In gameplay, the Fireball can only be obtained at random from Item Boxes by Knuckles, Sonic, Vector, and Zavok. As with most other Items, Metal Sonic can also use the Fireball if he uses the Steal Item to steal it from the aforementioned users.
When used, it will fly down the lane it was deployed on at high speed. However, it will dissipate when it hits a player, collides with an obstacle, or travels off course. Opponents hit by the Fireball will be slowed down heavily and lose Rings. Players also have a chance to find two Fireballs in an Item Box instead of one if their level is at least 6, and three Fireballs at level 12.
Zavok starts out with a level 2 Fireball immediately when unlocked, and can level it up to level 4, which gives him a guaranteed chance to find two Fireballs in an Item Box if he is in second place or lower. He also still retains the chance of getting three Fireballs.
In order to avoid the Fireball, the player must either jump over it or step out of its lane.
