Hit your thrust just before the announcer says "Go" for a faster start to get a starting boost.

Enter the U.K. area that has a hill right before a wall that locks you from the area where Japan is located. In order to do this trick, you must hit the hill fast, jump from it, then do a spin. Do it correctly to end up jumping over the wall and into the Japan area before it is normally available.

There is a globe pretty close to the start of the Japan 1 race. Once you go through the figure eight track at the start, there is a section that goes up a wall and down the other side. If you keep to the right and do not go up the wall, you can see a loop-the-loop. Go straight and do not try turning while in the loop to avoid falling. The globe is right at the top. Be careful, as other trickers can take your globe by touching you.

This shortcut is located where a section of the railing is out. Go straight through it and land straight. This shortcut may show the message "Wrong Way", but you have taken a jump from the broken rail.

You will see a large clock In UK races 1 and 2. Towards the end of the course in race 1, go up the ramp and use a boogie drill or hammer drill to break the glass and save some time. At the start of race 2, go on the right side and get the speed boost. Once done, break the glass by using boogie drill or hammer drill to cut off a sharp turn.

Just stay there when the starting countdown ends, then jump and do a 360 in the air. Repeat this while making sure you do the move while in the air. You will receive 500 points each time. Repeat this until reaching 1500 points. You can also take your time to finish with about 30 seconds.

Ride around the track and, when you see the corner that has a broken rail, ride through the open shortcut. You will no longer have to go around the corner again.
