Casino Night Zone
From Sonic Retro
Casino Night Zone, Act 1
The fourth zone in Sonic 2, Casino Night Zone fills the Casino Cliche requirement for the second Sonic game. A city that never sleeps, CNZ is full of pinball rooms, flashing lights, and slot machines. The player must beware of the slot machines because getting 3 Dr. Robotniks releases all of the player's rings.
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.
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!
