According to this guide, there are only 5.
Bottle #1
As soon as you have your Sword and Shield in hand, head on over to the Bazaar in the middle of Skyloft and speak with Luv, the owner of the Potion Shop, and she will inform you about her potions. After noticing that you don’t have one, she will provide you with an Empty Bottle that she was storing.
Bottle #2
When you enter the temple at the Sealed Grounds for the first time, before speaking with the old woman at the top of the stairs, look over to the right of the stairs. Here you will find a small brown chest, and inside will be your second Bottle, prefilled with Revitalizing Potion.
Bottle #3
Bottle #3 can be obtained by completing the Missing Sister side quest, which becomes available after completing the Lost Child side quest. (The Lost Child quest should be completed ASAP as it unlocks the ability to perform additional side quests that yield great rewards that will be extremely helpful throughout the rest of the game.
Bottle #4
Once you obtain the Mogma Mitts in the Fire Sanctuary, Head back to the first floor. Locate the circular room in which you can now dig underground. Take Link underground and hit the switch to open the gate above you; this will open a new path filled with water plants. Use the switch nearby in order to open more gates and poke one of the water plants to skewer it with your sword. Head through the gate and make a right. Kill the Magmanos (slash to toss the water plant at it, then slash the Magmanos itself); this will lower the lava level giving you access to a new path which ends with a chest containing your fourth Empty Bottle.
Bottle #5
This bottle is located inside a Goddess Cube Chest that becomes available after striking a Goddess Cube in the Eldin Volcano. This cube cannot be reached or seen until the second trip to this location.
The majority of this game can be pretty easy. Falling through the Fortune Rings and dodging the Dodoh Balls can be easily navigated once you know which paths are relatively safe and which ones should be avoided. It's the landing that is the tough part. I'll walk through these phases separately. But first...
Control:
When free falling, the controller is pretty sensitive to your movements. For this game, you barely need to tilt it to move in the direction you want, and you'll have plenty of time to move to the part of the screen you want without it getting out of control. You shouldn't try to tilt more than 10 degrees, you shouldn't need to.
The fall:
First let's understand what you're up against. There are 5 Fortune Rings and 4 sets of Dodoh Balls alternating starting with the rings. We want to avoid the Dodoh Balls so here's how big each set is and how they move.
- 4 Dodoh Balls in a small square, rotating.
- 1 Dodoh Ball in the center, stationary.
- 4 Dodoh Balls in a larger square, rotating.
- 3 Dodoh Balls in a triangle, stationary.
Avoiding the stationary balls should be simple so I'll leave that to you. However you have to be careful with the rotating ones. My advice, never try to weave through the rotating balls (sets 1 and 3), always go through the middle. You can risk it and try, but why make it harder on yourself?
The landing:
Ok this is where it gets tricky. I have to admit though, this is not foolproof advice. There is a degree of randomness in this game so it won't always be the same. But, this should be very close every time. The risk of playing this game is very small but the reward is so much bigger. I can almost guarantee you will miss a lot here landing in the Loser Space, but I promise you'll win enough here too.
At this point, I will assume you have a 10x multiplier by getting all 5 rings. Dodoh claims that the wheel slows down for every ring you get. I don't know if that's really true or not, I can't tell the difference. So I am assuming that the wheel should be rotating at roughly the same rate here.
First thing to note is the ground and how it looks like. You should notice that there is a orange and yellow "star" each with 12 points. I would look at these like they are clocks. You'll need to use these as reference points to help you with this. These "clocks" are mostly stationary. You just need to be aware that the camera is actually rotating a little too.
As far as I can tell, if you fall in the open stance (and not diving headfirst), the wheel will generally make almost a full rotation from when you hit the last Fortune Ring and you hit the ground; sometimes a little less, sometimes a little more, or it could just be my reaction time not being consistent. I estimate 11/12 of a rotation based on the video I took.
Before you reach the last ring, find the 50 rupee space and keep tabs on it's location relative to the clocks. You'll also want to pay attention to where Link is relative to the ring so you can get ready.
When you finally reach the ring and you hear the sound of collecting it, find the point of the orange or yellow star that is closest to the middle of the space and keep track of that. The region that between that point and the previous point of the same color is your target area to land in.
Also, remember that it will probably be rotating too. At that point, it's just a matter of hitting your target and making any adjustments you can. With any luck, the 50 rupee space should come up right under you. If you know you're behind, you could dive in headfirst (point the WiiMote straight down) and hope that will make up for it.
Here's a video I recorded that you can analyze:
Best Answer
You can go to the pause menu and click the down button in the D-pad, and it will center the Wii remote. (If that's what you wanted.)
