The fourth zone in Sonic 2, Casino Night Zone fills the Casino cliché requirement for the second Sonic game. A city that never sleeps, Casino Night Zone is full of pinball rooms, flashing lights, and slot machines. The player must beware of the slot machines, because getting three Dr. Robotniks releases 100 of the player's rings. On the other hand, if the player is lucky enough, he can get up to 999 rings (see picture on the right).

Casino Night Zone had one of the most drastic art changes between the Sonic 2 Beta and the final, changing from a pink card-suit-based scheme to a golden area.

The Casino Night Zone makes appearances in two episodes of Adventures of Sonic the Hedgehog: "High Stakes Sonic" and "Mobius 5000". It also makes an appearance in issue #1 of the Sonic the Hedgehog comic.

The zone in Sonic the Hedgehog 4, Casino Street Zone, shares traits with this zone (including the badnik "Crawl"), but was not inspired by Casino Night Zone, as stated by Ken Balough.

This stage marks its return as a bonus DLC pinball mini-game stage for those who preorder Sonic Generations for Xbox 360 and Sony PlayStation 3, and as a full complete stage in the 3DS version.

Instruction Manual Description

Sparkling neon lights and glittering gold fill the Casino with razzmatazz! Play the machines with Button A, B or C. Flip the levers and push down the springs to send Sonic reeling like a bouncing blue pinball!

Sonic Team Commentary (from Sonic Jam Strategy Guide)

The slot machines are based on our experience going to casinos while working in America. Riding in a car, it would take about four hours to get to Las Vegas. We would call those trips Entertainment Research (laughs). But the game does contain a lot of references to the things we experienced in America.

Enemies

  • Crawl - Crab enemy, protects itself with a shield, so it can only be destroyed from behind.
