Medal Corner is a place where all the bonus games in the Rhythm Heaven series are unlocked. They all work very differently than the main rhythm games unlocked through "Just OK" and "Superb" ranks although their controls are similar. These bonus games are unlocked through collecting a number of medals on the other rhythm games.
There are two areas in the Medal Corner that are available in each installment. These are Endless Games and Rhythm Toys. Other sections in the Medal Corner are also available exclusively to each title.
