Subway Surfers is an arcade game that challenges your reactions. You're running nonstop on a railway track while there's a policeman trying to catch you. You must keep going no matter what but it isn't that easy. There are some obstacles and trains coming towards you and you need to react them quickly. You don't need to run all the time, though. You can grab your hoverboard when you're bored with running. Leap over and slide under any obstacle you run into. Don't forget to collect some coins and avoid getting hit. Have fun!
