Subway surfer is a very interesting game. In this game you have go on and on without getting caught from police.
I have a hacked game of this subway surfer that means I have infinity coin, skates, rocket, key etc. But playing its hacked version its not so interesting.
In my past when I used to play this game when I restore all of my coin, key and skates lost. Then I found hacked of this game. In this game you required lots of concentration I think this game increase lots of concentration to gain. Your focus increase too. So I recommend you to play this games
