you star the game its running slow slow and when you running success in game the speed will be increased. ones you connect this game with Facebook you can see the score of your friends who are using this game.
I am still played this game its very interesting game you need to completely focus on it when you played this game because ones your eyes will disconnect from game you will out of game. So many people spend lot of time in this game every day I will suggest when you have free time play it but not more then 1or 2 hour in a day.
