World 1-1 (New Super Mario Bros. Wii)

World 1-1 is the first level of World 1, and subsequently, of New Super Mario Bros. Wii.

Layout
In the beginning of the stage, just like in New Super Mario Bros., Princess Peach's Castle can be seen in the background. When the players start, there are three ? Blocks, a few Brick Blocks, and a Goomba. To the right are some moving sections of land, the latter of which has three platforms above it, and a green Pipe within it that leads to a room with coins, Brick Blocks, and a P-Switch. Ahead is the Midway Flag.

If players have the Propeller Suit, they can access the game's first Red Ring. Further along is a rolling hill with a secret alcove; if the player jumps onto the green Pipe and waits, they will be brought to an area with three hidden 1-Up Mushrooms and dozens of coins. The pipe itself leads to an area with a Star Coin. After jumping over a few pits, the Flagpole can be seen past the final rolling hill.

Star Coins

 * Star Coin 1: After the midway flag, over three ? Blocks. The player should use a Propeller Suit or a running jump to reach it.
 * Star Coin 2: At the end of the platform with the Red Coins, the player should spin to the next platform and then skip the following platform with the Red Koopa and collect another Star Coin.
 * Star Coin 3: The player should look for a rolling hill with a green Pipe. After entering the pipe, they should Wall Jump or use a Propeller Suit to collect the last Star Coin.
