As the name suggests, Speed Slider has a high emphasis on speed and is built for characters such as Mighty and Espio, as they are among the fastest characters in the game. This stage includes balloons (which can be used as springs in the air), big bells (which can send the player to a lower section of Speed Slider), and a spring that sends the player upwards if stood on for a while. The stage's music is high-speed and upbeat, fitting the stage and its name.
The boss sees the player and their partner trapped near a carousel from which Dr. Robotnik will launch a rocket, while Robotnik himself hides in the center of the machine. Although this ride resembles a carousel, the "horses" on poles are replaced by spiked platforms. The player is unable to move around normally because the floor is rotating. If the player attempts to move around by jumping, he/she is exposed to the spiked platforms. In order to defeat the boss, the player must successfully hit the blue Dark Ring rotating around its middle eight times, while avoiding the platforms.
