Casino Paradise Zone (カジノパラダイスゾーン,Kajinoparadaisuzōn?) is the third Zone in Sonic Advance.
A vast neon base of flippers, balloons and garish bouncy blocks, the level sees whimsical castles and exploding fireworks throughout the background. Elastic flags help you to build up speed, and a wobbling platform reminiscent of Carnival Night Zone's "Barrel of Doom" crops up in Act 2. At the end of Act 2, Dr. Eggman must be fought in a round blue Egg Mobile along with a spiked sphere. They will both float in and out of 8 holes on the screen. The player must try to hit Doctor Eggman and avoid the spiked sphere.
The zone has bowl-shaped spinning drums which later appear in Angel Island Zone under different graphics.
The level starts off with a welcome sign, perhaps a reference to early screenshots of Sonic 1, which had a welcome sign at the beginning of Green Hill Zone.
The background is similar to the background at Walt Disney World Resort's Magic Kingdom.
Even though it's called "Casino Paradise", the zone itself has very little in common with other casino zones in the series, and more in common with the amusement park zones such as Twinkle Park from Sonic Adventure.
