World 1-A (New Super Mario Bros. 2)

A payment of five Star Coins is required to unlock this level.

This level takes place in a maze of pipes, making it similar to Pipe Maze from Super Mario Bros. 3. It contains one-way flippers from New Super Mario Bros., pipes that shoot Mario in the air, and a few Gold Rings to grab a lot of coins from golden enemies. At the end of the stage is the Flag Pole, which is set past four Piranha Plant-infested pipes that can be used to grab the tip of the pole.

Completing this level allows Mario to unlock a red Toad House and access World 1-Castle, skipping World 1-5.

Star Coins

 * Star Coin 1: The first one-way flipper (located on the floor) is blocked by breakable Brick Blocks. Going down the path will lead Mario to a small room with a red Koopa Troopa and the Star Coin.
 * Star Coin 2: The second Star Coin is located after the area with the checkpoint (right after a Coin Roulette Block). The one way flippers will block Mario's path to the Star Coin. He needs to move away from the flipper, being careful not to move out of the next flipper, until it returns to it's position. Mario can now obtain the Star Coin.
 * Star Coin 3: Between the pipe with four Piranha Plants and the last pipe that forms stairs near the end of the flagpole there will be a Hidden Block on the left side. Mario must go in the pipe that is now accessible. It will lead to a room where there is a Super Piranha Plant and a Koopa Troopa. The player can use the Koopa's shell to defeat the Super Piranha Plant, and make it safer to get to the last Star Coin.
