To get a goal 50 yards +, Snatch the ball from the opponent, try to corner your goal as much as you can from how far you can. In the first try, I recommend that it should be not before the half line. Thank Me Later :)
Hard.....no. It is hard when you are looking for the impo badge in the first go. What I do is, I get a set of coins in 1 go and save the game. Then the next set in the other go. So that I dont lose all my coins in just a miss-pressing of a key.
