Keep Your Line is the 10th and final stage of the 8th world, Mystic Dome, and the final stage altogether in Super Monkey Ball 3D.
Description[]
This stage features a long pathway with slopes, turns, and curves. The pathway has orange guard rails at times. There are bananas along the way. There is also a bumper towards the end of the pathway.
Goal Tutorial[]
To get to the goal, roll along the first curve with a moderate amount of speed, and then roll along the next curve with a moderate amount of speed. Then, roll along the first path with sloped edges while rolling along the center as much as you can or against the orange guard rails, and then roll along the next path with sloped edges while rolling along the center as much as you can or against the orange guard rails. Then, roll up the next, small slope to the right while slowing down your speed as soon as you can so that you won't hit the upcoming bumper. Then, roll along the last two curves with a moderate amount of speed, and then roll into the goal.
