All right, I managed to get the arena up at last. And here it is.

Casino Night Zone - version 1.5

Yep! This Sonic-inspired stage has it all! A hammer corner, a bumper corner, and 2 Corner Patrol Zones. Drive over the middle slot in the slot machine to activate it (every 30 seconds), and if you get three in a row, the automatic hazards dish out MORE PAIN! Also some paddles and springs on opposite walls will send you for a loop!
