Bowling Spin is encountered in a room with a floor made of yellow-and-green blocks that descends down a long vertical tunnel. Bowling Spin has a twirling spike-covered top that will bounce around the room and destroy the yellow-and-green blocks on the floor. The rest of the boss will hover from side to side all the time and will only stop when hit by Sonic. The spinning top also acts as a platform.
This boss must be completed quickly as eventually the whole floor gets destroyed leaving Sonic to fall to his death. To compensate for this lack of time, this boss is weaker than the other mini-bosses and must only be struck four times rather than six. However, Sonic cannot damage the Bowling Spin directly. When Sonic hits it, the tube on the bottom extends (as in the picture) and surrounds itself with an electric field that will hurt Sonic if he touches it. The spinning top has to then hit this part of the mini-boss to score a hit.
After the Bowling Spin has been destroyed, the falling floor will reach the bottom and the goal sign will drop from the top of the screen. Sonic can safely fall down through any gaps that may have opened up in the floor at this point, but runs the risk of being crushed as the rest of the blocks come down.
- The Bowling Spin's ability to destroy the floor of the battle arena is reminiscent of the boss of the Spring Yard Zone in Sonic 1.
- Strangely, a Lightning Shield does not protect the character from hitting the electric field that forms around the tube on the bottom of the boss (the shield is lost as soon as such a hit is sustained).
- Jumping up into the Spinning Top from below forces it upwards.
