Trials-like Rock(s) Rider HD is free for the first time on the App Store

If you've been disappointed by the free to play mechanisms of the real Trials Frontier on mobile, you might be looking for a worthy replacement.

Rock(s) Rider is at least looking gorgeous in its HD version, using a engine that will exploit your device's horsepower.

You know what to expect from the gameplay though, as you'll need to defy gravity and maintain control of your bike through levels filled with hazards and traps.
