Challenge yourself with Mad Skills BMX (pictures)

If you like a serious challenge, this racing game has all the bells and whistles, offering plenty of free content and several tracks to thrill and frustrate you.

This sequel to Mad Skills Motocross offers beautiful graphics as you fly to the finish line.

Before you start racing, you can select from five free bike designs and three you can pay for with an in-app purchase.

The game starts pretty easy, but as you complete each skill level track pack, you'll move on to the next for some serious challenges.

The first level of the game gives you tips on how to perform all the basic moves.

The drag-down-and-hold move is great for both speeding up on down slopes, and racing through rolling jumps or "Whoops."

Drag down to speed through the low rolling jumps. Editors note: I didn't quite pull it off here.

When you master the pull-down-and-hold move, you'll race down hills to build up speed.

The game helps you along showing you when you want to jump in the tutorial level.
