To get this achievement you need to beat a friend's skill game score. To do this you must have a friend who has fifa 15 and has a score for any of the skill games. Then go to play, skill games, and pick a skill game which your friend has played and try to beat his score. You must have a lower score than your friend and your job is to get a score higher than his. The achievement will pop once the skill game has been completed and you have overtaken his place in the leaderboards.
Thanks for reading my guide and I hope it helps you get this achievement.
