New Super Mario Bros. 2: Rainbows

I never found any of the Rainbow courses, so I set out to look for them. There's a fairly specific method to follow them: in any course with a flagpole, land on the flagpole when the last two digits match the world number. For each of them, I recommend bringing a Super Leaf.

1-Rainbow
Make sure your time ends in "11" when you reach the flagpole. This will make the original flagpole music from Super Mario Bros. play and you'll get fireworks, in a number equal to the world number. The level will appear where the world's start arrow is. Take the pipe cannon up and you'll enter a world of rainbows with remixed Coin Heaven music. In this one, you'll stand on a moving platform as coins rain down. The random coin blocks have better odds here. Between the first and second sets of random coin blocks, a 100-Coin coin will appear. Try to get it. There is also a random coin block that can give you a 100-Coin coin. The platform will eventually move past a wall, so you'll drop back down to the World Map. You can drop down at any time without penalty.

2-Rainbow
Your time must end in "22" to access this level. The cannon will take you to an automatically scrolling level on rainbow platforms. The coins will rain down in lines. The 100-Coin coin will appear near the higher platforms. Be sure to get the Red Coins: getting them will put a Gold Flower as your reserve item.

3-Rainbow
Your time must end in "33" to access this level. The cannon will take you to a moving platform. The coins appear from below. Some 10-Coin coins will go by quickly, then the 100-Coin coin. There are quite a few random coin blocks. Eventually, the platform will reach a wall.

4-Rainbow
 Your time must end in "44" to access this level. The cannon will take you to an automatically scrolling rainbow level. The coins will rain down and arc from the pipes. The 100-Coin coin will appear up the platform "stairs". There are Red Coins here that appear in the circling coins.

5-Rainbow
Your time must end in "55" to access this level. The cannon will take you to a moving platform. The coins will arc from below. The 100-Coin coin will appear after the first random coin block. One random coin block can give you a 100-Coin coin.

6-Rainbow
Your time must end in "66" to access this level. The cannon will take you to an automatically scrolling ranbow level. There are coins spinning in rings over bouncy pink mushrooms. The 100-Coin coin will appear over the high platform between two rings. There are Red Coins here that will appear in the centers of the rings.

Mushroom-Rainbow
Your time must end in "77" to access this level. Mushroom isn't a number, so this is what you need. The cannon will take you to a moving platform. The coins will appear from above and below, and in spinning rings. There is a random coin block that can give you a 100-Coin coin. There are also Red Coins that appear on the outer rings of coins. The 100-Coin coin appears at the end. You'll have to jump for it.

Flower-Rainbow
Your time must end in "88" to access this level. The cannon will take you to an automatically scrolling rainbow level. The coins will spin more slowly in bands that look like a ferris wheel. There are Red Coins that appear via parachute. The 100-Coin coin appears here.

Star-Rainbow
Your time must end in "99" to access this level. The cannon will take you to a moving platform. The coins will appear in star formations from above. 10-Coin coins will rain down, as well as the 100-Coin coin. You can get another from the random coin block. Red Coins appear via parachute.

Coin Total: 75,654
Well, that's it. We're totally done here. My coin total wasn't too bad, but it's nowhere near the 1 million coin goal. I'll reach it slowly but surely.
