For the Action game Faerie Cloud Racers, here's a couple of tips.

1) Setting the speed to high will get you more points, of course, but the speed can be a bit much for some. Set the detail to high and the screen size to full to get it to slow down some.

2) Guaranteed Win against the Computer: You start out heading right. Quickly tap down then right to go under your opponent. She will head past you, then head up when she reaches the point where you turned. Get as close to the wall as you can, then tap down then left. You'll now be heading back towards the left. Get as close to the left wall as you can, then tap down then right. The goal here is to cut of the entire bottom half of the screen from your opponent. When you have the bottom half to yourself, continue the pattern of alternating left and right, getting as close to the wall as you can each pass. The computer will 99.9% of the time be unable to match you, and you will win. 1000np in under 3 minutes of playtime, 3 times a day!
---note: if your opponent gets into the bottom half of the screen before you seal it off, try to get into the top half and seal that off instead!
