Need help with Redline? Most answers are below. If yours is not, get in touch and we will reply as soon as we can.
How do I play?
Tap anywhere to launch, then tap each time the needle reaches the yellow band. On a computer, Space or Enter also works.
How do I unlock cars and paint?
Finish runs to bank REP. Each new build stage unlocks garage options, which you choose from the Garage button.
