Most of these stages may contain elements of the Urban theme. The two main versions of the amusement theme are Casino themed stages or Park themed stages. The theme is highly varied and levels may include balloons, theme park rides, pinball-style flippers or casino-style gambling games. Stages with an amusement theme typically have bright lights, bouncy obstacles (mostly springs and bumpers), and colorful backgrounds. To hit him, Sonic should spin dash up the sides of the arena and jump off onto Robotnik's machine when he approaches, keeping control of himself at all times.A slot machine, a staple of the amusement theme, from Sonic the Hedgehog 2. Robotnik traps Sonic within a giant pinball arena and tries to kill him with his neon spike-ball machine. Note that in this case, Jackpots only act as doublers in the case of only Jackpots and Bars, i.e., two Bars with one Jackpot is worth 40 rings, and one Bar with two Jackpots is worth 80 rings, but one Bar and one Jackpot is only worth 2 rings. A Bar will also give out rings depending on how many there are.

One Jackpot and two icons give out the standard prize, but two Jackpots will double the standard prize for the third icon.

In addition, a Jackpot or two can also act as a wild card or wild cards, rewarding rings even though the other reel(s) are not Jackpots. To win big at the slots hold down the A button when the reels are spinning and nine times out of ten you'll get 3 matching symbols.

3 Robotniks: -100 rings (if you have less then 100 rings then you will lose all the rings you do have, but you don't die).

3 Jackpots: 150 rings (and an extra life for getting 100 rings).

The possibilities are: Sonic, Tails, Ring, Bar, Jackpot or Robotnik. The slot machines give out different prizes depending on when the reels land. A straightforward zone with many objects to fool around with (such as pinball flippers and bumpers), and no real threats apart from some crushing blue blocks and a slow badnik called Crawl. This zone became the first of many casino/carnival style zones that would eventually be included in future Sonic titles. A city that never sleeps, full of pinball rooms, flashing lights, and slot machines.
