A very cool trick for building tracks is the usage of pipes you can drive upon. They provide a great challenge as you can save valueable seconds when driving upon them, but the risk of falling down is high and if you do, you'll restart inside the pipe. There are 2 ways to implement it:

1. This one is for free: you place a pipe with its roof height the same as the tile before it (see screen 1). The pipe will automatically be accessed by driving towards it. And then the fun begins! Try to throw in a pipe turn or a raised up pipe in order to make it more difficult to stay upon it. The pipe roof has no borders so it's hard to stay there.

Make sure to place the next module after the pipe section as usual (see screen 2), otherwise ReVolt won't export your track.

2. This one is more of a challenge: place a jump 1 or 2 tiles before the normal pipe entrance and build a normal pipe with entrance behind it (see screen 1). You'll need enough speed to access this one (experiment with the height of the jump) but the reward is even greater!

You can place tiles around the pipe (see screen 2) to produce borders to crush into. I recommend this because it wouldn't be much of a reward for a cool jump if you instantly land beside the pipe and restart in it...
