Sonic 3 & Knuckles: The Challenges

In the main screen of the game, which resembles a Level Select, the player has a choice from twelve groups of challenges. In each challenge, they must accomplish a certain goal with a specific character and reach the end of the level, within the given time limit. On doing so, they receive a Rank based upon the amount of time left and their ”score”, a figure that depends on the content of the challenge itself.
