Centrifugal is the 1st Master stage of Super Monkey Ball 2 and Super Monkey Ball Banana Mania, the 271st Ultimate stage without continues in Super Monkey Ball Deluxe, and the 121st Marathon stage of Super Monkey Ball 2 in Super Monkey Ball Banana Mania.
The stage resembles a massive, rotating bowl without a central base. The goal is located in the second section from the top. The bowl constantly rotates in a forceful manner, requiring the monkey to travel backwards in order to stay on course. There is a trail of bananas, lining up with the goal.
There is one goal in this stage, a Blue Goal. To get to it, You'll want to fall into the stage, and make your way up to the second layer from the top, and start going backwards. Zoom the map into its closest setting, and keep moving backwards. Use the bananas as a guide to stayed lined up with the goal. When the goal appears on your display, move into it. Make sure not to move into the top-most zone, or else you will be pushed off-course.
You can do the stage slightly faster by falling off the platform at 56:00 seconds, and then doing what you normally do with beating the stage. Note that you'll want to fall off at exactly the start of that time, or you'll go right past the goal. This will get you to the goal at about 45:00 seconds as opposed to getting it at around 37:00 seconds.
Instant Unlock Glitch
Just like Ruin, a stage in Super Monkey Ball, if timed properly, you can skip all the way to the end of Master by playing through this stage again. Wait until the time reaches nearly to zero seconds, and quickly get into the goal to when the announcer says "Time Over" and the goal tape breaks at the same time. Your monkey should be pouting and celebrating. If done correctly, the stage number should say "10" instead of "1", and you can easily go on to the next stages.
