The game includes an extensive collectible card system that spans a total of 150 cards. Performing specific objectives throughout the game will give the player a collectible cards. Such tasks include finishing a level, getting a certain number of rings, hitting your rival a certain number of times and getting to the goal within a certain amount of time. The cards themselves feature pictures of characters and boxart from a variety of past games in the "Sonic" series. The cards themselves are used to unlock secret costumes and items that alter the appearance of the characters. While they add a customizable aspect to the game, they are merely aesthetic; they do not affect gameplay.
