Technique

Technique (World 9-10) is the 90th level in Super Monkey Ball 651

Description
The stage of a large square platform between the bottom of four pillars, with another small platform in front of it (which is where the player starts) and an identical platform on the opposite side of the pillars at the top, where the goal rests. Three seconds after the player spawns, the large square platform will quickly flip onto it's right side, and then another three seconds later flip upside down, giving the effect that the platform is slowly climbing the tower. Then it'll repeat but this time on the left side. Then it'll repeat all of this one more time before finally reaching the top of the pillars, allowing the player to reach the goal.

Goal Tutorial
Position yourself between the second and third column of the checkers from the left on the large platform and face forward. Half a second after the platform starts flipping, pull back left and, using the back-right pillar as a visual guide, try to land on the side of the platform. If you do this successfully, you will bounce on the platform about three times. On the third bounce, pull towards the center of the pillars to stick to the underside of the platform. Now repeat the process again but facing the other direction (towards where the starting platform is). At this point, you should be about halfway up. Then repeat the whole thing one more time. Be careful, on the final transition to the side of the platform, you won't have the pillars as a visual cue as they only go as far as the goal platform. Instead, try to aim directly for the goal platform, using the mini map if necessary. The animation will not repeat, so if you miss the first cycle, you will have to retry. (See external link 1)

To save time, there is a shortcut. After making it to the halfway point, head towards the right side of the platform (with the goal platform being the front and the start platform being the back). At 46 flat, rush towards the left side and with enough speed, the flipping platform should fling you straight up to the goal platform. (See external link 2)
