Waluigi Casino is the third track of the Flower Cup in Mario Kart 9.
The track starts out on a large craps table. The players must race from the start to the end of the table while avoiding large sets of dice. At the end is a boost ramp, which leads out to several floating cards. There are two paths of cards to take, but both lead to a spinning roulette table with a large metallic ball as an obstacle. When the roulette table ends, there is a glider ramp on the end that the player must take. There are three slot machines on the way, and they can glide to either the tops of the machines or the mouths. The mouths are a harder glide, and therefore lead to a series of boosties. The series of slot machines leads out to the craps table where the race began.
