In Subway Surfers, you can compare scores with your friends and help them earn extra coins without any extra effort.

Clicking the Social button on the main menu takes you to your Game Center or Facebook friends list. You can see their best scores here so you know what you're up against when you play.

A cool way to earn extra gold is to let your friends run so you can earn extra money. For every 50 friends run, you'll get a coin bag with valuable coins inside.
