Polar is the 30th and final Advanced floor in Monkey Ball and Super Monkey Ball, as well as the 59th Advanced stage in Super Monkey Ball Deluxe. It also appears as the 99th Ultimate stage with continues, and the 119th without. It is given a 6 out of 10 difficulty rating.
The stage has a stationary, circular platform in the center with concentric layers of moving platforms orbiting around it. Each layer has platforms varying in width, speed and direction (clockwise or counterclockwise). The goal occupies a platform on the outermost layer of platforms. One layer's platforms has bumpers in the center.
With good timing, the player can find a window of time in which the player can dash across the platforms and get in the goal.
