The third level in Sonic 3D: Flickies' Island, Spring Stadium Zone fulfills the casino trope in the sense that the whole level is one big pinball machine, much like Sonic 2's Casino Night Zone. The boss of this level has Robotnik attacking you with diabolical hands attached to his new machine.
Although the pinball flippers are absent, the feel of the Pinball Machine can be felt by steep hills, side bumpers, and round bumpers. Springs embedded in the floor can spring up and let you collect a few rings, however not every red spring on the floor will spring you up.
Some obstacles not only include the pinball bumpers and springs but also balloons which can bring you up onto the next platform, much like those in Carnival Night Zone and the two-player stage Balloon Park, both from Sonic 3. There are also floor spikes which are not active until Sonic steps onto them. If he steps on them, he has to jump quickly before they spike up. There are also spikes along certain walls, a machine that sends out spiked missiles every so often, and in Act 2, tall spikes that pop out from holes in the ground when Sonic approaches them.
