This is an introduction to people who are new to driving games. Here are the special pointers for people who never played this game before.

• When you are in the air, try to balance your flight by tilting forward or back.
• Even though it's like a normal race, the main goal is the stars. So try to perform as many tricks as you can within each lap and if you get first, the bonus stars should help unlock tracks if you can reach Grade S, which is the highest in the game.
• The special part of this game is the turbo. Unlike other racing games which the turbo has a limit, you have an unlimited amount of turbo but be mindful the temperature gauge detects how hot your engine is.
• When the turbo overheats, it will take time to cool down before you can use it again. However if you encounter an item or hit shallow water (not deep water), your engine stays cool giving you more time to use the turbo.
• If you see arrows or very blue water, that means it's out of bounds. If you hit the exclamation point, the terrain changes and if you crash, you have to hit the many times to get a major boost when you get back on track.
• Each truck has its own characteristics. Try out any trucks on the track and find which one fits your style. Also if you are lucky, there's two ways of unlocking new trucks or alternative truck colour. If you use the same truck ten times, you'll unlock another truck. For different colour, your truck needs to hit three Grade S to unlock a different colour style to the truck.
