Layout
This episode takes place in Hotel Delfino's casino. Talking to the bellhop on the first floor of the hotel will allow Mario into the casino. In order to find the entrance to the secret course, Mario has to spray the two large slot machines until they both line up on triple 7s. The slots with a slanted square around it will move individually upon being sprayed, while the slots in the circle will all move at once. The slot machines can also land on Coins or Boos. When both slot machines land on triple 7s, the red curtain in the back of the room will rise, revealing a panel of question marks. The player has to spray each panel to flip them over, eventually creating an image of a Shine Sprite. Once the image is formed, the panels will raise and a Warp Pipe will be revealed. Entering the Warp Pipe will take Mario to the secret course, and Shadow Mario will take F.L.U.D.D. away upon entering.

The secret course is made up of many moving blocks. On the first platform, there are two cubes moving across that will push Mario off the edge if the player isn't careful. To get to the second platform, Mario has to use a floating cube to cross the chasm, then avoid getting pushed by or squished between the moving cubes as he makes his way across the second platform. The next moving cube will take Mario to a series of long moving blocks he has to jump between. Afterward is a rolling block like those found in The Secret of Ricco Tower. After crossing that, Mario has to ride a large, rotating cube as it moves across the chasm, which leads to the platform with the Shine Sprite.

Red Coin Winnings in the Casino
Re-entering this course will allow Mario to use F.L.U.D.D. and do a Red Coin challenge. Ground Pounding the Red Coin Switch will cause eight Red Coins to appear throughout the level and the player has to collect them within a time limit of one minute. Collecting them all will cause the Shine Sprite to appear at the end of the level, but failure to collect the Red Coins within the time limit will result in Mario losing a life. The locations of the Red Coins are:
 * The first Red Coin is in the center of the first platform.
 * The second Red Coin is on the path of the first cube crossing the chasm.
 * The third Red Coin is in the center of the second platform.
 * The fourth Red Coin is on the path of the second cube crossing the chasm.
 * The next three Red Coins are placed over the horizontally moving platforms.
 * The eight Red Coin is placed over the rotating log platform.
