- For Special Stages in general, see here.
Special Stages in Sonic Blast are a series of ten special levels that come in sets of five. Here, the playable character is running forward on a huge checkerboard arena with mountains in the background. To enter a Special Stage, the player must find the Giant Ring hidden in one of the two Acts of each Zone. It should be noted that Act 2 Special Stages grant Chaos Emeralds as a reward for completing them, while Act 1 Special Stages grant 1ups.
When entering a Special Stage, the player's goal is to collect 50 Rings in order to receive a Chaos Emerald/1up as a reward. The player controls Sonic the Hedgehog/Knuckles the Echidna, who are constantly moving forward. The player can move sideways by pressing left or right on and use the Spin Jump. As the player moves forward, lines of Ring will appear, some of which can only be reached by jumping. In terms of gimmicks, the Special Stages contain Dash Panels for Ring collecting, Bumpers for misdirecting the player, and red Spring for reaching mid-air Rings.
Special Stages found in Act 1 feature green checkerboard terrain and reward a 1up, while Special Stages found in Act 2 have red checkerboard terrain and reward Chaos Emeralds. Both types of Special Stages have five different layouts. If the player fails to collect 50 Rings, Dr. Robotnik will fly past the screen and steal the 1up/Chaos Emerald in front of the player. The player will be then sent back to the latest Marker in the Act. Collecting all five Chaos Emeralds will give the access to hidden final boss in Silver Castle Zone Act 3.
