Sonic the Hedgehog Pocket Adventure
This zone is an 8-bit conversion of Casino Night Zone from Sonic the Hedgehog 2, with very similar level design. In this stage, the player must navigate through a casino-themed area filled with bumpers and various other obstacles as Sonic the Hedgehog. In the end, Dr. Robotnik will face Sonic in a vehicle which haphazardly bounces around the arena with the bottom electrified. This unique boss has only appeared once in the series.
- The music of Act 1 is a remix of the gumball machine Bonus Stage from Sonic the Hedgehog 3.
- The music of Act 2 is a remix of the slot machine Bonus Stage from Sonic & Knuckles.
