Endless Games

Endless Games is a menu in the Bonus section which consists of games that are played for an infinite amount of time, until the player makes a certain amount of mistakes. Unlike Rhythm Games, these are played with the objective of earning a high score, which increases to show how far the player has gotten. These games are unlocked by earning Medals.

Trivia
In Rhythm Heaven Megamix, there is no actual endless game menu. Instead, the endless games are played in the middle of the story mode, presented as a gate with three challenges of varying difficulty. Clearing all three challenges will then unlock the game as an endless game in the Museum.
