The Secret of Casino Delfino

"Ah, the Jumbo Slots... Well, triple 7s is obviously the best you can do. I've yet to see anyone get triple 7s on BOTH slots!"

- Pianta

The Secret of Casino Delfino is the fourth episode of Sirena Beach in Super Mario Sunshine. The episode's objective is to enter the casino to find and clear a secret course. After completing the episode once, the player can return to this episode to collect the Secret Shine Red Coin Winnings in the Casino.

This episode takes place in Hotel Delfino's casino. Talking to the bellhop on the first floor of the hotel allows 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 move individually upon being sprayed, while the slots in the circle all move at once. The slot machines can also land on coins or Boos, and the latter slot machine will spew out these items if the slots line up as three in a row. When both slot machines land on triple 7s, the red curtain in the back of the room rises, revealing a panel of question marks. Mario has to spray each panel to flip them over, eventually creating an image of a Shine Sprite. Once the image is formed, the panels raise and a Warp Pipe is revealed. Entering the Warp Pipe takes Mario to the secret course, and Shadow Mario takes FLUDD away upon attempting this level for the first time.

The secret course is made up of many moving blocks. On the first platform, there are two cubes moving across that can push Mario off the edge. 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 takes Mario to a series of long wooden blocks that move in and out of holes in the wall that 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.

A glitch exists that allows Mario to skip the slot machines and panel puzzle entirely, and skip straight to the green pipe that takes him to the secret level.
