Super Monkey Ball 2 - Advanced Extra

The Advanced difficulty continues with Advanced Extra. By finishing the 30 Advanced stages without a continue (not an easy feat, as this set contains some real devils in there--namely Reversible Gear, Twister, Launchers and Arthropod, the four of which can clear out your 99 lives by themselves), you get a set of 10 more stages! Unlike with Beginner Extra, these are all original and can only be found here:
EX 1 Auto Doors
EX 2 Heavy Sphere
EX 3 Stagger
EX 4 U.F.O.
EX 5 Ring Bridges
EX 6 Domes
EX 7 Amida Lot
EX 8 Long Slider
EX 9 Grid Bridge
EX 10 Teapot
Yes, "Teapot." The difficulty of these stages are easily around the tail end of the Story Mode. Extra stages are always at least a notch above the regular stages in how tough they are. After all, you're supposed to finish the regular stages without a continue, but you're free to use the continues as you wish in these. And if you're encountering them for the first time, you may well need them all.
Note that there is a big reflective drawing of Gongon on the titular Heavy Sphere. Go ahead, take a look.
In U.F.O., I'm not sure if you can deduce what's happening, but the saucer flips over. The challenge here is to not fall through that tiny hole. It's not terribly difficult as long as you retreat to a wall.
I had a phone call when playing Ring Bridges. I apologize for that. I've edited out the middle part of the pause.
Now, you may be wondering what an amida lot is. Short for "amidakuji," or "ghost leg," it started as a type of lottery, but it became predictable and had since become a schoolyard game or a type of puzzle. You draw a series of vertical lines of equal length spaced equally far apart. Then, you draw a bunch of horizontal lines extending from one vertical line to an adjacent one (but no further). A prize is described at the bottom of each vertical line. To play, someone else takes a pencil and chooses one of the vertical lines. He or she draws from the top of the line. Each time the pencil reaches a horizontal line, he or she must follow that to another vertical line, where he or she continues going downwards. When the player reaches the bottom of a vertical line, he or she wins the prize described there.
It's best seen as a demonstration. This stage's ground is designed as an amida lot: You can see the seven vertical lines (though they can have any amount greater than 2) and the horizontal lines connecting them. The bumpers are tracing paths a player would take, following a vertical line downwards, then turning when they reach a horizontal line and continuing downwards after. Still confused? I'd recommend a Google search. Look for "amidakuji," of course.
Amida lots show up frequently in video games of Japanese origin. Perhaps the best-known example is a WarioWare microgame, which first appeared in the original and has since shown up in D.I.Y. as one of Orbulon's games. The Pipe Maze lottery in Mario Party is another much-seen example.
Long Slider may well be the biggest stage in this game, using the full height limit and a lot of the length and depth limit too. This would've been awesome on the 3DS.
Sorry for editing out getting to the goal for Grid Bridge. But rest assured, I did exactly what I did in the first attempt, except go one unit more to the right.
