Surf Riders is a funny skill game in which you have to adjust the height of the waves in order to keep your surfer on his feet. Raise the waves to make sure your surfer doesn't crash into the oncoming wall of water. You'll have to lower your wave if the next wave isn't so tall, because otherwise your surfer will slip off his board and end up underwater. Collect the coins as you go. With 50 coins, you can unlock a range of funny surfers.
