Opponent
Do not be too concerned about beating the A.I. opponent the game puts you up against, it is more important to focus on pacing yourself and completing the track without running out of Fuel or dying. You can always go back to improve your time or beat your opponent.
Tricky Sections
Keep an eye on the opponent you are playing against if they finish the whole track so you can see how tricky sections are completed.
Accelerator
Just keeping the accelerator pressed down will not get you far, to successfully navigate the various tracks will require subtle touches. This is especially true when you are airborne and need to correct your tilt.
Loop De Loop
You do not need to use your Fuel at all when you head into a loop de loop as the game puts speed strips at the start of the loop that provide enough momentum to get you through to the other side.
Bonus Points
Learn the layout of a course first by completing it before replaying it again to earn bonus points from doing jumps and stunts.
Free Gifts and Gems
Check back to the game regularly to get the free gifts and gems that become available every few hours. You can also take advantage of the video advertisements to double the amount of gems you get.
Stunt Chests
The quickest way to unlock the stunt chests and the huge rewards that can be found inside them is by doing flips and getting big air.
Go Back
Consider going back to previous tracks to get the best times and the rewards that come with them when you have unlocked some new tracks and your car is more powerful.
Game Over
The game is not necessarily over when you run out of Fuel, if you can roll towards a fuel cannister and grab it you will get powered up and be able to continue.
Landing
Avoid landing upside down as doing so will blow your car up. Even if you manage to correct your bounce after landing upside down you will still blow your car up.
